Deep expertise in Core/Vanilla PHP with a strong grasp of OOP, SOLID principles, design patterns, REST APIs, and service/microservice architecture, going all the way to the coding container initialization. I strive to write clean, maintainable, and well-documented code aligned with modern standards. Over the years, I’ve complemented these fundamentals with extensive framework experience, working with Laravel, Symfony, and custom-built solutions based on microframeworks like Slim, to deliver scalable, testable, and reliable systems.
Over the past 5 years, I mainly worked on migrations from legacy systems to new, freshly built systems. The goal was to build an extendable and maintainable platform with event‑driven messaging. After defining the base architecture, we closed gaps by replicating features from the old system, so all customers could move without data or feature loss. This also included non‑engineering work such as writing epics, spotting blockers in my team and in other teams that rely on the core system, organizing technical discussions before implementation, and distributing work to support agile delivery instead of urgent, error‑driven reactions.
I have experience with applications handling around 2M unique requests per day. In these cases, I use caching for different data types, optimize and batch external API calls to other services, and improve performance through code optimization and regular refactoring cycles.
I have more than 50 different integrations so far in my career with various 3rd party services, from payment gateways, to gaming providers, to SMS services, to exchange rate providers, to email campaign providers, to national corporate registries to automate company verification and onboarding, etc.
I have worked with both PHP execution models, PHP‑FPM and event‑loop runtimes. I understand the pros and cons of each and when to use them. This helps me make clear tech stack decisions for new projects based on the workload and performance needs.
For years, I have written unit and functional tests for my code. I regularly participate in code reviews to ensure best practices and keep coverage high. Testing code that instantiates the application container requires extra time and effort, but aiming for 100% coverage gives everyone confidence and reduces regressions.
