GPU Utilization Optimization Platform
May 2026 - Present
  • Owned the frontend architecture while contributing to .NET backend services.
  • Implemented SSE-based real-time log streaming for low-latency observability of GPU workloads.
  • Built a client-side RBAC system to control access and actions based on user roles across the platform.
  • Automated API client and TypeScript type generation from OpenAPI specs, eliminating manual API sync issues between frontend and backend.
  • Set up testing infrastructure using unit tests, e2e and MSW, enabling reliable API mocking and smooth frontend development.
Internal Tools & R&D

  • Developed cross-platform developer productivity tools (Go backend, VS Code extension, Chrome extension).
  • Contributed to internal AI research initiatives and engineering prototypes for automation workflows.
  • Refactored legacy internal systems to improve maintainability and reduce technical debt.
Enterprise API Gateway & Extensibility Platform
Jun 2025 - Jan 2026
  • Developed an API gateway and transformation layer over multiple backend services, helping standardize authentication and external integration contracts.
  • Implemented transformation plugins and a Kafka-based event routing service to normalize payloads and route events to customer-defined functions.
  • Introduced OpenTelemetry instrumentation to track gateway overhead and simplify troubleshooting in production.
  • Built internal tools that reduced development overhead, including generation of API Gateway configs and SDKs from OpenAPI specifications.
Real-time Expense & Travel Management
Sep 2021 - May 2025
  • Improved ERP integrations (NetSuite, Sage Intacct, QuickBooks) with robust sync control and failure recovery mechanisms.
  • Centralized RBAC system using AWS Lambda authorizer and DynamoDB-based permissions model.
  • Designed configurable CSV/Excel export engine with dynamic schema support.
  • Built analytics pipeline using Tinybird enabling fast financial reporting on large datasets.
  • Implemented passwordless authentication (OTP email-based login), improving security and UX.
  • Established reusable NestJS backend foundation and infrastructure patterns using Pulumi.
