Database Engineering That Performs Under Pressure

MusTech Consulting was founded to bring senior-level database engineering to organisations that need it most — without the overhead of a large consultancy. With over 10 years of hands-on DBA experience, I specialise in designing, administering, migrating, and optimising databases across all major platforms: Oracle, PostgreSQL, SQL Server, MySQL, and MongoDB for unstructured data.

My cloud experience spans all four major providers — AWS (RDS, Aurora, Redshift, DynamoDB), Microsoft Azure (Azure SQL, Cosmos DB, Synapse), Google Cloud (BigQuery, Cloud SQL, Spanner), and Oracle OCI (Autonomous DB, Exadata, MySQL HeatWave) — as well as Snowflake, Databricks, and big data platforms.

I design end-to-end data architectures, perform deep performance tuning (AWR reports, execution plans, indexing strategies), set up high-availability and disaster recovery solutions, and execute zero-downtime database migrations across on-premises and cloud environments.

Every engagement is hands-on, automation-first, and built for long-term reliability — including AI and ML integration into modern data architectures where needed.

How we work

Our Approach

Principles that guide every database and cloud engagement.

Reliability First

High availability, automated backups, replication, and failover are not optional extras — they are built into every solution we design from day one.

Security by Default

Encryption at rest and in transit, least-privilege access controls, audit logging, and compliance-aware design are standard — not bolt-ons.

Automation & Ownership

We automate every repeatable task with Terraform, scripts, and pipelines — then document and hand off so your team can operate it confidently without us.

In the Field

Real Work. Real Environments.

From data centre infrastructure to cloud dashboards and client architecture sessions.
