Software Engineer II · Backend & Platform · India

Systems that
cannot afford
to fail.

I build high-throughput backend systems and developer platforms that stay fast, reliable, and operable under real-world load. Currently at Temple; previously Zomato, Paytm, and BYJU'S.

Selected case studies

Evidence over adjectives.

A few examples of how I approach constrained, high-volume systems: understand the failure mode, simplify the path, and make the outcome measurable.

01

High-demand events at Zomato

ContextA homepage endpoint had to sustain dramatic traffic spikes without creating excessive infrastructure cost.

DecisionReworked the request path around local caching, payload optimization, and simpler service boundaries.

02

A checkout path built for speed

ContextThe District Events checkout workflow required a materially faster critical path as traffic grew.

DecisionOptimized backend processing across checkout, inventory, seat booking, and merchant payout workflows.

03

A platform for predictable releases

ContextFirmware rollouts needed durable workflows, clear rollout controls, and safe rollback decisions.

DecisionDesigned a release-management platform with Temporal orchestration and policy-driven promotion rules.

Experience

Built across products where reliability is the product.

Notes on engineering

Writing about the decisions behind the systems.

Architecture, distributed systems, and the principles that make complex systems easier to reason about.

Open to SDE II opportunities

Building something that needs to hold up?

I'm interested in backend, infrastructure, and platform roles where scale, reliability, and engineering judgment matter.
