CI/CD pipelines — automated deployments

Code reviews — every PR reviewed by a senior

-
Global CDN — fast for users anywhere

Image optimisation — auto WebP & lazy load
-
SEO-ready — schema, sitemaps, meta built in

What clients say.
TekGenie built our entire booking platform from scratch. It's fast, reliable, and their handover documentation was outstanding. Two years on, we still work with them.
Our new website loads in under 2 seconds and our Core Web Vitals score is 98/100. Organic traffic is up 40% in 3 months. Best investment we've made this year.
Common questions.
Custom web applications typically start from £15,000 for a focused MVP and range up to £100,000+ for complex platforms. Marketing websites start from £4,000. We provide a fixed-price proposal after the discovery call — no hourly billing, no surprises.
Marketing websites: 4–6 weeks. Custom MVPs: 8–12 weeks. Enterprise platforms: 4–6 months. We work in weekly sprints with Friday demos, so you always see real progress.
We're technology-agnostic but typically build with React, Next.js, Node.js, Python, PostgreSQL, and deploy on AWS or Vercel. For marketing sites we use WordPress, Webflow, or headless CMS platforms. We always choose the best tool for the specific project.
Yes. Every project includes 30 days of post-launch support. Beyond that, we offer monthly retainers that cover monitoring, security patching, and feature iterations — starting from £500/month for smaller sites.
Absolutely. We regularly take over projects from other agencies or in-house teams. We start with a technical audit, then agree on a handover plan — typically taking 1–2 weeks before we start building.
