DevSecOps & Site Reliability Engineer
10+ years of progressive experience in enterprise infrastructure and DevOps engineering, specializing in financial services, securities trading systems, and cloud-native technologies. Expert in building resilient, secure, and scalable solutions for mission-critical applications.
About Me
I am a seasoned Lead DevSecOps Engineer with over a decade of experience in enterprise infrastructure and financial services. Currently serving as Lead DevSecOps at VFS Securities, where I architect and implement secure, scalable infrastructure solutions. Previously at SHS, I successfully re-architected product development processes and implemented cutting-edge cloud-native solutions.
My expertise encompasses AWS cloud platforms, Kubernetes orchestration, CI/CD automation, and financial technology solutions. I specialize in high-frequency trading systems, real-time processing, and enterprise-grade infrastructure supporting millions of transactions daily.
I am a Golang engineer specializing in GraphQL with gqlgen, gRPC, REST APIs, and event-driven systems. I deliver security-first, resilient cloud-native platforms (containers, Kubernetes) using Infrastructure as Code and SRE practices (observability, reliability, incident response, automation). Certifications: CEH, CCNP, CCNA. Bilingual collaboration across technical and business stakeholders.
