What I'm looking for

I’m looking for a Full Stack role where I can build scalable Node.js/React systems and ship AI-powered features. I want strong engineering practices, fast feedback, and opportunities to mentor while optimizing performance and security.

I’m a Full Stack Developer with 2+ years of experience building scalable web applications. I bring deep expertise in Node.js, React, Angular, and AI-powered solutions, with a proven track record of delivering high-performance systems.

In my current role as Software Development Engineer II - Full Stack, I architected and delivered backend infrastructure for 4+ production applications using Node.js, Redis, AWS SQS, S3, and OpenAI APIs. I also developed Python-based AI microservices with LLaMA3 and Mistral to power semantic search and vector-based retrieval.

I lead meaningful parts of the product from end to end—handling complex frontend development (dashboards and data visualizations), implementing security and validation (SSO, reCAPTCHA v3, rate limiting, Joi/Zod), and automating backend operations with cron jobs and monitoring. I enjoy mentoring junior developers through code reviews and technical guidance, and I optimize user behavior tracking by integrating tools like PostHog and Google Analytics.
