About Me

Full-stack developer and technical project manager with 5+ years of hands-on experience building and delivering production-ready web systems across hundreds of client projects. I own the full lifecycle — from technical planning and architecture through to development, delivery, and measurable outcomes. I don’t just manage teams; I build alongside them, which means the quality, performance, and scalability standards I set are ones I can enforce from first-hand experience.

My work spans full-stack web development, technical project management, and product strategy — with a sharp focus on making technology directly serve business goals. I regularly integrate performance engineering, technical SEO, automation, and data-driven decision-making into every project I take on.

I’ve also delivered work through international client platforms, which has given me a clear understanding of global expectations, tight deadlines, and cross-cultural delivery standards.

Academically, I hold a Bachelor’s in Computer Science & Engineering (CGPA 3.93/4.00) and have deep grounding in AI, Machine Learning, Deep Learning, and Data Science — including a peer-reviewed publication, SMILES2DTA, in Neural Computing and Applications (Springer, Q1 — Impact Factor 4.5, 2023). This research background directly shapes how I think about complex technical problems and scalable product decisions.

Recognized with Dean’s Awards, Programming Contest Championships, and Problem-Solving Awards — and hold multiple industry certifications across the stack.

If you’re looking for a developer who can think strategically, execute technically, and take ownership end-to-end — let’s talk.
