Keep your databases fast, reliable, secure, and cost-effective — on real Linux infrastructure.
Deep systems-level expertise in both Linux and PostgreSQL is rare. Most teams have application developers who know some SQL, or cloud DBAs who only work with managed services. We own the full stack: the operating system and the database. That combination lets us solve performance, reliability, and cost problems that others cannot.

What We Deliver

• Performance audits & tuning •
Query plans, vacuum strategy, indexing, connection pooling, and Linux kernel/sysctl tuning that deliver measurable speed and stability gains.

• High-availability & resilience •
Streaming and logical replication, clustering, automatic failover, and tested disaster-recovery setups.

• Migrations & modernization •
Oracle, MySQL, or SQL Server → PostgreSQL. Self-managed managed. Multi-tenant redesigns. Unit-tested and automated where possible, with minimal downtime.

• Security hardening •
Linux + PostgreSQL security baselines for production environments, including access controls, encryption, auditing, and compliance-ready configurations.

• Fractional DBA + Sysadmin coverage •
Ongoing retainer or on-call support for teams that need senior expertise without a full-time hire.

We work on fixed-scope projects or ongoing fractional engagements. You get clear deliverables, knowledge transfer, and no black boxes.

Managed PostgreSQL Service (DBA-as-a-Service)

• Remote monitoring, backups, tuning, upgrades, and coverage for companies running their own PostgreSQL on Linux. Ideal when you want control and lower cost than fully managed cloud databases, without carrying the operational burden yourself.

• Guarantee on instance location to meet data sovereignty governance laws.

Training & Knowledge Transfer

We train your engineering teams to do what we do. No trade secrets — the goal is to make your internal team stronger and less dependent on external help over time.

Specialized Expertise

• PostgreSQL for AI / RAG / Agents •
Companies are putting vectors and agent memory into PostgreSQL and then hitting performance and operational limits. We help you run these workloads reliably at scale.

• Multi-tenant SaaS backends •
Tenant isolation, noisy-neighbour problems, cost control, and safe schema design patterns.

• Migrations off proprietary databases •
Move from expensive Oracle/SQL Server licences or clunky MySQL/Firebird/SQLite instances onto PostgreSQL on Linux — with testing, automation, and a clear cut-over plan.

• Self-managed & hybrid cloud •
For teams that deliberately avoid full lock-in to managed services and still need production-grade expertise.

• Caching •
What to cache — When to cache. We provide a combined solution where PostgreSQL and a cache in the form of integrated architecture.
