Full stack development, end to end

From responsive frontends to scalable APIs and database architecture — complete web applications built with Next.js, TypeScript, FastAPI, and PostgreSQL, shipped fast without cutting corners.

Five-plus years across the whole stack: Next.js App Router frontends with server components where they belong, REST and GraphQL APIs in FastAPI or Next.js route handlers, PostgreSQL schemas with reviewed migrations, and Docker-based deployment with CI/CD. Typed end to end — the bugs a compiler can catch should never reach a user.

The shipped record covers the shapes most businesses need: GymHub, a SaaS dashboard with role-based access, real-time scheduling, and payments; Modern Atelier, a multi-vendor marketplace with separate customer, vendor, and admin portals over one source of truth; and Klyent, an agency platform whose bi-directional Wix–HubSpot sync cut manual data entry by 80% across 50+ client accounts.

Increasingly, full stack includes an AI layer — semantic search, agents, automation — and that's native territory for me rather than a bolt-on: the same build can include the RAG pipeline and the dashboard that monitors it.

What you get

  • Product builds from MVP to production — frontend, backend, database, deployment
  • SaaS dashboards with role-based access control and real-time data
  • E-commerce and marketplace builds, including multi-vendor architectures
  • API design and integrations — REST, GraphQL, third-party platforms
  • PostgreSQL schema design with versioned, reversible migrations
  • CI/CD pipelines, Docker packaging, and deployment (Vercel, Render, or your cloud)
  • Performance and accessibility passes — Core Web Vitals treated as a feature

How an engagement runs

  1. Scope and architecture

    What the product must do, what it must never do, and the data model — written down before code, so the build doesn't discover requirements mid-sprint.

  2. Weekly shippable increments

    Working software every week on a preview URL, not a big reveal at the end. Course corrections are cheap when the feedback loop is short.

  3. Production hardening

    Error states, loading states, empty states, auth edges, slow-network behavior — the difference between a demo and a product.

  4. Launch and handover

    Deployment, docs, and a recorded walkthrough. Your team can operate it without me — and a retainer exists if you'd rather not.

Proof, not promises

Common questions

How long does an MVP take?
A focused MVP — one core workflow done properly — typically lands in 3 to 6 weeks depending on integrations and auth complexity. The honest variable is scope discipline: weekly increments make progress visible, so there are no surprises in week five.
Can you work inside an existing codebase?
Yes — much of my agency work at Lusion Tech and Avialdo Solutions has been extending production systems serving real users across e-commerce, SaaS, and education. First step is always a read-through and a map of what's load-bearing before anything is touched.
Why Next.js?
Server rendering and static generation give you the SEO and performance a marketing site needs, while the App Router, server components, and TypeScript give application code real structure. One framework covers the landing page and the product behind the login — fewer moving parts to operate.
Who maintains it after launch?
You own everything — code, infrastructure, docs. Handover includes a walkthrough recording and runbooks. If you want ongoing support, I offer a maintenance retainer; if not, the project is structured so any competent team can pick it up.
