# Kudzai Prichard Matizirofa

> AI / ML Engineer · Co-Founder of Teleagents & OurAfrica. AI / ML Engineer and two-time co-founder. I co-founded Teleagents, which builds voice AI agents for Africa on its own speech models for Shona, Ndebele and Ndau (Champion, POTRAZ Innovation Expo & Conference 2026), and OurAfrica, an offline-first learning platform on web, desktop and Android. My engineering spans machine learning, computer vision, NLP, speech and LLMs: I train models, deploy them behind APIs on AWS and Azure, and run them in production. At Sybrin I built document-AI and banking systems for EcoCash, CABS, Stanbic, BancABC and Old Mutual. As a founder I own the product end to end, from strategy, go-to-market and client work to architecture and code. I hold a B.Sc. Honours in Artificial Intelligence & Machine Learning from the University of Zimbabwe.

This site is a terminal-style portfolio. Everything below is also on the page; a plain, no-animation view is available with the `--no-tty` switch. AI agents in browsers that support WebMCP can use the tools this page registers (download_resume, navigate_to_section, get_repo_stats, send_message).

## Projects

- [Whiteboard Studio](https://prichard.co.zw/projects/whiteboard-studio): Whiteboard explainer videos teach well, but making one means drawing, animating and timing every element to a voiceover by hand, and most tools end up looking like clipart. Stack: TypeScript, Electron, React, MCP, Kokoro TTS, SQLite, Vitest. Download (Windows installer): https://github.com/kudzaiprichard/whiteboard-studio-releases/releases/latest
- [Anvil](https://prichard.co.zw/projects/anvil): Interview-prep sites hand you a wall of random problems and an AI helper that does the thinking, so the pattern recognition an in-person interview tests never gets built. Stack: Rust, Tauri 2, Next.js, React, TypeScript, SQLite, CodeMirror. Code: https://github.com/kudzaiprichard/anvil Download (Windows, macOS & Linux): https://github.com/kudzaiprichard/anvil-releases/releases/latest
- [METIS](https://prichard.co.zw/projects/metis): Type-2 diabetes guidelines give general rules, but the best medication for a specific patient is often unclear: dozens of clinical features interact. Stack: Python, PyTorch, FastAPI, PostgreSQL, Neo4j, Next.js, React. Code: https://github.com/kudzaiprichard/metis
- [AURA](https://prichard.co.zw/projects/aura): Phishing emails reach the inbox, and a detection model that never hears whether it was right slowly goes stale. Stack: Python, FastAPI, scikit-learn, PostgreSQL, Next.js, TypeScript, Docker. Code: https://github.com/kudzaiprichard/aura
- [IndabaX 2026: Loan Default](https://prichard.co.zw/projects/loan-default-prediction): The Deep Learning IndabaX Zimbabwe 2026 hackathon challenge: predict which loans in Zimbabwe's banking sector will default, when the test data comes from a different time period than the training data, so ordinary validation scores are optimistic. Stack: Python, LightGBM, CatBoost, XGBoost, Optuna, PyTorch, Modal. Code: https://github.com/kudzaiprichard/loan-default-prediction Result: Public leaderboard AUC 0.6840; private leaderboard AUC 0.6878.
- [Sentinel](https://prichard.co.zw/projects/sentinel): Investigators work across separate records, photos and maps, so matching a face to a known suspect or seeing where crimes cluster is slow, manual work. Stack: Python, InsightFace, OpenCV, scikit-learn, PostgreSQL, pgvector, Gemini, Flask. Code: https://github.com/kudzaiprichard/sentinel
- [OurAfrica](https://prichard.co.zw/projects/ourafrica): Learners across Africa often pay a lot for slow, unreliable data, and most learning platforms assume a fast connection that is always there. Stack: Spring Boot, Next.js, Tauri, Rust, Kotlin, Jetpack Compose, PostgreSQL, AWS. Website: https://ourafrica.co.zw Download (Android APK): https://github.com/kudzaiprichard/ourafrica-android-releases/releases/latest/download/ourafrica-android.apk Download (Desktop apps): https://github.com/kudzaiprichard/ourafrica-releases/releases/latest
- [UBot MT4](https://prichard.co.zw/projects/ubot-mt4): Following a trading strategy by hand is slow and inconsistent; an automated system can apply the same rules to every tick. Stack: MQL4, MetaTrader 4, Algorithmic Trading, Expert Advisor. Code: https://github.com/kudzaiprichard/ubot-mt4 Result: In the MetaTrader strategy tester (every-tick model), the backtest balance roughly doubles, from about 500 to about 990, over about 44 trades.

## Experience

- Co-Founder & AI Engineer @ Teleagents (2025 - Present): Co-founded Teleagents to build human-sounding voice AI agents for African languages — inbound support, outbound sales and 24/7 call-centre automation — on our own speech models and self-hosted infrastructure. In closed beta with enterprise clients across Zimbabwe, and named Champion at the POTRAZ Innovation Expo & Conference 2026.
- AI Systems Engineer @ Sybrin Imaging Solutions (Aug 2024 - Jul 2026): Enterprise fintech company serving tier-1 African banks and insurers — EcoCash, CABS, Stanbic Bank, BancABC and Old Mutual — across 6+ markets. Owned the full delivery loop: AI system design, cloud deployment on AWS and Azure, ML model integration and live client delivery.
- Co-Founder & Engineer @ OurAfrica (2025 - Present): Co-founded OurAfrica, an offline-first learning platform (LMS) for low-bandwidth learners and organisations across Africa. I built and run all of it: the Spring Boot API, a Next.js web app that also ships as a Windows desktop app, a native Android app, and the AI tooling that produces the courses. Learners download a course, study for days without a connection and sync their progress, quizzes and certificates when they are back online.
- Software Engineer Intern @ Replica Systems (Jan 2022 - Jun 2022): Industrial attachment delivering a full-stack site-management platform for a construction client, and taking ownership of production websites including the Replica Systems corporate site.
