I’m a Junior AI & Full-Stack Engineer focused on building practical automation and AI systems that create measurable business ROI. I enjoy working across the stack—Next.js/TypeScript on the front and Python/Node services on the back—so products ship end-to-end, not just as prototypes.

Recently, I shipped an internal admin CMS and landing page integration using TanStack (Router + Query) and TypeScript. I designed a typed REST contract, implemented JWT authentication with role-based access (admin/editor), and added basic audit logging so non-technical teams could manage content with near-real-time propagation.

I also built in-house marketing and lead generation automation with Playwright, replacing paid API providers (Apify, RapidAPI) and reducing data-acquisition costs by roughly 80%. To keep scraping stable at scale, I implemented cookie persistence and residential-proxy rotation, then developed semi-autonomous bots for posting, engagement, and DM outreach.

On the AI side, I co-developed an AI tutoring platform on Next.js 14 (App Router) and Supabase with real-time data sync for live sessions. I built a multi-agent system (Orchestrator, Validator, Socratic Tutor) that adapts question depth and implemented RSA-encrypted message passing between the Next.js client and Python/Node microservices for sensitive data.
