I build backend systems and developer tools around SQL and data-heavy workflows. My recent work includes static SQL analysis, PostgreSQL schema tooling, an Oracle transaction system and a controlled text-to-SQL pipeline.

Featured project

SQL Atlas

Deterministic SQL analysis across the terminal, pull requests, VS Code and the browser. One shared TypeScript core powers the published npm CLI, GitHub Action annotations, editor diagnostics and the interactive web application.

• Rule configuration, repository policies and inline ignores
• PostgreSQL-aware scanning plus EXPLAIN JSON and schema tooling
• Text, JSON, Markdown and SARIF output
• Tested CLI, GitHub Action and VS Code integration

Selected systems

Ask Database A schema-aware text-to-SQL system built around PostgreSQL, Fastify and controlled model output. The backend retrieves relevant schema context, ranks relationship paths and validates generated SQL in Safe Mode. Static demo	VisualDB Studio A local PostgreSQL schema designer with React Flow relationship editing, deterministic validation, schema scoring and DDL generation. Live app
OraBank An Oracle SQL and PL/SQL reference system covering transaction consistency, deterministic row locking, savepoints, auditing, Scheduler jobs, privileges and recovery runbooks. Technical walkthrough	Engineering focus Backend application design, relational data modelling, SQL analysis, automation and tools that keep system behaviour visible and testable. View portfolio

Open source

• Truta446/nplusone #29 - added an MSSQL adapter with query, parameter and stored procedure coverage
• Truta446/nplusone #13 - added tested LibSQL and Turso adapter support

Both changes were merged into the upstream project. I focus external contributions on reproducible behaviour, implementation and regression tests.
