Does This Sound Familiar?

These are the problems I solve every day. For over 20 years.

❌ Production Crisis

System crashed, team can't find the cause, every minute costs money

❌ Legacy System

System is 10-15 years old, nobody understands how it works, everyone's afraid to touch it

❌ Slow SQL Server

Performance degrading, queries slow, don't know what to optimize

❌ Contractor Can't Solve It

External company can't handle the problem, need expert escalation

❌ Migrate or Upgrade?

Don't know whether to rewrite the system or continue maintaining it

❌ No Documentation

Original developer left, no documentation, new team doesn't understand the code

❌ Security Issues

Security audit found vulnerabilities, need to fix fast without breaking anything

❌ Scalability Stuck

System can't handle load, need to scale but architecture doesn't allow it

❌ Integration Failures

External API behaving strangely, unclear where the problem is - our side or theirs
