What I'm looking for

I'm seeking senior engineering roles building scalable, secure web and AI systems with cloud-native infrastructure, collaborative teams, and opportunities to mentor and drive measurable product impact.

I am a Senior Software Engineer with 11+ years building high-quality web, backend, and AI-driven systems. I focus on designing scalable, reliable, and secure architectures that meet both technical and user needs.

My recent work includes designing and delivering AI-enabled healthcare platforms and full-stack dashboards, developing production-grade payment SDKs and secure APIs, and integrating OpenAI and LangChain into backend workflows to automate complex processes. I routinely build cloud-native infrastructure on AWS and Azure, optimize real-time event processing with Kafka and Redis, and follow rigorous testing and HIPAA-compliant security practices.

I enjoy mentoring engineers across distributed teams, driving cross-functional collaboration, and solving hard problems that deliver measurable impact for users and businesses. I seek roles where I can lead technical execution, improve system reliability, and help grow engineering teams.
