Work Experience

Backend Engineering Intern

OpenStreamLabs

Nov 2025 - Mar 2026
  • Built REST APIs and asynchronous worker pipelines using Redis and Celery to support automation and data processing workflows
  • Optimized MongoDB aggregation queries and indexing strategies, reducing average response latency from 420ms to 110ms
  • Implemented retry handling and fault recovery mechanisms for concurrent background processing, reducing duplicate side effects
  • Developed integration tests covering core API workflows to improve backend reliability and reduce regression issues

Projects

SecureLens

View Project
FastAPIhttpxOpenAIRAGDocker
  • Built 3-phase orchestration pipeline (triage concurrent scanning LLM reasoning) processing multiple repositories in parallel; median scan time under 2 minutes
  • Engineered async scanning service using FastAPI + httpx, executing 30+ security checks (TLS, headers, cookies, exposure) concurrently per target
  • Integrated OpenAI RAG pipeline to convert structured scan results into human-readable risk narratives, enabling actionable reporting
  • Secured APIs with rate limiting, SSRF protection, and Dockerized deployment; validated on 50+ websites in internal trials

Sentinel

View Project
RedisCeleryJWT
  • Architected uptime monitoring system using Redis-backed Celery workers for low-latency background event processing and scalable monitoring execution
  • Implemented idempotent webhook dispatching with retry budgets and dead-letter handling to reduce duplicate and failed alert deliveries
  • Built multitenant JWT authentication and exposed health/metrics endpoints for observability; designed retry budgets to prevent cascading failures

LedgerDB

View Project
MongoDBJWTBcryptMongoose
  • Engineered a double-entry style ledger with immutable append-only entries (no updates/deletes) to ensure a fully auditable financial trail
  • Implemented idempotent transactions using unique idempotency keys stored alongside transfers, guaranteeing zero duplicate processing under concurrent requests
  • Designed JWT-based authentication with Bcrypt hashing and role-based access control for account management, admin operations, and transactional security
  • Optimised MongoDB schema and aggregation pipelines for high-concurrency workloads; leveraged Mongoose middleware for data integrity enforcement
