Senior Full Stack EngineerAI/ML EngineerSoftware Architect

👋 Hi, I'm Alabi Joshua Olufemi—a Senior Full Stack Engineer and AI Engineer with over 5 years of experience building production-ready, AI-powered SaaS platforms that serve 100,000+ users globally.

What I Do: Full Stack & AI Engineering

I specialize in full stack development using JavaScript, TypeScript, React.js, Node.js, NestJS, Python, and FastAPI. My work spans the entire software lifecycle—from architecting scalable backends with MongoDB, PostgreSQL, and AWS to crafting responsive frontends with React Native and Electron.

On the AI side, I build intelligent systems powered by Large Language Models (LLMs), vector embeddings, prompt engineering, and reinforcement learning with human feedback (RLHF). I've optimized AI models to boost accuracy by 25% while reducing compute costs by 15%—real engineering, not just hype.

Impact-Driven Projects

• Podus AI (Legaltech): Built a multi-platform legal assistant (web, WhatsApp, mobile) serving 50,000+ active users in Nigeria, automating legal research and reducing case review time by 50%.
• Lightforth AI (Career Tech): Engineered AI-driven resume optimization, automated job applications, and interview simulators that improved job placement efficiency by 70% for 20,000+ users.
• Gmind AI (EdTech): Designed offline-first, multilingual AI tutoring tools for underserved African communities, enabling voice-powered learning in low-bandwidth environments.
• Justice Clock: Developed an AI-powered judicial case tracking system adopted by Nigerian Ministries of Justice.
