02 / SOFTWARE SUPPORT & TROUBLESHOOTING

Get your existing software working reliably.

Recurring defects and slow workflows take time away from your team. I help investigate problems across C#/.NET, Angular, React, Vue, Blazor, databases, and Azure, then work with your team on a focused fix and a way to verify it.

Part-time remote consulting · Around 10–20 hours/week. Scope and meeting overlap agreed before work begins.

IS THIS A FIT?

When this helps most

  • A recurring bug or integration failure is difficult to reproduce or explain.
  • An application or database query is slow and your team needs help finding the bottleneck.
  • Your team needs a senior developer for a small backlog of maintenance and fixes.

HOW I CAN HELP

What working together looks like

01

Reproduce and investigate

Review symptoms, logs, and relevant code with your team, then narrow down the cause before changing the system.

02

Fix and verify

Implement an agreed fix, add useful regression coverage, and check the affected workflows.

03

Performance investigation

Examine application and database behaviour, identify bottlenecks, and compare results before and after a targeted change.

04

Support your team

Document the diagnosis and changes, and agree on follow-up maintenance. Work is scheduled within part-time hours; this is not a 24/7 on-call service.
