Find What Is Wrong. Fix What Matters. Move On.
When your application has performance problems, security concerns, or mysterious production issues, we provide systematic diagnosis backed by senior engineering experience and AI-assisted analysis. Targeted fixes for what is critical. A clear plan for everything else.
Sound familiar?
When Something Is Wrong and Nobody Knows Why
Your application is slow and you do not know why.
Page loads take seconds instead of milliseconds. API responses are timing out. Your team has spent weeks investigating without finding the root cause. You need someone who has debugged these problems hundreds of times before.
A security audit flagged issues you do not understand.
You received a penetration test report full of critical findings. Your team cannot assess which findings are genuinely dangerous in your context. You need someone to translate audit findings into a prioritised action plan.
Something keeps breaking in production and nobody can figure out why.
The same error keeps appearing. Your team has applied fixes that seemed to work, but the problem returns. You are chasing symptoms instead of causes and need systematic root cause analysis.
The Source Stream difference
Systematic Diagnosis, Not Guesswork
Systematic diagnosis backed by experience
We follow a structured diagnostic methodology refined across hundreds of production systems. Senior engineers who have seen these patterns can often identify the likely cause within hours. A memory leak, a connection pool misconfiguration, an N+1 query pattern -- experience is the difference between days of investigation and weeks.
AI-assisted analysis for faster root cause identification
We use AI-assisted tools to analyse logs at scale, trace request flows through distributed systems, and scan code for vulnerability patterns. The combination of AI coverage and human judgement is faster and more thorough than either approach alone.
Clear explanations, not just fixes
We explain what went wrong, why, and what your team can do to prevent it happening again. Every engagement produces a written report your team can learn from and reference in the future.
Deliverables
What You Get
Root cause analysis report
Detailed, evidence-based identification of the underlying cause with supporting data and a clear chain of reasoning.
Performance profiling results
Comprehensive analysis showing where time is being spent, which components are the bottleneck, and the quantified impact on user experience.
Security assessment
Evaluation of vulnerabilities with severity ratings, exploitation likelihood in your context, and prioritised remediation recommendations.
Fix implementation for critical issues
Direct remediation of the most impactful problems, tested and verified before deployment.
Architecture review
Assessment of whether the underlying architecture is contributing to the problems and whether structural changes are needed.
Remediation roadmap
Prioritised plan for addressing remaining issues after critical fixes, with effort estimates and recommended sequencing.
Test coverage improvements
Additional automated tests targeting the specific failure modes identified during diagnosis.
Our process
How It Works
Initial Diagnosis
Day 1-3We gain access to your systems, deploy profiling tools, and conduct initial analysis. In most cases, we identify the likely root cause within the first three days.
Deep Analysis
Week 1Thorough investigation: targeted code review, performance profiling, log analysis at scale, and load testing. We document the root cause with evidence.
Fix & Verify
Week 1-3We implement fixes for critical issues, validate in staging, deploy with enhanced monitoring, and confirm resolution with before-and-after measurements.
Report & Recommendations
Week 3-4We deliver the complete report: what was wrong, what caused it, what we fixed, what remains, and what your team should do to prevent recurrence.
