SoftwareEngineer—building things for the web

Who I Am

About Me

I'm Muhammad Haziq Nazeer — a full-stack software engineer who builds fast, beautiful, production-grade products end to end. On the backend I engineer secure, real-time, AI-powered systems with NestJS, FastAPI, PostgreSQL and AWS; on the frontend I love crafting polished, high-performance websites in Next.js and React, built to modern industry best practices. Promoted from intern to Associate Software Engineer in under a year, I've carried products from first commit to production at scale, serving hundreds of thousands of users. I don't just ship code that works — I build systems that stay fast and reliable, and interfaces people genuinely enjoy using.

I'm equally at home on both ends of the stack. On the backend I love real-time pipelines, AI integrations, secure authentication and clean data models; on the frontend I love turning ideas into smooth, pixel-perfect websites with thoughtful motion and detail. Whether it's a streaming inference pipeline or a landing page that has to feel alive, I follow modern industry best practices, sweat the details, and ship work I'm proud to put my name on.

How I Can Help

What I Build For You

Productised services backed by real, shipped systems. Hire me for a focused build, an ongoing contract, or to rescue something that's outgrowing its codebase.

Production REST & real-time APIs

Backend & API Engineering

Robust, well-structured backends in NestJS, FastAPI or Express — authentication, role-based access, background jobs and a PostgreSQL schema indexed to scale from day one.

REST / WebSocket APIsAuth & RBACPostgres + Prisma/TypeORMRedis & queues

Ship AI features that actually hold up

AI & LLM Integration

Streaming AI chat, voice agents and document/vision analysis with Anthropic Claude and OpenAI — provider fallbacks, rate-limit handling and output validation so a flaky model never breaks your product.

Streaming chatVoice (Realtime / WebRTC)RAG & taggingVision & PDF analysis

Idea → deployed product

Full-Stack Web Apps & MVPs

End-to-end builds on Next.js + a typed backend — dashboards, auth, billing and admin tooling. Ideal for founders who need a credible MVP shipped fast without cutting corners.
