Embedded realtime database with vector search (HNSW), BM25, RRF hybrid retrieval, Boolean DSL, real-time SUB/UNSUB push, and ACID transactions with WAL. One self-contained binary under 1 MB. Apache-2.0.

Banking transaction simulator demonstrating race conditions and concurrency control strategies (optimistic/pessimistic locking)

A production-ready FastAPI-based wallet service integrating Paystack for payment processing and Google OAuth for authentication. The system supports dual authentication modes: JWT tokens for end-users and API keys for service-to-service communication, Include wallet deposits via Paystack with secure webhook verification, wallet-to-wallet transfers

PostgreSQL bank-transfer ledger demonstrating ACID guarantees — atomic transfers via BEGIN/COMMIT/ROLLBACK, constraint-based consistency, and concurrency-isolation testing with Python & SQLAlchemy. (WIP)

A tool to construct Pourbaix diagrams from first principles calculations without knowledge of redox or acid-base equilibria

A real relational database engine from scratch in pure Python, zero dependencies: checksummed paged storage, a bounded buffer pool, a B+Tree with secondary indexes and overflow pages, a WAL with crash recovery, MVCC transactions, a SQL parser + planner (joins, aggregation), a DB-API 2.0 driver, and a client/server.

FSM-based transaction engine with exactly-once state guarantees using outbox pattern and optimistic locking

Database performance engineering lab demonstrating 148x query optimization through advanced indexing strategies and ACID-compliant transaction patterns. Features production-ready implementations spanning both SQL and NoSQL paradigms with measured performance analytics. A practical showcase of database engineering principles.
