About

Your AI feature is stuck in a notebook. Mine are running in production. I'm an AI Backend Engineer who builds the systems that sit between your LLM and your users — the APIs, the pipelines, the databases, and the infrastructure that make AI actually work at scale. Currently, I'm the Founding Backend & AI Engineer at Hey Amara, where I single-handedly architected the entire backend for an AI-powered recruiting platform serving enterprise clients. No templates. No hand-holding. Just a problem and a deadline. What I built from zero: ✓ Multi-tenant PostgreSQL architecture with row-level isolation using Prisma ORM ✓ Agentic AI pipelines orchestrating LLMs for automated recruiting workflows ✓ Twilio-integrated SMS and voice communication systems ✓ Calendly-style scheduling engine — cut interview scheduling overhead by 60% ✓ Email signature detection module — improved parsing accuracy by 40% ✓ Staff Engineer-level security audit across 4 microservices — found 12 critical vulnerabilities, delivered a 30-page remediation report Previously: Security Operations at Riot Games (200+ cases resolved, 25% faster incident resolution) → Backend Automation at HJ Recruitment (saved 30% of ops team's manual processing time) → Full-Stack Delivery at Brandturn (shipped 2 weeks early, 99.5% uptime). Solo-built SORK — a production-grade multi-agent AI system using Anthropic Claude with 3 autonomous agents (Triage → Remediation → Verification). Published as an open-source npm package. What I work with: → Languages: TypeScript, JavaScript, Python (Intermediate), Java (Basic), SQL → Backend: Node.js, Express, FastAPI, REST APIs, GraphQL, WebSockets, Microservices → AI/LLM: Claude API, Groq API, LLaMA, LangChain, Multi-Agent Systems, RAG, Prompt Engineering → Databases: PostgreSQL, MongoDB, Redis, Pinecone, FAISS → Infrastructure: Docker, AWS (EC2, S3, Lambda, RDS), Vercel, Render, CI/CD → Security: JWT, OAuth 2.0, RBAC, API Rate Limiting B.Tech CSE at JECRC University (Kalvium Program) — 9.0 GPA. Top 20 among 3,000+ at national hackathons (MumbaiHacks, IIT Delhi). Open to AI Backend Engineer, Backend Engineer, or Full-Stack Engineer roles. Remote-first. Available immediately. → bhargavkalambhe3@gmail.com
