Machine Learning Expert. Back End Developer. Teacher.
Hi, I'm Allan. I build back ends, train models, and explain both without making you cry.
Founder of Scape AI and Scape Data Solutions. Machine learning is my specialty, Django back ends are my daily bread, and teaching keeps me honest. From Sirisia, Bungoma to a Toptal profile.
The short version
Allan Simiyu Waliaulah grew up in Sirisia, Bungoma, studied mathematics at Machakos University, and completes his master's in Financial Engineering at WorldQuant University in November 2026. He is a consultant on Toptal, runs Scape Data Solutions as Managing Director, and founded Scape AI.
He is a machine learning specialist, a back end developer and a teacher, and has worked in finance, telecoms and tech. The thread through all of it is simple: take a messy pile of data, make a model that works, and ship it so someone actually uses it.
- Born in Sirisia, Bungoma.
- Speaks English and Swahili, and Python.
- Maths graduate who now argues with matrices for a living.
- Started a company in 2020, then another: Scape AI.
- Still finds a clean dataset more satisfying than a sunset.
What I'm best at: machine learning
Recommender systems
My favorite. "People who bought this also bought that" is basically mind reading with a spreadsheet. I built an item-to-item recommender from views, carts and purchases, and it skips what you already bought.
Computer vision
Computers are bad at seeing. I know, because I spent years drawing boxes around bikes, shelves and scans to teach them. Now I build with OpenCV and PyTorch.
Language and text
Cleaning messy text, tagging it, and making sense of it with spaCy, NLTK and LLM fine-tuning.
Models that touch money
Credit scoring, fraud flags, forecasting. When a model is wrong here, someone notices fast.

Back end developer, properly
APIs and services
Django and REST back ends built to be used by real apps. Scape Data Intelligence powers lead generation, data enrichment, property intelligence, jobs, projects and user management.
Money logic
CashSpace covers the full loan lifecycle: applications, credit workflow and repayments, on Django, PostgreSQL and REST.
Databases and data pipelines
PostgreSQL, MySQL, Supabase, Firebase, Azure Data Factory and Microsoft Fabric, so the data arrives clean and on time.
Shipping it
Vercel, AWS, Cloudflare, Terraform, Git and Linux. If it works on my laptop, I make sure it works on yours too.

Why I teach
Every model I build has to be explained to someone. Tutoring is where I learned to do that without anyone crying.
