What I'm looking for

I want to lead secure, cloud-native enterprise builds—modernizing platforms into reliable microservices, partnering in Agile teams, and owning architecture through full SDLC with strong observability, compliance, and maintainability.

I’m a Lead Full Stack Engineer and Solutions Architect with 15+ years of experience designing and delivering large-scale enterprise platforms across government, healthcare, and enterprise SaaS environments. I build secure distributed systems with scalable microservices architecture—focused on reliability, resilience, and long-term maintainability—grounded in domain-driven service design and event-driven processing.

I lead end-to-end full SDLC delivery, architecture planning, engineering mentorship, and technical decision-making in Agile environments. From Angular and modern SPA workflows to Java/Spring Boot backend platforms and API security (JWT, OAuth2, OpenID Connect), I modernize legacy applications into modular, cloud-native systems—turning high-volume, transaction-heavy workflows into maintainable, auditable solutions with strong operational observability.
