About this gig

Hello, I specialize in analyzing, identifying, and cross-verifying software defects to accelerate fix-cycles and stabilize release branches.

If your database is dragging or causing timeouts, I will translate complex requirements into optimized database schemas (PostgreSQL, MSSQL, MySQL, Oracle, MongoDB, Redis) to dramatically reduce response latencies on heavy backend queries.


Expert Solutions Provided:

- High-priority bug fixing in React, Next.js, and Node.js/Express

- Slow SQL/NoSQL query and database schema optimization

- Data modeling, flow designs, and schema mapping

- Deep troubleshooting for authentication or integration failures
