What I'm looking for

I’m looking to build secure, compliant AI + cloud systems (RAG, agents, microservices) and lead end-to-end delivery. I value strong engineering practices, CI/CD and observability, and teams that ship production-ready solutions in regulated domains.

I am a Senior Full-Stack & AI Engineer with 7+ years designing and delivering scalable, cloud-native applications across banking, healthcare, and education. I lead end-to-end development—from backend microservices (Java, Python, Node.js) to modern frontends (React, Next.js, Angular)—with a strong focus on technical leadership and production-ready outcomes.

I build AI-powered systems using Retrieval-Augmented Generation (RAG), embeddings, vector databases, and robust AI agents with schema validation and tool-calling. In recent work, I delivered AI-driven pipelines for script generation, text-to-speech, subtitles, and video synthesis, aligning RAG workflows to audio/video duration and deploying secure services on Azure & AWS.

I’m also known for crafting secure, compliant architectures for highly regulated environments. I apply strong security fundamentals (JWT/OAuth2/OpenID Connect/SAML, encryption with TLS/AES, OWASP best practices) and pair them with cloud expertise (Azure/AWS/GCP), event-driven messaging, and CI/CD/observability to help teams transform ideas into intelligent solutions.
