I work where identity governance meets real software engineering.
- 🔐 IAM Consultant at Smpl ID, implementing SailPoint IdentityIQ for a leading Egyptian bank — provisioning workflows, custom BeanShell rules, AD/Exchange integration and LiveReports
- 🏗️ I also build and operate a production learning platform end to end — Spring Boot + React, six permission roles, device-bound auth, real-time updates, Dockerised deploy

The engineering habit is what makes the IAM work better — tracing a JasperReports failure on WebLogic to deployment-cache corruption is root-cause debugging before it's IAM.

🎓 SmplID Learning Platform — production LMS (Spring Boot + React)
A learning platform in daily production use, built and operated end to end.
- Access control: six roles (admin, course moderator, instructor, mentor, and two student types) enforced server-side on every request
- Exam integrity: device-bound student login via a companion Windows agent, single-active-session enforcement, watermarked course material, screen-capture detection
- Real time: notifications and messaging over server-sent events on a single shared connection
- Performance: cut the initial JS payload 64% (1.21 MB → 382 KB) with route-level code splitting; indexed 73 foreign-key columns Postgres leaves unindexed
- Delivery: GitHub Actions CI, images to GHCR, Docker Compose behind Caddy with automatic HTTPS, Flyway migrations applied on boot
- Stack: Java 21, Spring Boot 3, Spring Security, PostgreSQL 15, Flyway, React 19, Vite, Tailwind, Docker, Caddy, Nginx
Private repository — company product. Happy to walk through the architecture.

Move generation is verified with perft: the engine reproduces the published node counts for the starting position exactly (20 / 400 / 8902 / 197281), which is what proves castling, en passant and promotion are all handled correctly. Read the engine.
Not a toy. Bitboard position representation, negamax with alpha-beta pruning, a transposition table and centre-first move ordering, searching 9 plies. It will punish a careless move.

How it works: the board is two 49-bit masks, and a four-in-a-row is detected by ANDing the position with itself shifted twice — four shift-pairs cover all 69 possible lines at once. Read the engine.
