Backend & AI EngineeringAngushylesh Subburaj

I build production-grade backend systems and AI-integrated APIs for early-stage startups fast.

What I deliver:

REST APIs & microservices in Java (Spring Boot), Python, or Go

LLM/RAG integrations using LangChain4j, Spring AI, and OpenAI APIs

AWS deployments (EC2, RDS, S3, Lambda, ECS) with Docker/Kubernetes and CI/CD via GitHub Actions

Vector database setups (pgvector, Supabase) for semantic search and AI features

Kafka/RabbitMQ event-driven architectures

Past work includes:

Founding engineer scope at an AI2 Incubator-backed SaaS startup (Suede) shipped auth, onboarding, and dashboards across 50+ zero-downtime deploys

NLP backend at MQuotient processing PDFs at 95% accuracy, 40% faster than manual

AWS CLI observability tool aggregating EC2/EBS/ELB/S3 metrics

Best fit for: startups that need a backend or AI engineer who can own features end-to-end, not just execute tickets.
