Project details

A bad API quietly taxes everything built on top of it. I build back ends that don't clean architecture, typed code, real validation, and the auth and error handling that production actually needs.

I work in NestJS and Node/Express with PostgreSQL (TypeORM/Prisma) and MongoDB, plus Redis/BullMQ for queues and jobs, and Socket.io for real-time. I've shipped back ends for e-commerce (products, cart, orders, Stripe & PayPal checkout), multi-tenant SaaS, ticketing, and fintech including JWT/OAuth auth, role-based access, transactional email, file uploads (AWS S3 / Azure Blob), and third-party integrations (Stripe, Finix, Twilio, Sendbird, OpenAI).

You get documented REST endpoints, a sensible data model with migrations, auth, and a back end deployed to staging or production. I keep PRs small, write tests where they matter, and document the non-obvious decisions.

Karachi, Pakistan - 7:52 am local time
I help founders, startups, and businesses turn ideas into working products.

I am a Full Stack Developer who can work across web, mobile, backend, SaaS, dashboards, and AI-powered features. I have experience building products using React, Next.js, React Native, Node.js, NestJS, Express.js, MongoDB, MySQL, Firebase, AWS, payment APIs, authentication systems, and third-party integrations.

I can help you build an MVP, improve an existing product, add new modules, fix broken flows, create admin dashboards, connect backend APIs, integrate payments, build mobile app features, or add AI automation into your platform.

I do not only focus on writing code. I try to understand what the feature is supposed to do, how users will interact with it, and what the simplest reliable solution should be. This helps avoid unnecessary complexity and saves time during development.

I can also work with AI APIs and automation tools, including OpenAI, Claude, Gemini, ElevenLabs, Google Cloud APIs, and other third-party services. Whether you need an AI assistant, content generation feature, voice feature, workflow automation, or AI-powered product module, I can help with the integration.

You can expect clear updates, honest timelines, proper testing, and a developer who takes ownership of the work.
