I build fast web apps and serverless AWS backends that scale for less.

Full-stack developer & architect with 5+ years and 50+ projects: React, Next.js and TypeScript on the front, Node.js, Python and AWS behind it. I help startups and businesses ship SaaS products, marketplaces and high-converting websites.

04 — How I can help

Ways to work together.

MVP to production: Next.js front end, Node.js or Python APIs, auth and payments.

Fast, animated marketing sites in Next.js or Webflow + GSAP, built for leads and SEO.

Lambda, API Gateway, AppSync, Cognito and DynamoDB, with tenant isolation from day one.

AI-assisted workflows like LedgerIQ’s mapping engine, plus LangChain, Bedrock and n8n automations.

Docker, ECS, blue-green releases, CodePipeline and GitHub Actions. Zero-downtime shipping.

I review your setup and show where money and latency leak.

05 — Process

What working with me looks like.

01

Discovery call

30 minutes on goals, users, constraints and budget.

02

Architecture & estimate

A written plan, cost forecast and fixed scope.

03

Build in weekly sprints

A demo every week, code in your repo from day one.

04

Launch & support

Monitoring, handover docs and optional retainer.

06 — About & experience

I handle everything from the interface to the infrastructure, so products ship faster and scale cleanly.

I help startups and small businesses build full-stack web applications that scale efficiently: frontends, backend APIs, databases and AWS infrastructure. I care about clean architecture (DDD, SOLID), observability, and systems that are as simple as possible but no simpler.

07 — FAQ

Before you ask.

Yes. I’m in Karachi (UTC+5) and keep a daily overlap window with US and EU working hours for calls, reviews and quick decisions. Everything else moves async with written updates.

All three. I take on freelance projects and longer contracts, and I’m open to the right full-time role.

Either. Well-scoped projects get a fixed price after the architecture & estimate step. Ongoing or open-ended work is billed hourly or as a monthly retainer.

Yes. I regularly work inside existing teams, repos and pipelines, follow your conventions, and leave the codebase better documented than I found it.

A 30-minute review of your AWS setup. I show where money and latency leak and hand you a short list of fixes ranked by impact.
