Nokia Murray Hill, NJ Jan 2026 - May 2026

Software Engineer

● Owned a production system end to end with zero documentation -- embedded with optical network engineers, extracted undocumented domain requirements, and delivered Java Spring Boot backend, React TypeScript frontend, and Oracle DB schema in 5 months; unblocked 5 stakeholder teams and eliminated an entire class of production errors across 1,000+ enterprise clients.

● Established typed API contracts, deterministic backend validation, automated contract test suite, and CI/CD pipeline from scratch -- converted informal domain knowledge into enforceable system behavior with zero-downtime deployment. Locomex Inc. New York, NY Jun 2025 - Dec 2025

Software Engineer

● Built production LLM pipelines on AWS Bedrock (Anthropic Claude) end to end -- designed agentic workflows, structured output schemas, automated KPI coverage checks, and eval harnesses; 50+ enterprise workflows automated per day with no human fallback across 10+ clients in a compliance-sensitive environment.

● Analyst review time cut from several hours to under 1 minute per workflow -- designed Aurora PostgreSQL schemas, FastAPI REST APIs, and React TypeScript dashboards as the full application stack; sub-1.5s response under 100+ concurrent enterprise sessions.

● Owned the product after shipping -- built observability dashboards, monitored system health, iterated based on real user feedback, and surfaced failures before clients saw them.

Dell Technologies Bangalore, India Oct 2021 - Aug 2024 Software Engineer II -- Technical Lead

● Technical lead for a distributed financial platform at 500K+ daily transactions -- owned architecture decisions and cross-team coordination across 150+ engineers; delivered a major modernization on a 6-month deadline reduced from 12 months, accelerating releases from quarterly to bi-weekly.

● Re-engineered backend hot paths for 37% throughput gain; introduced distributed caching cutting p99 latency approximately 70%. Led RCA on 15+ Sev-1 incidents, outages down 40%. Mentored 3 engineers into independent contributors.

● Established code review standards, automated test gates, and design documentation templates -- pre-release defect detection improved 25%; raised engineering standards across a 150+ engineer organization. Dell Technologies Bangalore, India Jul 2020 - Oct 2021 Software Engineer I

● Migrated 15+ legacy modules to C#/.NET and Java microservices with React TypeScript frontends and async event flows -- deployment frequency up 60%, latency down 22%; SQL query performance improved 23% through index optimization. KEY PROJECTS
