01.About Me
I'm a Senior Software Engineer with over a decade of experience building high-performance web and mobile applications across Ad-Tech, E-Commerce, SaaS, and EdTech industries. Currently at Shopsense AI, where I architect serverless systems on AWS handling 50K+ daily ad impressions.
My expertise spans the full stack — from crafting pixel-perfect React interfaces to designing cloud infrastructure with AWS CDK, Lambda, and DynamoDB. I've led teams, built design systems used by 40+ engineers, and consistently delivered measurable performance improvements (60% CWV boost, 20%+ engagement increase).
I use AI as a force multiplier — not a crutch. It helps me ship 3x faster while maintaining code quality I can defend in any review. This portfolio was built with AI assistance, and every line is production-grade.

How This Portfolio Was Built
This portfolio is itself a technical showcase — a Turborepo monorepo with two Next.js apps, server-side AI chat, and edge-cached performance.
Built with AI Assistance
I used AI tools (Cursor + Claude) to accelerate development of this portfolio — architecture design, code generation, and content optimization. Every decision was validated, every line was reviewed. AI is my co-pilot, not my autopilot.
