IndiaWhat I'm looking for
I’m a Software Development Engineer at Walmart Global Tech, working on the Transactions / Payments Platform. I’ve architected performance and reliability improvements under heavy load—eliminating thread starvation and deadlocks, raising per-pod capacity, and meeting a Jan 2026 regulatory deadline with zero production defects at launch.
I also build scalable automation and platform components: distributed config-override for test isolation, multi-tenant regression automation that cuts validation time from 30–40 minutes to ~3 minutes, and payment eligibility/state-driven architecture across checkout and payment microservices. My approach blends system design, rigorous testing, and observability to ship dependable services.
