πŸ’» Hi, I'm Lovepreet singh β€” Building Production-Grade AI & Backend Systems

AI Systems Engineer | Backend Architecture | Full-Stack ML

GitHub followers GitHub User's stars


🎯 About Me

I specialize in building scalable, production-ready systems that combine deep learning, backend engineering, and autonomous AI agents. My work spans:

  • πŸš€ Asynchronous Microservices β€” FastAPI, PostgreSQL, Redis task queues, Docker containerization
  • πŸ€– Autonomous AI Agents β€” Multi-step reasoning, RAG pipelines, tool routing, dynamic dependency injection
  • 🧠 Deep Learning β€” CNNs, LSTMs, Stable Diffusion, ControlNet, edge ML
  • πŸ” Production Systems β€” Biometric authentication, secure databases, idempotent operations
  • πŸ“Š Data Intelligence β€” EDA automation, ML inference, real-time processing

I believe in first-principles thinking: building things from the ground up to understand how they work, then optimizing for production.


πŸ† Featured Projects

πŸ”₯ Scalable Async Task Engine

FastAPI PostgreSQL Redis

scalable-async-task-engine β€” Production-grade async task processing microservice
A battle-tested pattern for handling long-running work (ML inference, ETL, email delivery) without blocking HTTP requests. Perfect for ML applications that need fast API responses + reliable background job execution.

# One-command setup
docker-compose up --build
# API on :8000, Worker running, Postgres + Redis included

πŸŽ“ Core Principles

  1. First-Principles Thinking β€” Build systems from scratch before reaching for frameworks
  2. Production-Ready β€” All code is architected for scalability, reliability, and observability
  3. Privacy-First β€” Prefer offline, local solutions when possible
  4. Asynchronous by Default β€” Non-blocking operations for responsive systems
  5. End-to-End Ownership β€” From data ingestion to deployment

πŸš€ What I'm Looking For

  • πŸ’Ό Backend/ML engineering roles where I can architect scalable systems
  • 🀝 Open-source collaboration on production-grade AI/backend projects
  • πŸ”¬ Innovation projects combining AI agents, distributed systems, and edge computing
  • πŸ“š Technical discussions on async patterns, RAG architectures, and ML infrastructure

πŸ’¬ Let's Connect

  • πŸ’» Explore my repositories β€” they're documented and runnable
  • πŸ“§ Reach out with questions, ideas, or collaboration opportunities
  • ⭐ If a project helps you, star it! (Feedback fuels improvement)

Building the future, one async task at a time.
