👨‍💻 About Me

I am a Software Engineering student at Adama Science and Technology University (ASTU) and an A2SVian (Africa to Silicon Valley) specialized in architecting high-performance backend services and production-grade AI/RAG platforms.

  • 🔭 Systems & Backend: Crafting concurrent distributed services in Go and high-throughput REST APIs in FastAPI/Python using Clean Architecture and Domain-Driven Design (DDD).
  • 🧠 AI & LLM Engineering: Building contextual knowledge assistants, agentic workflows, and semantic retrieval engines with LangChain, LangGraph, FAISS, and Sentence Transformers.
  • ⚡ Algorithmic Problem Solving: Solved 700+ algorithmic challenges across Codeforces, LeetCode, and HackerRank with an emphasis on graph theory, dynamic programming, and concurrency patterns.
  • 🎓 Leadership & Community: Creator of Tech With Hos, teaching software architecture, competitive programming, and backend engineering to over 1,000+ aspiring engineers.

🚀 Flagship Project Highlights

🤖 Hos AI — Enterprise RAG Platform

Hos AI Repo

A full-stack, enterprise-grade Retrieval-Augmented Generation (RAG) assistant that transforms documents (PDF, TXT, MD) into context-aware conversational AI with cited source attribution.

  • Impact: Sub-200ms vector search latency with FAISS and Sentence Transformers.
  • Security: JWT + Bcrypt authentication, CORS protection, rate-limiting, and SQLModel ORM.
  • Stack: FastAPI, Next.js 16 (Turbopack), PostgreSQL, FAISS, Docker Compose.

🛡️ CodeSentinel — AI Code Reviewer

Live Demo   CodeSentinel Repo

Automated AI-powered pull request & security auditor that scans codebases for vulnerabilities, logic bugs, AST anti-patterns, and test coverage gaps.

  • Impact: 90%+ precision on OWASP top vulnerabilities with line-level diff suggestions.
  • Features: Multi-model support (Claude / GPT-4o), interactive diff UI, analytics dashboard.
  • Stack: FastAPI, React 18, TypeScript, TailwindCSS, Docker, GitHub Webhooks.

⚖️ Go Load Balancer — Concurrent Reverse Proxy

Go Load Balancer Repo

High-throughput HTTP reverse proxy and load balancer written in pure Go featuring active background health checking, mutex-safe backend pools, and configurable retry policies.

  • Impact: Handles thousands of concurrent HTTP requests with zero-allocation round-robin routing.
  • Reliability: Automatic failover, exponential backoff retries, and comprehensive unit tests.
  • Stack: Go (Golang), Goroutines, Mutex Synchronization, GitHub Actions CI.

🏛️ Task Manager API — Clean Architecture

Task Manager Repo

Production-ready REST API built with Gin and MongoDB following Uncle Bob's Clean Architecture (Delivery, Usecase, Domain, Repository layers) with Mockery unit tests.

  • Impact: 100% decoupled business logic with JWT role-based access control (RBAC).
  • Testing: Comprehensive unit testing suite using Testify and Mockery mocks.
  • Stack: Go, Gin Framework, MongoDB Driver, JWT, Bcrypt, Mockery.
