What I'm looking for

I’m looking for a role where I can build secure, scalable full-stack web applications—owning API design, responsive UIs, deployments, and AI/LLM features—while collaborating with teams to deliver real business impact.

I’m a results-driven Full Stack Web Developer with a Bachelor’s degree in Computer Applications and 2.5 years of total experience, including 2 years of industry and 6 months of freelance delivery. I focus on building scalable, high-performance web applications that translate real business goals into reliable software.

In my recent industry work, I designed and maintained secure enterprise-grade systems, Web APIs, and responsive web portals. I implemented robust OAuth 2.0, JWT authentication, and cryptography to establish secure communication pipelines between government systems and financial organizations.

I’ve owned end-to-end deployments and performance optimization across IIS and Contabo VPS, handling server hosting, database configurations, and maintenance workflows. I also collaborate cross-functionally to integrate modern AI workflows while keeping application reliability high.

My projects blend full-stack development with AI/LLM capabilities—like an AI personal finance tool using OpenAI API and a context-restricted RAG chatbot that prevents hallucinations via targeted local data. I’ve also led a Laravel to Next.js frontend migration, improving load times and resolving UI issues while preserving the existing backend via REST APIs.
