Executive Systems & Engineering Profile
Over seventeen years of hands-on professional software engineering, systems architecture, and DevOps leadership across high-growth startups, enterprise entertainment conglomerates, and Tier-1 financial institutions. Proven track record architecting high-throughput Node.js microservice meshes, resilient React single-page and server-side rendered applications, high-density transactional databases, and event-driven architectures.
Specialized expertise in modernizing legacy monoliths into distributed micro-apps, establishing zero-downtime CI/CD deployment pipelines, engineering fintech settlement disbursement workflows, and operating bare-metal Linux infrastructure managing multi-tenant cloud ecosystems. Strong advocate for Test-Driven Development (TDD), strict TypeScript contracts, and automated quality gates.
