About this gig

I will build high-performance FastAPI backends with Celery, Redis, PostgreSQL & AI integration (RAG / Llama)

Im a Systems-Oriented Backend Engineer specializing in FastAPI and scalable, production-grade systems.

I design and develop robust backends that are fast, secure, maintainable, and ready for real-world traffic whether you need a clean MVP or a complex AI-powered platform.

My Core Expertise:

  • FastAPI (Async, Pydantic v2, Dependency Injection, WebSockets)
  • Background task orchestration with Celery + Redis (queue isolation, retries, monitoring)
  • PostgreSQL, SQLAlchemy, Alembic (optimized schemas & migrations)
  • AI Integration & RAG systems (LlamaIndex, pgvector, Ollama, Agentic AI)
  • Security: JWT, RBAC, multi-tenancy
  • Docker, Docker Compose, microservices (gRPC), and reliability patterns

Notable Projects:

  • Engram High-performance RAG & Document Intelligence platform with sub-second vector search and zero data loss pipelines.
  • Phalanx (Aegis Risk) Real-time fraud detection engine with 66ms SLA, ONNX ML inference, and self-healing MLOps.

What You Get:

  • Clean, well-tested, documented code
  • Full source code + detailed README
  • Docker setup for easy deployment
  • Performance & security best practic

  • AI engine

    • Gemini
    • Llama
    • Langchain

  • Programming language

    • Python

I’m a systems-oriented Backend Engineer with a foundation in Mechatronics Engineering, focused on building reliable, production-grade digital systems. I specialize in FastAPI-based architectures, distributed task queues with Celery + Redis, and optimized PostgreSQL databases. My work includes AI-powered platforms such as RAG systems, vector search, and real-time ML risk engines. I design secure, scalable microservices using gRPC, JWT-based security, and reliability patterns like idempotency and circuit breakers to deliver clean, maintainable systems that perform under real-world load.
