About

Hi, I’m Franck Adonis (Tchowa Franck) — a software engineer and computer science teacher who enjoys building reliable software and sharing what I learn along the way.

My main focus today is backend development with Elixir and the Phoenix ecosystem, where I design APIs, real-time applications, and systems that stay simple even as they scale. I’m particularly interested in the strengths of the BEAM platform: concurrency, fault tolerance, and maintainability.

Over the years I’ve worked on a variety of products including university platforms, marketplaces, messaging systems, and billing/invoice applications. I enjoy collaborating with designers, product teams, and stakeholders to turn ideas into software that people actually use.

Before specializing in Elixir, I worked with several other technologies across the stack, which helped me develop a broad perspective on software architecture and product development.

This blog is where I share my experiences building real-world systems, mostly about Elixir, backend architecture, and practical engineering lessons.

My Tech Stack

Backend

APIs & Data

Frontend

Tools

I’ve also built projects using Laravel, Node.js (Express, Socket.io), and Electron.

Technologies I’ve experimented with or used in smaller projects include Go, Java, C/C++, Flutter, and Docker.

Design & Product

Besides coding, I enjoy the product side of software. I can create basic UI wireframes and mockups using tools like Adobe XD and Illustrator, which helps when collaborating with designers or shaping early product ideas.

What I’m Learning

Technology evolves quickly, and I try to stay curious while being selective about what I learn.

Areas I’m currently interested in include:
