Daniel Romeo Mamphekgo / Data science / analytics

Data, software & the questions behind them.

I turn messy information into useful decisions—and build the software that makes those decisions easier to act on.

The person behind the projects / 02

A builder who likes the whole picture.

I’m a final-year Computer Science student and economics degree holder. My work brings an analyst’s curiosity to real products: how data is collected, queried, explained and turned into something useful.

I’ve tutored I.T. and Economics, which sharpened how I explain difficult ideas. Object Pascal is part of that teaching story: I used it mainly for high-school I.T., not as the centre of my professional stack.

Working knowledge

The toolkit / 03

From query to deployment.

01 / BUILD

Interfaces & systems

TypeScript, JavaScript, React, Next.js, NestJS, C#, ASP.NET Core, C++ and Qt.

02 / UNDERSTAND

Data & databases

Python, Pandas, NumPy and SQL across Oracle, MySQL and PostgreSQL; Firebase for NoSQL-backed publishing.

03 / DELIVER

Infrastructure & communication

Cloud deployment, API integration, testing, documentation and teaching what I learn.

Beyond the code / 04

Learning out loud.

I teach I.T. and Economics, share development lessons on YouTube and write about the ideas behind the work. The aim is simple: make useful things, then make them understandable.
