I’m Ebenézer Marquezine — an engineer by education and a backend developer by passion.
My career journey started in Mechanical Engineering, but I discovered my real fascination lies in building complex, scalable systems and designing clean, maintainable architectures.
💼 Currently: ServiceNow Developer, delivering enterprise-grade solutions.
🛠 Specialties: Backend development, API design, microservices, software architecture, and systems integration.
🚀 Highlight: Architected a microservices-based full-stack app (ft_transcendence) featuring REST APIs, WebSockets, load balancing, caching layers, and presence servers — all following modern industry patterns.
📚 Always learning: From distributed systems to DevOps and cloud-native patterns.
ft_transcendence is my current playground for designing and implementing a real-time, distributed multiplayer platform from the ground up.
It’s where I experiment with high-performance networking, microservices architecture, and industry-grade deployment patterns.
Create a platform where multiple players can interact in real time, with:
- Ultra-low latency
- Fault tolerance
- Easily extendable architecture
- Seamless scaling for thousands of concurrent users
| 🚀 Core | 📡 Communication | ⚖️ Scaling | ⚡ Performance | 🛰 Presence | 📦 Deployment |
|---|---|---|---|---|---|
| Backend-first microservices | REST APIs + WebSockets | Load balancing via reverse proxy | In-memory caching | Dedicated presence server | Dockerized, orchestrated |
- 🔄 Horizontal scaling stress tests for high concurrency.
- 🛡 API gateway and service discovery implementation.
- ⚙ Advanced caching and data sharding.
