Production web apps, end to end
From the database schema to the deployed Next.js frontend, I ship modern web apps designed to rank, convert, and scale. One engineer, full ownership.
Most agencies hand off between 3-5 vendors. I cover the full stack - database, API, frontend, SEO, and deploy - so nothing falls between the cracks. 4+ years shipping production traffic for FinTech, SaaS, and enterprise teams.

Everything included in every engagement
No upsells. No surprise change orders. One scope, one price.
Modern Next.js or React frontend
Server Components, App Router, TypeScript strict, Tailwind, Framer Motion. Pixel-perfect, accessible, and fast - 95+ Lighthouse on real production data, not synthetic demos.
Node.js APIs that scale
Express or NestJS with typed routes, JWT auth, validation, rate limiting, OpenAPI docs, and structured logs. Built to take 10K+ requests a day at 99.9% uptime.
PostgreSQL or MongoDB
Schema-first design with proper indexing, migrations, and Row-Level Security in Supabase or Prisma. Queries that stay sub-100ms as the table grows.
AWS, Vercel, or Supabase deploy
CI/CD on GitHub Actions, zero-downtime deploys, preview environments per PR, automated rollback, and edge caching. The boring stuff that matters.
SEO baked in from day one
Server-rendered metadata, JSON-LD structured data, automatic sitemap, OG images, and Core Web Vitals tuned to pass on real-world devices.
Tested and documented
Integration tests for every critical path, OWASP-aware security review, and a written handover doc. You don't get locked into me - you can hand the codebase to anyone.
Results that build trust
The numbers behind the work - measured on real production data, not demos.

AWS Certified
Solutions Architect
I'm Smit Parekh - a full-stack developer who writes every single line of your code
With 4+ years of experience shipping production systems for FinTech, SaaS, and AI startups, I work as a senior individual contributor - no juniors on your project, no account managers between you and the work. Every commit, every architecture decision, every deployment lands on my machine first.
I specialise in the TypeScript ecosystem - React & Next.js on the frontend, Node.js / NestJS on the backend, PostgreSQL for data, and AWS for infrastructure. I've built headless e-commerce stores, multi-tenant SaaS platforms, real-time dashboards, AI-powered tools, and performance-first marketing sites. The common thread: clean code, zero tech-debt handover docs, and measurable business results.

Me vs. an agency vs. hiring in-house
Three ways to get this built. Here's the honest comparison.
Best value Solo Dev (me) $80-$120 /hr or fixed | Agency $150-$300 /hr blended | In-house hire $80-$120K /yr + benefits | |
|---|---|---|---|
| Start date | 1-2 weeks from quote | 4-8 weeks onboarding | 8-16 weeks to hire |
| Who writes the code | Senior dev - every single line | Junior assigned to your account | Whoever you manage to hire |
| Communication | Direct - you talk to who codes | Via account manager first | Direct, but management overhead |
| Flexibility | Scale up or down any time | Locked to contract length | Fixed headcount, hard to change |
| Code ownership | 100% yours, full handover docs | Depends on contract terms | Yours, but bus factor risk |
| Risk | Weekly demos, fixed scope | Scope creep & handoff gaps | Wrong hire = months lost |
Questions I get asked first
What's the typical timeline for a web app?+
An MVP with 3-5 flows usually lands in 2-4 weeks. A production app with auth, payments, and an admin dashboard takes 4-8 weeks. Larger or multi-tenant builds are scoped per milestone.
Do you work with existing codebases?+
Yes. I regularly take over legacy React or Next.js codebases, write a code-quality audit, and incrementally migrate to TypeScript strict, modern patterns, and a tested stack.
Who owns the code?+
You do, completely. Code is committed to your GitHub org, and there's no licensing or lock-in. Full handover documentation is part of every engagement.
Do you handle deployment and CI/CD?+
Yes - Vercel, AWS, Supabase, or your existing infra. Every project ships with GitHub Actions CI, preview environments per PR, and a documented production deploy.
Can you also handle SEO?+
Yes, technical SEO is baked into the build - server-rendered metadata, JSON-LD, sitemap, OG images, Core Web Vitals. For deeper content/keyword work, see /services/seo.
