I build scalable distributed platforms, reducing risk, latency, costs, and release time.

I've built high-impact engineering platforms at Goldman Sachs, AlphaSense, Bonfleet, BookMyShow, and Sandisk. At Goldman Sachs, I engineered a vendor risk optimization engine that surfaced the top 1% of high-priority risks and improved response times by more than 90%, while observability work reduced MTTR by more than 50%.

I've led teams from early startup engineering groups to 10-engineer squads, hiring, mentoring, shaping architecture, and delivering systems across fintech, enterprise SaaS, AI, and e-commerce. My hands-on work spans Java, Spring Boot, AWS, Kubernetes, microservices, distributed architectures, observability, and platform engineering, including projects that saved approximately $1M annually in cloud costs and $200K+ annually through enterprise integrations.
