Java / Spring Boot Backend Developer
I’m Youssef Saoud, based in Morocco. I build REST APIs and business applications with an emphasis on authorization, data integrity, and maintainable code.
Permissions, transaction boundaries, and data integrity are where I spend my attention.
My backend work connects REST APIs to real business workflows. I’ve worked with a development team on an internal CRM, and I build projects that make my engineering decisions inspectable.

Selected projects
Projects, vendors, and quotations.
One connected workspace.
A B2B platform with server-side role enforcement, invitation onboarding, and business workflows built on Spring Boot and PostgreSQL.
Spring Security enforces server-side roles and associate-scoped data access. Invitation acceptance locks the invitation and creates the account in one transaction. Email delivery remains a separate operation with manual resend recovery.

competing requests for stock
JWT-protected products, carts, and orders. Transactional checkout uses PostgreSQL row locks; order items retain their purchase prices.

API contracts. DTOs, Bean Validation, structured errors, and OpenAPI documentation.
Persistence. Atomic stock deduction, BigDecimal amounts, and ownership checks for carts and orders.
Verification. Unit, MVC, and PostgreSQL integration tests. Docker Compose supports local setup.
One database transaction
From repeated job listings
to a relevant review queue
A Python CLI that normalizes listings, scores relevance, and deduplicates by source ID and normalized content before local tracking.

Matching. Configurable search terms, keyword tiers, and dealbreaker rules.
Data processing. Shared job models, SQLite persistence, and content-based deduplication where enough text exists.
Useful output. Dry-run support, application tracking, and optional Telegram notifications. Scrapers depend on third-party source availability.
Technical writing
Decisions, tradeoffs, and the
details that make systems work.
Token lifecycles, transaction boundaries, and recovery when email delivery fails.
Authorization, financial totals, and the boundaries behind a business application.
Questions for reviewing permissions, concurrent requests, transactions, and failure recovery.
The three featured articles above and these five publications form the current writing collection. Each opens its original platform.
