DBM — a SQL Server engineering studio.

DBM (legally Duomenų bazių magija, MB) is a database engineering studio focused on one thing: Microsoft SQL Server. It helps teams make SQL Server fast, move between versions and servers without surprises, and ship schema changes the way they ship application code — with measurable before-and-after numbers, not opinions.

Today, DBM is a one-person studio. Every engagement is handled directly by its founder, Dmitrij Kultasev — there is no account-manager layer, no junior handoff, and no “we’ll loop in a specialist.” You talk to the engineer who does the work, start to finish. The plan is to grow DBM deliberately; for now, staying small is the feature: bank-grade rigor with the directness of working with one senior pair of hands.

What DBM does

• Performance tuning. Query plans, indexes, wait stats, in-memory tables, stored-procedure rewrites — diagnosed and fixed with measurable before/after numbers.
• Migrations & upgrades. Moving between SQL Server versions, server consolidations, and schema re-organisations — with rehearsed rollback plans.
• Database development & CI/CD. SSDT projects in source control, tSQLt unit tests, and automated deploy pipelines with GitHub Actions, Bamboo, or Bitbucket.

What DBM won't pretend to do

• Engines other than SQL Server — no MySQL, PostgreSQL, or NoSQL work.
• Front-end or application-tier work outside the database.
• Open-ended “data strategy” engagements with no measurable outcome.
• Ten things at once. One thing done well beats five projects done half-time.

How engagements usually go

1. Free 30-min consult. You describe the symptoms. DBM tells you whether it can help and roughly what it would take.
2. Scoped phase. A small, time-boxed first phase with a clear deliverable, so you can judge fit before committing further.
3. Ongoing if useful. Many clients then keep DBM engaged on a regular basis. Some don't need it again, and that's a good outcome too.

The person behind DBM

DBM is run by Dmitrij Kultasev, a database engineer who has worked with SQL Server since 2008 — across banking, leasing, fintech, and delivery. The throughline of every role is the same: treat the database as source-controlled, tested, automatically-deployed software rather than a pile of ad-hoc scripts.

On the open-source side he's a contributor to the tSQLt SQL Server unit-testing framework and the author of a Visual Studio Code extension with 32k+ downloads. He works in English, Lithuanian, and Russian, and is based in Lithuania — DBM works remotely with teams worldwide.
