Project details

I take a monolith or a messy pile of services and turn it into something you can actually deploy with confidence - Dockerfiles that build fast and stay small, docker-compose for local dev, and a CI/CD pipeline so pushing to main doesn't mean SSH-ing into a box at midnight. I've done this for teams moving off a single VPS and for ones already on Kubernetes who just need it done right. You'll get something a new hire could understand in an afternoon.

About Younes

Younes B.Status: Offline
Spring Boot Backend Engineer | Secure APIs, OAuth2/Keycloak, Fintech
Casablanca, Morocco - 1:32 pm local time
I build and secure Spring Boot backends for fintech and SaaS teams — OAuth2/Keycloak auth, payment flows, and APIs that survive a real pentest. Day job: secure banking microservices at a Moroccan bank. Nights: bug bounty hunter on HackerOne and Bugcrowd.

Most Spring Boot APIs I'm called in to look at fail on the same handful of things: refresh-token rotation misconfigured in Keycloak, IDOR on resource endpoints because authorization is checked at the controller instead of the data layer, JWT validation that trusts the alg header, and multi-tenant queries missing a tenant filter. I find these for a living on both sides — I write the code and I break it.

What I do:
- Spring Boot 3 / Java 21 REST APIs — clean domain modelling, virtual threads where they earn it
- Spring Security: OAuth2, JWT, Keycloak realms, RBAC, multi-tenant isolation
- Security review of an existing Spring codebase — OWASP API Top 10, written report with reproduction steps and patches
- Angular / Next.js front ends when you need one hand on the whole stack

Background: Senior engineer in a bank's digital factory, working on payment and fraud-adjacent microservices. Independent security researcher. Java/Spring core with Docker, Kubernetes, and CI/CD.

Send me your repo or your problem and I'll tell you straight whether I'm the right fit before you spend a dirham.
