Rejwanul Hoque

Backend Engineer/India

I build backend systems that stay fast and correct under load: API gateways, retrieval pipelines and multi-agent services, mostly in Go and Python.

Final-year CSE student at IIIT Sri City. Most recently an SDE intern at ASOasis Tech, where I shipped an AI interviewer and a sandboxed code-execution engine in Go on AWS. I care about measurable performance, clean failure modes and tests that catch real bugs.

Experience

  1. SDE Intern at ASOasis Tech

    Oct 2025 – Jul 2026 · Remote

    • Delivered the AI interviewer and a sandboxed code-execution engine for CareerVerse, an ed-tech platform serving 1,000+ users, using Go, AWS and Next.js.
    • Designed the matching engine with the product team for an AI-persona dating app with 100,000+ downloads on the Play Store.
    • Owned the scraping infrastructure: headless Chromium on Go-based AWS Lambda, cron-orchestrated for periodic extraction from trading platforms.
    • Architected the CRM's PostgreSQL schema for observability and integrated Stripe payments via Supabase Edge Functions.
    • Drove adoption of AI-assisted development across the team, using prompt and context engineering with Claude Code, Cursor and Antigravity to cut token costs without lowering quality.
    • Go
    • AWS Lambda
    • PostgreSQL
    • Supabase
    • Stripe
    • Next.js

Projects

goGate

Distributed API gateway

  • Dynamic routing, load balancing, circuit breaking and rate limiting, sustaining 10k–24k+ req/s at P99 <15ms across 3,000+ concurrent users.
  • Runs on a production VPS behind Caddy with GitHub Actions CI/CD and Prometheus/Grafana dashboards. Load-tested with k6.
  • Go
  • Redis
  • Docker
  • Prometheus
  • Grafana
  • Caddy

ClauseGuard

Multi-agent contract auditing & redlining

  • Orchestrator, Auditor, Redliner and Critic agents on Strands Agents SDK and Amazon Bedrock audit vendor contracts against a legal playbook served over MCP, then return a redlined .docx for a lawyer to approve.
  • Deterministic OOXML engine writes native Word tracked changes; the LLM only emits structured edit intent and never touches document XML.
  • A Critic agent re-fetches every cited clause, so each finding ships with evidence, a citation and a confidence score. Per-contract FAISS indices prevent cross-contract leakage.
  • Python
  • Strands Agents
  • Bedrock
  • MCP
  • FAISS
  • FastAPI
  • SQLAlchemy

Reed

Agentic RAG system

  • Production RAG backend with FastAPI and SSE streaming, holding time-to-first-token at 1.5s under concurrent load.
  • Self-correcting retrieval (ChromaDB, BM25 reranking, LLM grading) that removes 60% of noisy context before generation.
  • Python
  • FastAPI
  • LangGraph
  • ChromaDB
  • BM25
