About Me
Get to know me better
I'm a Full-Stack JavaScript Developer with 3+ years of professional experience, currently working at eSparkBiz, where I help build modern web applications used in real-world production environments.
Full-Stack Expertise: I specialize in building end-to-end web and SaaS products. On the frontend, I work extensively with React and Next.js, crafting clean, responsive, and user-friendly interfaces using Tailwind CSS and shadcn/ui. On the backend, I design and develop reliable, scalable systems using Node.js, along with PostgreSQL, MySQL, and Hasura for API and data orchestration.
AI-Driven Solutions: Beyond traditional full-stack development, I've been actively working with AI-powered applications. I've built AI agents and RAG-based chatbots using LangChain, LangGraph, vector databases, AI SDKs, and prompt engineering—integrating them into real products that deliver intelligent, context-aware experiences.
Automation & Workflows: I've developed automation workflows using tools like Windmill and Hyperbrowser to streamline processes and generate intelligent reports, helping teams work smarter and faster.
End-to-End Ownership: I've implemented authentication systems, integrated Stripe payments, designed database schemas, and contributed to architectural decisions—taking ownership of features from idea to production.
At my core, I enjoy solving real-world problems, learning new technologies, and building scalable, maintainable software that delivers actual value - not just code.
