01 — About

The Engineer Behind the Code

I'm a results-driven Software Engineer with 3+ years of hands-on experience building production-grade web applications on the MERN stack. My work spans the full engineering lifecycle — from designing resilient backend architectures to crafting performant, accessible frontend experiences.

At Ilmversity, I've scaled a cloud-based Learning Management System to serve 50,000+ daily active users, modernized a legacy PHP codebase into the MERN ecosystem, and achieved a 60% boost in backend performance through Redis caching and advanced MongoDB optimization.

I specialize in cloud-native integrations (AWS S3, EC2), real-time systems with Socket.io, automated CI/CD pipelines via GitHub Actions, and third-party API ecosystems including Zoom, Google Calendar, and Stripe. I bring both technical depth and a product mindset to every project I touch.

Where I've Built

Full-time engineering experience delivering production systems at scale.

Software Engineer

Ilmversity

Mar 2023 – PresentLahore, Pakistan
  • Actively architected and scaled a cloud-based LAAMS (Learning Academic Administrative Management System), using the MERN stack (MySQL, Express.js, React.js, Node.js) for full-stack development.
  • Optimized backend performance using Redis caching, efficient MySQL query design (JOINs, subqueries, GROUP BY), and indexing strategies, improving response times and system throughput.
  • Built and maintained RESTful APIs with dynamic query generation, delivering context-aware responses tailored to user roles, application configurations, and client platforms (web and mobile), ensuring secure and efficient backend communication.
  • Built responsive and dynamic frontend interfaces using React.js, Redux, and modern JavaScript (ES6+), ensuring efficient state management and improved user experience.
  • Implemented secure authentication and authorization mechanisms using JWT, role-based access control, and multi-factor authentication, along with Socket.io for real-time, secure communication.
  • Established CI/CD pipelines using GitHub Actions and deployed scalable services on AWS (EC2, S3), ensuring reliable and automated delivery workflows.
  • Monitored production systems, debugged live issues, and resolved server-side exceptions to maintain system stability for active users.
  • Collaborated within an Agile development environment to design, develop, and deliver high-impact features.

CodeLens — AI Code Review Assistant

A full-stack MERN code review platform where developers paste source code and receive a structured quality report instantly. The backend automatically runs ESLint for JavaScript/TypeScript or Flake8 for Python — no manual linting required. AI mode sends code to Claude for deeper semantic analysis. Reviews are persisted in MySQL and browsable via a history dashboard.

  • Auto-runs ESLint or Flake8 on the backend — no client-side tooling needed
  • Dual review modes: rule-based Linter and semantic Claude AI analysis
  • Structured JSON report with severity levels, score, and actionable suggestions
  • Paginated review history dashboard with per-language stats

March Shortify — URL Shortener

A production-ready URL shortener where developers paste a long URL and instantly get a shareable short link. Supports custom slugs, tracks click counts per link, and persists all data in a serverless PostgreSQL database via Neon. The backend runs Prisma migrations automatically on startup. The entire app is containerized with a multi-stage Docker build for a minimal, deploy-anywhere image.

  • Custom slug support with conflict detection and a 409 error response
  • Click tracking per short link with a paginated history dashboard
  • Multi-stage Docker build with alpine base and Next.js standalone output for minimal image size
  • Auto-runs Prisma migrations on container startup — zero manual DB setup

Canyon

A full-stack, ChatGPT-style AI chat platform with a React 19 client and an async FastAPI backend. Conversations blend streaming text, generated images, and voice — backed by an LLM-driven intent router, a pgvector-powered Policy RAG engine, and a credits-based usage system, all behind cookie-based session authentication.

  • Async FastAPI backend with an LLM-driven intent router directing requests across chat, image, audio, and RAG modules
  • pgvector-powered Policy RAG engine for grounded, context-aware responses
  • Full voice pipeline — live waveform recording, transcription, and edge-tts speech synthesis with auto-playback
  • JWT/cookie session authentication paired with a credits-metered usage system
