What I'm doing now
A snapshot of my current focus. Last updated 2026-05-05.
At work
Candidate Researcher at TÜBİTAK BİLGEM since August 2025. Day to day, that means backend services in Java and Spring Boot on PostgreSQL, with Hazelcast for distributed caching and Fluent Bit for log shipping.
School
Final-year (4th-year) Computer Engineering at Marmara University. Graduating June 2026. Currently wrapping up the senior engineering project, the FIVUCSAS biometric platform, and preparing a security review for it.
Side projects
- FIVUCSAS: pushing toward a third-party security review. Fernet-encrypted embeddings, WebAuthn passkeys, and row-level-security multi-tenancy.
- Sarnıç: multi-tenant school scheduler with a Timefold solver, replacing a 24-sheet macro Excel for an exam-prep school in İstanbul.
- Mizan: hybrid Quranic search engine (PostgreSQL full-text plus pgvector), with letter and Abjad counts verified against the Tanzil corpus.
- Share Agent: Sharia-compliance-aware BIST trading platform with hexagonal architecture, running on a Hetzner CX43 server behind Traefik.
Reading and learning
- HackerRank: sharpening problem-solving and algorithm skills daily.
- "Clean Code" by Robert C. Martin: read, with the principles applied as a default.
- Hazelcast partitioning and near-cache patterns.
- WebAuthn / FIDO2 ceremony specs (the user-verification flag transitions).
