Expert on demand

I consider providing professional services to small and medium business owners on short notice as my mission.

I believe you should not make financial decisions every time you need my support. Hence I offer fixed fees so you know your investment in advance.

We will work directly together without any intermediate parties. This gives you unlimited 24/7 access to me, shorter feedback loops, and lower cost.

My approach encourages flexibly choosing from service options during your path to success, matching your current level of urgency, risk tolerance, and budget.

Site assessment

Do you prepare for strategic investments, and need an independent overview of the current status?

I can guide you through understanding the following key areas:

Such an assessment typically takes 2-4 weeks, and pricing starts at €8900.

PostgreSQL assessment

I solve reliability, performance, and cost challenges related to PostgreSQL, typically dealing with terabyte-scale deployments.

My evidence-based comprehensive approach identifies bottlenecks to create an actionable improvement plan. On top of that, I work together with your team during the process to roll out changes, and tune configuration settings.

It enables continuously acting on new information, benefiting early and gradually from improvements, while also sharing how to keep the database tidy.

This solution includes the following key areas:

  1. Check data safety and business continuity settings and processes
  2. Identify usage patterns, slow queries, and their bottlenecks
  3. Check cache hit ratio for indexes and tables
  4. Fit high-level CPU, RAM, storage, and network settings to the given use case
  5. Remove unused indexes, add missing indexes, and optimize remaining indexes
  6. Check logs for both expected and unusual patterns
  7. Review locks and timeout settings
  8. Identify table and index bloat
  9. Tidy up with VACUUM/ANALYZE/pg_squeeze as needed
  10. Ensure autovacuum settings can keep the database tidy

Such an assessment typically takes 2-4 weeks, and pricing starts at €8900.

CI/CD assessment

Continuous delivery improves software delivery processes across the board: faster cadence, higher quality, and better teamwork. No wonder most organizations wish to adopt this approach.

As both contributor to and signatory of Minimum Viable CD, I find it important to establishing a core set of practices and capabilities required to start gaining the expected benefits while avoiding common pitfalls and mistakes.

Experience shows high performing teams do not have CI/CD – they do CI/CD.

I can assess your software delivery approach to improvement opportunities on your way towards adopting continuous delivery.

Such an assessment typically takes 2-4 weeks, and pricing starts at €8900.
