👋 Hi, I'm Samuel Ojetunde

AI Engineer · Data Science Student · Open Source Contributor

I build AI-native software, automate the data pipelines that feed it, and ship in the open.

🧭 About Me

I started out in Pharmaceutical Technology (National Diploma, Distinction) before pivoting fully into tech. Since then I've moved through financial-data automation, credit-risk analytics, and now full-stack AI-native software engineering — currently studying Data Science at MIVA Open University while working as an AI Fullstack Engineer and AI Software Intern.

Every stop on that path — data analytics, backend engineering, open source — feeds the same goal: scaling deep into AI/ML while staying strong as a well-rounded software engineer.

  • 🔭 Currently building production tools in Python, Go, React, and NestJS
  • 📊 Background in SQL, Power BI and financial data analytics
  • 🎓 Studying Data Science at MIVA Open University
  • 🌱 Actively contributing to open source since March 2026
  • 🤖 Deeply invested in AI-native development & prompt engineering — using LLM-assisted workflows to ship faster and reason through hard problems
  • 💬 Ask me about SQL automation, Go, Power BI, or AI-native workflows

💼 Professional Experience

Junior AI Fullstack Engineer — Secondary City Tech (Remote, Ogun, Nigeria) · Mar 2025 – Present

  • Refactored a 3-slot image uploader into a single multi-file uploader with previews, memory cleanup, and upload-limit enforcement
  • Traced and verified the full upload pipeline: React → NestJS controller → FilesService → S3
  • Debugged and resolved AWS S3 connectivity and credentials configuration issues
  • Diagnosed environment-variable validation failures blocking the frontend from starting

AI Software Intern — Learn2Earn (Hybrid, Lagos, Nigeria) · Nov 2025 – Present

  • Built production-grade tools and CLI applications as part of an AI-native engineering program
  • Developed backend logic and data pipelines in Go, applying concurrency patterns, file I/O, and modular package design
  • Integrated LLM-assisted workflows into backend and CLI development, accelerating debugging cycles and strengthening code reasoning

Data Analyst Intern — Qucoon Academy (Hybrid, Lagos, Nigeria) · Aug 2025 – Nov 2025

  • Streamlined financial reporting for Stanbic IBTC by engineering automated SQL workflows, replacing manual Excel-based processes
  • Executed data modeling and analytical reasoning to uncover actionable insights for high-level business decisions
  • Collaborated cross-functionally to translate raw financial datasets into clear, interactive dashboards
  • Optimized data transformation processes and SQL scripts, improving reporting speed and accuracy

🚀 Featured Work

⚡ Financial Securities SQL Automation Reporting for Bonds, OMO, and Treasury Bills was trapped in manual Excel sheets, causing high latency and errors. I engineered a robust SQL Server ETL pipeline to centralize fragmented security data — cutting reporting turnaround from hours to seconds and significantly improving data integrity. → Explore the SQL architecture

🎯 ABZ Limited — Credit Risk & Loan Analytics Investigated a surge in loan defaults within a micro-lending portfolio. Built an end-to-end Power BI suite using DAX and Power Query to segment borrower risk — surfacing unexpected default trends in mid-grade borrowers (B, C, D) that led to a refined credit strategy. → Explore the analytics case study

⛓️ Invofi A decentralised invoice-financing protocol built on Stellar Soroban, letting businesses unlock liquidity against unpaid invoices on-chain. Built as part of the Stellar-VaultLink team. → View repository

🧩 Logic in Go (Piscine-Go) Pure-logic Go exercises with no external libraries — a recursive Sudoku solver for 9x9 grids, plus Quad and Quadchecker, tools that render and identify geometric patterns from coordinate data. → View repository

🎓 Academ A responsive student portfolio and academic management site — homepage, project showcase, an interactive task planner with localStorage persistence, and a validated contact form. Built with hand-written HTML5, CSS3, and vanilla JavaScript. → Live site · → Repository

🌍 Open Source Contributions

Since March 2026 I've been an active open source contributor — ongoing — using AI-assisted, prompt-engineering-driven workflows to quickly ramp up on unfamiliar codebases and ship real contributions. Most of that work sits across Go and TypeScript projects in the Stellar / Soroban ecosystem (smart contracts, protocol frontends, and DeFi tooling).

🗓️ Contributing since March 2026 (ongoing)
🍴 Repositories forked / contributed to 77+
🧱 Primary stacks Go, TypeScript, Soroban/Rust contracts
🌐 Primary ecosystem Stellar / Soroban (DeFi & fintech tooling)
