Haroon W.

Full-Stack Engineer | Web Apps, APIs & AI Automation

I help businesses build, improve, and modernize web applications from frontend to backend, including APIs, dashboards, integrations, database logic, automation workflows, and production bug fixes. I have 5+ years of experience working on real production systems, including ecommerce platforms, educational products, backend services, admin panels, payment integrations, SMS and notification flows, and database-heavy applications. I have worked with platforms like Inspire Uplift, 1Cademy, and Blomal, where reliability, clean code, and maintainable architecture are very important. My main strength is understanding existing products quickly and improving them carefully. I can work across the full stack, from UI issues and frontend features to backend APIs, database problems, third-party integrations, performance improvements, and production debugging. I work with Laravel, Node.js, TypeScript, Python, React, Next.js, Vue, Nuxt, Django, Flask, FastAPI, and Rust. I can also help with AI-related features such as RAG implementation, vector search, embeddings, LangGraph workflows, automation pipelines, and AI-assisted internal tools. Over the last year, I have been using AI seriously in my development workflow. I use tools like Claude, Codex CLI, Antigravity, and custom local workflows for agentic coding, code review, debugging, automation planning, technical analysis, and faster delivery. I still review and validate the final code carefully, so the work stays reliable and production-ready. What I can help you with: * Full-stack web application development * Backend APIs, admin panels, dashboards, and integrations * Laravel, Node.js, TypeScript, Python, Django, Flask, FastAPI, React, Next.js, Vue, Nuxt, and Rust work * Database design, SQL optimization, MySQL, PostgreSQL, MongoDB, Redis, and vector database implementation * RAG systems, embeddings, vector search, LangGraph workflows, and AI automation pipelines * Payment, SMS, email, OAuth, Google API, Stripe, Twilio, SendGrid, and third-party integrations * Code review, refactoring, debugging, and performance improvements * Production issue fixing, race conditions, failed jobs, notification flows, and API errors My approach is simple. I first understand the business logic, review the existing code carefully, identify the real issue, and then make changes in a safe and maintainable way. I do not just try to make something work. I focus on clean code, edge cases, testing, and avoiding regressions. If you need someone who can understand your product, improve it carefully, and use modern AI-assisted workflows to move faster without sacrificing quality, feel free to send me a message.
