Case Studies

Selected engineering work

Project recovery

Project Recovery & Product Delivery

Context
A product whose development had stalled.
Challenge
Restore technical direction and delivery, and move the product toward beta and production readiness.
Work
Took hands-on responsibility for technical direction, architecture, engineering quality and delivery. Worked on technical debt, the development workflow and team structure.
Data processing

Large-Scale Catalog Synchronization

Context
A catalog with more than 10 million items that had to be processed and synchronized.
Challenge
A full synchronization run took about 9 days.
Work
Reworked the processing and synchronization pipeline.
Result
Execution time reduced from approximately 9 days to 1 hour.
Performance

Performance Optimization

Context
Production PHP applications suffering from slow pages and high server load. Examples from different projects.
Work
Profiling, database query optimization, PHP-FPM tuning and optimization of expensive business logic.
Results
  • PHP-FPM load reduced by 90%.
  • Heavy page response time reduced from ~16 s to 2.5 s.
Business logic

Complex Business Logic & Data Processing

Context
Business systems with complex calculations, integrations, synchronization and data-intensive workflows.
Challenge
Multi-level pricing calculations were too slow for day-to-day operations.
Result
Calculation time reduced from 1 hour to 10 minutes.
Engineering process

Engineering Process & Team Improvement

Context
Teams where delivery suffered from unclear tasks, inconsistent standards and coordination problems.
Work
Improved technical workflows, introduced engineering standards and code review practices, decomposed work into implementable tasks and reorganized team responsibilities.
Dev tools for AI

Multi-Agent AI System

Context
An in-house project exploring role-based AI agents and how they interact to solve tasks together.
Focus
Agent roles, interaction protocols between agents, and integration with AI models.
Status
Alpha Already used in our daily work and refined as real usage shows what is needed.

Approach

How we work

  1. Business problem first

    Understand what the business needs before choosing a technical solution.

  2. Risks early

    Identify risks and constraints at the start, not in the middle of delivery.

  3. Explicit trade-offs

    Architecture decisions and their trade-offs are written down and discussed.

  4. No unnecessary complexity

    Maintainable solutions over clever ones.

  5. Measured results

    Changes are validated through testing and measurable outcomes.

  6. Clear communication

    Honest updates on scope, risks and progress.
