As a Senior Full-Stack Developer, I led the end-to-end development of high-performance web applications. I utilized modern JavaScript frameworks like React, Next.js, and Remix for front-end design and implemented secure, scalable back-end services with Node.js and Express. Leveraging Prisma ORM with PostgreSQL and Sanity CMS, I ensured efficient data handling and dynamic content management. Collaborating with designers, product managers, and engineers, I translated business requirements into technical solutions prioritizing user experience and optimized performance.I also spearheaded the development of an AI-driven chatbot that utilized function calling and a vector database to deliver responsive, contextually aware interactions. Beginning as a proof of concept with OpenAI’s models, this chatbot evolved into a robust tool that supports model selection across options like OpenAI’s Gemini, Anthropic, Mistral, and Fireworks. The chatbot played a key role in the application by handling API interactions and using vector databases for enhanced response accuracy based on user history. Additionally, I utilized AI to fine-tune listings during data migration to Sanity, preserving continuity and improving engagement.My role included performance optimization, debugging, establishing coding standards, and mentoring junior developers. I led code reviews, contributed to architectural decisions, and implemented CI/CD pipelines to streamline release cycles. My technical contributions have enhanced site reliability, improved development workflows, and supported the product’s overall strategic goals.Key achievements included:- Architected and launched features that improved user engagement and streamlined processes.- Implemented continuous integration and deployment (CI/CD) pipelines to expedite and automate release cycles.- Enhanced site reliability by resolving critical issues and optimizing database interactions.
