Where I've Worked

Experience

Akvelon, Inc.
Software Development Engineer · May 2021 - Present · Remote

Worked on several client and internal projects - from product features and integrations to internal tools and platform work. Involved in technical research, RFCs, and solution design beyond just implementation.

Internal Tools & R&D
Jan 2026 - Present
  • Developed an Azure DevOps workflow enriching task descriptions via Azure Functions and RAG-based processing.
  • Built a cross-platform time-tracking tool for developers using Go, a VS Code extension, and a Chrome extension.
  • Researched AI agent capabilities and prepared technical project ideas for intern mentorship.
  • Improved reliability of internal projects through refactoring and technical debt reduction.
Enterprise API Gateway & Extensibility Platform
Jun 2025 - Jan 2026
  • Developed an API gateway and transformation layer over multiple backend services, standardizing auth and integration contracts.
  • Implemented transformation plugins and a Kafka-based event routing service for payload normalization.
  • Introduced OpenTelemetry instrumentation to track gateway overhead and simplify production troubleshooting.
  • Built internal tools for generating API Gateway configs and SDKs from OpenAPI specifications.
Real-time Expense & Travel Management
Sep 2021 - May 2025
  • Improved ERP integrations with NetSuite, Sage Intacct, and QuickBooks - manual sync controls, pause functionality, better error handling.
  • Centralized RBAC into a dedicated Lambda authorizer backed by DynamoDB-stored roles and permissions.
  • Reworked a hardcoded CSV/Excel export flow into a configurable system with custom columns and ordering.
  • Developed travel expense analytics using Tinybird and pre-aggregated views for fast reporting on large datasets.
  • Replaced legacy password auth with passwordless OTP email login, improving security and UX.
  • Established a reusable NestJS foundation for new backend services, including shared libraries with Pulumi.
