Experience 7+ Years

Hands-on backend, platform, and distributed systems engineering across consumer tech, healthcare, aviation, and insurance.

Performance 4s

Turned an extremely slow, business-critical services flow into a fast, production-stable experience.

Operational Scale 7000+

Enabled large-scale monthly home visits through route optimization and workforce-aware scheduling systems.

Efficiency Gain 200 → 3

Reduced manual scheduling adjustments from 200+ per day to fewer than 3 via workflow automation.

About

I build backend systems that stay fast under pressure, remain observable in production, and scale with business complexity instead of collapsing under it.

What I bring

My work sits at the intersection of architecture, performance engineering, and delivery. I have led critical improvements in caching, memory usage, payload design, async workflows, and system reliability while working closely with product, operations, and engineering teams to ensure the platform delivers measurable business value.
