PTAS AI · Web Development Services

Websites that do the job. Not just take up the homepage.

We build custom websites, web applications, e-commerce platforms, and API-first back-ends for teams that need the site to run onboarding, move money, or close a sale — not just look clean in a pitch deck. Written in the stacks your team already supports. Tuned for Core Web Vitals. Handed over with documentation that matches the code.

What we build

Nine ways we ship a website

Pick the engagement that matches where you actually are — a fresh build, a rescue job on something slow, a portal behind a login, or an API layer for the next app your team is planning.

Custom Website Development

Built from the blank canvas up. No recycled themes, no plugin towers waiting to break on the next update. The markup is semantic, the CSS is readable, and your in-house team can pick up the repo without calling us.

  • Clean, maintainable codebase
  • Component-driven architecture
  • Accessibility checked to WCAG 2.2 AA
  • CMS wiring when you need one

Progressive Web Apps

PWAs that keep working when the network doesn't. Installable on the home screen, quick to boot, and honest about what they can do offline. Useful when a native app is overkill but mobile-first is non-negotiable.

  • Service workers with sensible caching
  • Offline-capable UI and data sync
  • Push notifications where they earn their keep
  • One codebase across iOS, Android, and desktop

E–commerce Development

Storefronts built to convert. Catalog, cart, checkout, inventory, tax, and the 40 edge cases nobody writes into the RFP. Headless on Shopify, Medusa, or WooCommerce, or a custom platform when the catalog size justifies it.

  • Custom product catalogs and variants
  • Payment gateway and 3DS integration
  • Inventory and order workflows
  • Checkout tuned to your actual funnel

Performance Optimization

The site you already have, made fast enough to keep. We profile what's actually slow, cut the JavaScript nobody needed, compress the hero image someone forgot to optimise, and put the rest behind a CDN.

  • Bundle analysis and code splitting
  • Image, font, and asset optimisation
  • Database query tuning and indexing
  • CDN, cache, and load-balancing review

API Development

REST and GraphQL APIs your other systems can actually integrate with. Versioned, rate-limited, documented, and secured with OAuth 2.0 or signed JWTs. We ship the OpenAPI spec alongside the endpoints, not six months later.

  • REST, GraphQL, and webhook endpoints
  • OAuth 2.0, JWT, and API key auth
  • Rate limits, quotas, and audit logs
  • OpenAPI and Postman collections out of the box

Enterprise Web Solutions

Business applications for the parts of your company still running on spreadsheets. SSO, role-based access, audit logs, and integrations with your ERP, CRM, or whatever else finance refuses to let go of. Built to pass an internal audit.

  • ERP and CRM connectors
  • SSO with Okta, Azure AD, Google Workspace
  • Workflow automation and approvals
  • Reporting and BI dashboards

SEO-Friendly Web Design

Technical SEO baked into the markup, not bolted on by a plugin after launch. Semantic HTML, clean URLs, JSON-LD schema, fast Core Web Vitals, and a sitemap that actually reflects what's on the site.

  • Semantic HTML and JSON-LD schema
  • Clean, canonicalised URL architecture
  • Optimised Core Web Vitals (LCP, CLS, INP)
  • Mobile-first rendering and image handling

Web Application Development

Customer portals, internal tools, document platforms, analytics dashboards. The web apps your team opens every morning and closes at 6pm. Built around real workflows, not a wireframe someone sent over in a PowerPoint.

  • Customer and partner portals
  • Internal CRMs and ops tools
  • Document management platforms
  • Analytics and reporting dashboards

Cloud-Ready & DevOps-Enabled

Containerised from commit one, deployed on AWS, Azure, or GCP, and wired to a CI/CD pipeline that runs the tests before it ships. Rollback is a button, not a war room.

  • Docker and Kubernetes-ready builds
  • CI/CD with GitHub Actions, GitLab, or Azure DevOps
  • Auto-scaling and load balancing
  • Monitoring, logging, and alerting
Industries we build for

Nine sectors. Same delivery team.

We've shipped against the regulatory mess of healthcare, the uptime demands of fintech, and the catalog sizes of retail. The stack changes. The rigour doesn't.

