Case Studies

Background

A media analytics company had a PHP application that powered their core reporting platform. The system had grown organically over 8 years and was showing its age.

The Challenge

The application was experiencing frequent timeouts during report generation, deployments were manual and error-prone, and the development team was afraid to make changes due to lack of test coverage.

What I Did

• Conducted a full system audit to identify root causes
• Implemented database query optimizations that reduced report generation time by 70%
• Established a CI/CD pipeline with automated testing
• Introduced progressive refactoring patterns the team could continue

Background

A large-scale e-commerce platform served hundreds of dealer businesses across global markets. The system had grown over several years with multiple technology stacks and was becoming difficult to maintain.

The Challenge

Critical integrations between systems had undocumented behavior. Deployment processes were fragile. The codebase spanned multiple languages and frameworks, making it hard for any single engineer to work across the full system.

What I Did

• Developed and maintained client-facing systems supporting 200+ businesses across global markets
• Documented undocumented integrations through code analysis and testing
• Designed CI pipelines enabling frequent, reliable deployments
• Established patterns for working across the multi-stack codebase

Background

A lean B2B analytics firm had outgrown their initial architecture. What worked for 100 customers was failing at 1,000.

The Challenge

Database queries that were fast with small data sets were now causing timeouts. Background job processing was unreliable. The team was spending more time firefighting than building features.

What I Did

• Identified the top 10 problematic queries and optimized them
• Redesigned the background job architecture for reliability
• Implemented proper monitoring and alerting
• Created runbooks for common operational issues
