Hi, I’m Kolade 👋

Backend-focused engineer passionate about building secure, scalable, and production-ready backend systems. I enjoy designing clean APIs, working with async systems, and solving real-world problems with Python.


🧠 What I Do

  • Build backend services using FastAPI
  • Design authentication & role-based access control (RBAC)
  • Work with PostgreSQL, async processing, and background jobs
  • Structure codebases for maintainability and scalability
  • Integrate third-party services (payments, notifications, caching)

🛠 Tech Stack

  • Languages: Python, SQL
  • Backend: FastAPI, SQLAlchemy, Alembic, gRPC
  • Databases: PostgreSQL, Redis
  • Async & Background: Celery, Redis
  • Auth & Security: JWT, RBAC, OAuth (basic)
  • DevOps: Docker, Docker Compose, GitHub Actions, AWS
  • Testing: Pytest

🚀 Featured Projects

  • AI Document Intelligence Platform
    Backend system for document ingestion, processing, and async analysis.

  • E-Pharmacy E-commerce Backend
    Production-style backend with authentication, payments, order lifecycle, and notifications.


📌 Currently

  • Improving backend architecture and service boundaries
  • Building portfolio-grade, production-style systems
  • Preparing for remote backend engineering roles
