About Me
Solution-oriented software engineer focused on high-complexity systems: microservice architecture, distributed systems and real-time communication. I work across Backend and Mobile, connecting scalable infrastructure to efficient, responsive user experiences.
Professional Summary
Software development professional specialized in designing, refactoring and optimizing end-to-end digital platforms. Extensive experience building high-concurrency APIs, event-driven microservices (WebSockets / gRPC) and ecosystems for urban mobility and omnichannel messaging. I bridge distinct ecosystems: native modules, hybrid frameworks and bidirectional connectivity across languages.
Technical Stack
- Languages & Backend: PHP (Laravel), JavaScript/TypeScript (Node.js), Go, Python, Java.
- Mobile & Frontend: Flutter, PWAs, bidirectional bridges (native and JS/WebSocket between Flutter and Laravel).
- Real-time & Microservices: WebSockets, gRPC, messaging systems, events and real-time data.
- DevOps & Infrastructure: Docker, Docker Compose, Kubernetes, K3s, CI pipelines and container orchestration.
- Tools & Workflow: terminal-centric workflow (Zsh, tmux), CLI automation and AI-agent-assisted development.
Selected Work
- Mobility & Logistics Platforms (end-to-end): architecture of complete ride-hailing and delivery ecosystems, with background location tracking on mobile, dispatch APIs and distributed communication between backend and clients.
- Omnichannel Messaging: real-time, multilingual chat and support platforms built with WebSockets and Laravel, focused on high concurrency and efficient data persistence.
- Connectivity & Utility Libraries: custom communication libraries that connect mobile apps (Flutter/PWA) to real-time backends, simplifying state and event synchronization.
How I Work
- Clean architecture & refactoring: constant focus on decoupling, maintainability and service-oriented design.
- Systems view: able to move from hardware/telemetry and containers up to mobile screen design.
- Automation & speed: modern engineering flows with AI agents for code acceleration, regression auditing and quality assurance.
