I’m a Full-Stack Developer Intern in London who ships end-to-end products and enjoys turning fast prototypes into production-ready systems. I recently architected and independently shipped Hoomanpets.com—from system design to Cloudflare deployment—serving a live, growing user base.

I lead full-stack development using React.js, Node.js, Express.js, and Neon, delivering 10+ production features with a 2–5 day turnaround per feature. I also integrated LLMs via the OpenAI API to automate recommendations and content generation, reducing manual content effort by 70%, and I strengthened security with JWT authentication and RESTful APIs while maintaining zero downtime in production.

Beyond my internship, I build practical AI tooling through projects like an AI Job Automation Agent that submits 60+ job applications/day with zero manual input, using Playwright for browser automation and a Telegram notification pipeline with deduplication and application tracking for 100% submission accuracy. I also created ENSO, a dual-AI learning intelligence system combining Gemini and OpenAI APIs to summarize sessions and smart-autotag content, boosting engagement by 15%, while improving performance and data throughput through redesigned architecture.
