Helsinki, Finland - 5:54 am 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.
