I build software
from product idea
to working system.
Junior Software Engineer at Reality Sports and 2026 software engineering graduate from INSAT. I build backend services with Java and Spring Boot, full-stack product features, PostgreSQL and GraphQL APIs, event-driven integrations and AI/LLM-powered applications.

01 / ABOUT
Engineering with
product context.
I’m Houssem Sahnoun, a software engineer at Reality Sports and a 2026 software engineering graduate of INSAT. My core is backend development with Java and Spring Boot, working across PostgreSQL, GraphQL and REST APIs.
At Reality Sports I have worked on real product features end to end — match, tournament and payment workflows, an event-driven notification system on AWS SNS/SQS and Firebase Cloud Messaging, and an AI-powered matchmaking system built around language models. Before that, I shipped full-stack and AI work at MAZ-DEV and CED Tunisia. I like pragmatic designs, solid domain logic and software that holds up beyond the demo.
