Portfolio

IT Guy.
Project Driver.
Storyteller.

I build things, manage things, and document things — from API gateways to community pages. Based in Madagascar, collaborating everywhere.

About

I'm Rantsa.

A multi-faceted IT professional since 2015. I manage projects, ensure software quality, evangelize technology, and document everything I touch.

I'm language agnostic and all-in on vibe coding and agentic programming. I pick up whatever tool the job needs and adapt fast.

When I'm not in project mode, I'm out with my digicam documenting the streets of Antsirabe, growing a 26K-follower Facebook community called Inona no maresaka, or fumbling through harmonica riffs.

I'm not looking for a job — I'm looking for creative collaborators.

Work

Selected Projects

API Gateway

A middleware layer that wraps complex chains of billing and invoicing API calls into a single, clean HTTP endpoint. Think of it as a travel agent: you say "I want to go to Mexico," it handles flights, hotels, and city guides — and hands you everything in one bag.

Enabled Orange Madagascar to build satellite apps faster, without each team needing to maintain the full complexity of billing and invoicing services.

SoClean

A mobile app for evaluating the cleanliness of homes and rating cleaning service providers in France. Easy-to-use on mobile, paired with a web interface for reports and dashboards.

Replaced paper-based evaluation processes with smartphones, giving teams real-time insights and structured data.

Pushay

An intranet recognition tool that lets coworkers gratify each other for great work — democratizing top performer recognition. Led the full journey: mockup, project management, quality assurance, documentation, and specs.

Gave the team a fair, democratic way to recognize top contributors without relying solely on management.

NotebookApp

A minimalist photobook creation app — built to turn your best shots into a clean, shareable notebook. A personal side project born from a love of photography.

Personal project, publicly available.

Sabotsy Market Campaign

After the Sabotsy market fire devastated local merchants, launched a community campaign to support affected vendors and help them recover.

Provided visibility and support to merchants at a critical moment.