Finance & FinTech

Payments, lending platforms, risk dashboards, and customer onboarding flows. KYC, audit trails, and the paper trail your compliance team asks for on day one.

Education

Learning platforms, LMS builds, student portals, and the analytics that tell educators which students actually need attention this week.

Real Estate & Hospitality

Booking engines, channel managers, property portals, and the guest-experience layer that turns a one-night stay into a five-star review.

E-commerce & Retail

Storefronts that load on 3G, inventory systems that reflect the warehouse in real time, and checkout flows we've A/B tested against actual traffic.

Healthcare

HIPAA-ready patient portals, electronic records, telemedicine front-ends, and the interoperability work that makes two EHRs talk to each other.

Manufacturing

Shop-floor dashboards, supply-chain visibility, quality-control workflows, and integrations with the MES your plant engineer already trusts.

Logistics

Fleet tracking, warehouse management, route optimisation, and the live shipment views your customer service team refreshes every two minutes.

Technology & SaaS

Subscription platforms, admin consoles, billing portals, and the usage-based pricing pages product marketing keeps rewriting.

Professional Services

Client portals, document collaboration, engagement trackers, and the CRM-plus-billing combination consulting firms keep asking for.

Technology stack

Boring technology, deliberately chosen

We pick the stack your team can maintain after we leave. Mostly that means the tools below. We can defend each choice in a room full of engineers — and we have.

Frontend

React Next.js Vue.js Angular TypeScript Tailwind CSS Astro

Backend

Node.js Python .NET Core Java Go PHP Ruby on Rails

Database

PostgreSQL MySQL MongoDB Redis Oracle SQL Server Elasticsearch

Cloud & DevOps

AWS Azure Google Cloud Docker Kubernetes Terraform GitHub Actions
How we deliver

Five stages, no surprises

The same delivery shape across every engagement — scaled up for a multi-team enterprise rollout, scaled down for a four-week marketing site. Fewer late-night heroics, more boring predictability.

Discovery & Strategy

Audit what you have, map the journeys that matter, and write the plan the team will actually follow.

Design & Architecture

Wireframes, a component library, and the system diagrams. Stack, hosting, and data-model choices decided — and documented.

Development & Testing

Two-week sprints, pull-request reviews on every merge, automated tests, and a staging environment your stakeholders can click through.

Deployment & Launch

Blue-green or canary rollout, monitoring wired up before go-live, and a rollback plan in writing. On-call starts the moment traffic hits.

Maintenance & Support

SLA-backed support, scheduled dependency patching, and a named engineer who answers when something breaks at 2am.

Security & data protection

Security is part of the build. Not a ticket for later.

Most breaches are dull: an unvalidated input, a dependency nobody patched, a secret checked into a public repo. We design the build so the dull stuff can't happen.

TLS everywhere

HTTPS on every route, HSTS preloaded, modern cipher suites, and certificates auto-renewed. Logins, payments, and session tokens don't travel in the clear — ever. HTTP redirects are permanent, not optional.

SQL injection, shut down at the source

Parameterised queries and ORM-level safeguards across the whole stack. Input is validated server-side, never trusted from the browser. Database accounts run with the least privilege that keeps the app working, nothing more.

XSS protection that doesn't need a disclaimer

Output encoding on every rendered value, CSRF tokens on state-changing routes, and framework-level defences kept on, not switched off for convenience. Rich-text inputs go through a sanitiser with an explicit allowlist.

Content Security Policy, tuned to the app

A CSP scoped to the domains the app actually needs, reported-on in CI, and tightened as the build matures. No "unsafe-inline" free passes. Mixed content gets caught before it reaches production, not after.

Why teams pick us

What you get that you probably didn't have before

We're not the cheapest web shop. We're also not a consultancy that subcontracts the actual coding. Four reasons teams stick with us past the first release.

SEO-first development

Technical SEO is in the markup from day one, not retrofitted after launch. Your site ranks because the code deserves to, not because someone bought backlinks.

Full-stack engineers, not juniors

Everyone on the delivery team has shipped production code for someone who depended on it. The frontend person understands the database. The backend person can debug CSS when they need to.

Scale headroom built in

We don't over-engineer for ten users. But the bones are there for a hundred thousand — stateless services, managed databases, a CDN, and caching layers where the profile says they earn their keep.

Transparent communication

A shared Slack channel, weekly demos, and a status board anyone on your side can read. If something slips, you hear about it on Tuesday — not in the Friday status email.

FAQ

Questions we hear on the first call

If yours isn't here, a 30-minute discovery call is usually faster than email.

How long does a typical web development project take?

Marketing sites and landing pages ship in four to six weeks. A custom web application with authentication, integrations, and a real database usually takes ten to sixteen weeks. E-commerce builds with payments, inventory, and tax logic sit in the twelve to twenty-week range. Anything shorter than that is usually a template rollout, not custom development — which is fine, just a different conversation.

Is SEO included in the development work?

Technical SEO is part of the base price. Semantic HTML, clean URL structure, meta tags, Open Graph, JSON-LD schema, a proper sitemap, robots.txt, and Core Web Vitals tuning all ship with the site. Content strategy, keyword research, and link building are separate engagements we hand to partners who live and breathe that work.

Can you scale the site as traffic and features grow?

Yes. Every build targets horizontal scaling from day one. Stateless services behind a load balancer, managed databases with read replicas when the profile calls for it, asset delivery through a CDN, and cache layers where they measurably help. We don't over-engineer for ten users. But when the first marketing push hits and traffic goes 20x overnight, the site doesn't fall over.

Do you offer post-launch support?

Three tiers. Bronze covers business-hours email support and monthly dependency updates. Silver adds on-call response within four hours and quarterly security reviews. Gold is a named engineer, 24x7 paging for critical issues, and a rolling pool of improvement hours every month. Contracts run 12 months and get reviewed annually — not locked in for five.

What stack do you typically recommend?

For content-heavy sites, Next.js or Astro on Vercel or CloudFront. For web applications, React or Vue on the front, Node.js, Python (FastAPI or Django), or .NET Core on the back, Postgres as the default database. For heavy internal tools, Django or Rails still earns its place when the team behind it is more comfortable in those frameworks. The right answer is the one your team can maintain after we leave — that's the filter we run every recommendation through.

Can you work with our existing in-house development team?

Most of our web engagements are hybrid. We lead architecture and the first release, your engineers pair with ours, and ownership transfers over the course of the project. The code and documentation we produce is built to survive that handoff, because we want the phone to stop ringing eventually. If you'd rather we stay fully in charge, that's also fine — but it's not the default.

How do you handle security and compliance?

ISO 27001-aligned practices on our side. On your build: TLS everywhere, parameterised queries, server-side input validation, output encoding, a CSP tuned to the app, dependency scanning in CI, and secrets in a vault — not in the repo. HIPAA, PCI-DSS, SOC 2, and GDPR-specific requirements get scoped at the start and baked into the architecture, not retrofitted two weeks before launch.

What happens if the original developer leaves the project?

Nothing visible from your side. Every project has at least two engineers familiar with the code, a written architecture document, an up-to-date README, and a runbook for the incidents we expect to see. We run bus-factor reviews every quarter on long engagements. The goal is that any engineer on our team can pick up your project inside a day — not that you're hostage to whoever wrote the first commit.

Can you work with our existing design system or Figma files?

Yes. We've built from detailed Figma handoffs, rough Whimsical sketches, and "here's a competitor we like" starting points. If you have a design system already, we implement against it and flag the places where the design doesn't quite work in code. If you don't, we can build one alongside the project — it's usually cheaper than you'd expect.

How is a web development project priced?

Fixed-price for well-scoped work with a clear set of deliverables, typically for marketing sites and feature-scoped web apps. Time-and-materials on engagements where the requirements will evolve week to week — which is honest on both sides, because the alternative is padding the fixed price to cover unknowns. Either way, you see the rate card, the team, and the timeline before anything is signed.

Send us a link to what you have now.

A URL, a Figma file, or a sentence about what the site needs to do next. We'll come back with an audit, a realistic timeline, and the names of the engineers who'd work on it. No slide deck. No 40-page proposal.
