Key Projects (The "Proof" Section)
Legacy Modernization Project (Phalcon to Laravel)
Challenge: Client was stuck on an unmaintainable legacy framework with high vendor-lock-in risk.
Solution: Built a bridge layer to allow parallel execution of both frameworks. Migrated high-risk modules first while keeping the legacy system operational.
Result: Reduced Total Cost of Ownership (TCO) and enabled the client to ship new features 30% faster.
Automation & AI-Driven Workflow
Challenge: Manual data entry and filtering were creating bottlenecks in client operations.
Solution: Integrated LLM agents into existing workflows for intelligent automation of sales.
Result: Automated 16h of manual labor per week.
