Sena Abebe, software developer, Addis Ababa

I simply build: the frontend, the backend, and everything in between.

A software developer based in Addis Ababa. I build with Go, TypeScript, and Next.js, with an active focus on improving AI for low-resource languages and developing custom agents.

About

Who am I.

What do I do?

Most of my time is spent building backends in Go, crafting thoughtful UIs, improving AI on low-resource languages, and developing custom agent systems.

What I care about

I'm a fan of clean code and thoughtful design. I try to keep things simple and avoid overcomplicating problems just to look smart.

The promise

I build stuff that moves the needle. No fluff. If it doesn't add value, it's not getting built. It's as simple as that.

Experience

Where I build.

2025 — PresentCurrent role

Currently working as a Full Stack Developer at Jirtuu Software Labs

Engineering full-stack web applications, designing retrieval-augmented generation (RAG) architectures, and building resilient data pipelines.

Full Stack Architecture

Building responsive, production-grade applications with modern web frameworks and reliable backend runtimes.

RAG Systems

Designing retrieval-augmented generation systems, semantic search flows, and context retrieval pipelines for production.

Data Pipelines & Ingestion

Engineering high-performance ingestion pipelines and backend workflows optimized for speed, reliability, and scale.

Work

Selected works.

A selection of my best work. Products, developer tools, and the occasional terminal obsession.

Aeon

Productivity

An all-in-one student organization tool that keeps planning, tasks, and deadlines in one place. Uses an internal custom agent built with Golang to automate scheduling and streamline academic workflows.

Folio

Desktop app

A fast, distraction-free document and presentation reader for Linux built to handle a broad range of formats, from everyday documents to non-conventional office files and slide decks, without launching heavy office suites.

iwgtk

System tool

A wireless networking GUI for Linux sitting on top of iwd. Forked and redesigned with GTK4 and Libadwaita for a modern, streamlined desktop interface.

ghstat-go

Developer tool

A high-performance CLI tool built in Go that summarizes GitHub contributions directly in the terminal. Fast, reliable insight into repository activity via the GitHub GraphQL API.

Monkeytui

CLI

A terminal tool influenced by Monkeytype. I like typing tests and I prefer terminals to GUIs, so I built a tool that brings the two together.

Jijira

Browser extension

Jijira scans any webpage you're on and converts every price to your currency of choice, right where it sits. No switching tabs, no mental math.

Unisocket

Tooling

A networking tool that displays detailed information about current connections. Built with Go and Bubble Tea, because CLIs should look as good as they perform. Works on Linux, macOS, and Windows.

Stack

What I work with.

Things I've spent thousands of hours on. I'm pretty good at these, and I'm working on many more.

Backend

Go

Where most of my backends start. Concurrent, compiled, and straightforward to ship.

Frontend

React

Component-based UIs. Still the default when I'm building for the browser.

Language

TypeScript

Types on the JavaScript I already write. Fewer surprises later.

Frontend

Tailwind

Utility classes next to the markup. Fast to iterate, easy to keep consistent.

Framework

Next.js

React with routing, rendering, and a production setup I don't have to invent.

Backend

Node.js

JavaScript on the server for APIs and tooling that don't need Go.

Data

PostgreSQL

Relational data with constraints I can actually rely on.

Design

Figma

Layouts and systems, worked out before they become components.

Language

Python

Scripts, glue, and anything that needs to exist before I reach for Go.

API

GraphQL

A typed schema instead of a scatter of REST endpoints.

Infra

Docker

Same runtime locally and in production. Fewer environment surprises.
