Work Experience

Software Development Engineer Intern

Refold AI

Dec 2025 - Present Bangalore, India
  • Built an adversarial evaluation harness for the workflow-builder agent, generating up to 20 edge-case scenarios per tool across 8 failure modes; auto-runs on every PR via Jenkins, LangSmith/Langfuse to catch agent regressions before merge.
  • Delivered the SAP Ariba procurement integration end-to-end (SOAP/WSDL, REST/gRPC) with 3 authentication methods and procure-to-pay (P2P) flows; resolved per-realm WSDL namespace conflicts to unblock a key enterprise demo.
  • Engineered a Model Context Protocol (MCP) server exposing the platform as 10+ agent-callable tools via REST, gRPC, and GraphQL interfaces, enabling Claude and other LLM agents to drive workflows programmatically.
  • Developed AI agent capabilities on a Python/FastAPI+ LangGraph service — token-budgeted memory, resumable streaming, and hybrid semantic + keyword retrieval (RAG) over 3072-dim embeddings across 214+ connectors.
  • Deployed services on AWS(EC2, S3) with Docker/Kubernetes, instrumented with Prometheus, Loki, and Jaeger; cut startup memory footprint 77% (1467 MB → 343 MB) by lazy-loading connector schemas.

Software Development Intern

Bluestocks Fintech

Jun 2025 - Aug 2025 Remote
  • Built backend REST APIs that stream live stock-market data to the user dashboard over WebSockets, powering the platform’s live IPO and market-data features with updates pushed the moment the market moves.
  • Designed an event-driven pipeline that broadcasts upstream market changes to clients over a persistent WebSocket connection — no client-side polling — cutting end-to-end latency and keeping dashboards live as prices shift.
  • Engineered REST endpoints and PostgreSQL schemas backing the feed, and partnered with frontend engineers to integrate and ship the live data feature ahead of launch.

Projects

Meta-Presence – Real-Time Metaverse Platform for Events

View Project
TypeScriptAngularNode.jsWebSocketsWebRTC
  • Built a 2D virtual-office metaverse where distributed teams join a shared space, move avatars across a canvas, and collaborate in real time, with a TypeScript/ Angular client recreating in-office presence remotely.
  • Architected the real-time layer in TypeScript/Node.js using WebSockets for avatar movement and WebRTC for peer-to-peer voice/video that activates by proximity as users move near each other.
  • Scaled concurrent rooms with interest management (spatial culling) — broadcasting each user’s position only to nearby peers with batched, rate-capped deltas — cutting socket fan-out from O(N2) toward O(N).
