Helsinki, Finland - 1:17 pm local time
Database Engineer with 10+ years of experience specializing in PostgreSQL and SQL Server — migrations, performance tuning, and production DBA work.

I work with companies that need their database environments handled properly: cleanly migrated, well-optimized, and reliably maintained. My background includes managing production PostgreSQL and MSSQL systems in high-availability configurations for a global software company.

What I can help you with
━━━━━━━━━━━━━━━━━━━━━━━
✔ MSSQL → PostgreSQL migrations (schema, data, stored procedures)
✔ PostgreSQL & SQL Server performance tuning and query optimization
✔ Database administration — backup, recovery, monitoring, HA setup
✔ ETL pipelines and data migration automation (Python / SQL)
✔ Backend API development with database-heavy logic (FastAPI / Node.js)
✔ Schema design, indexing strategy, and capacity planning

Production experience
━━━━━━━━━━━━━━━━━━━━
Currently managing live PostgreSQL and MSSQL environments including:
- High-availability configurations and failover management
- Backup and recovery strategies for large-scale databases
- Performance diagnostics and infrastructure monitoring
- Large-scale data migrations across cloud and on-premise systems

How I work
━━━━━━━━━━
I take database work seriously — clean documentation, tested scripts, and no shortcuts on production systems. I use modern tooling where it accelerates delivery without compromising quality.

If you need a reliable database engineer for a migration, optimization project, or ongoing DBA support, feel free to reach out.

    Bash script SQLITE DB migration Mehedi did an outstanding job on my bash script db migration tool. The code was clean and accurate. After he submitted to me the tool, there was a minor error which he correctly immediately. And with a few messages together, problems were resolved. An excellent freelancer. I really appreciate his work. Saved my butt on a larger project. Thanks Mahedi.
