I’ve been writing code long enough to have lived through the eras of the web:
- The LAMP age 🔦 — PHP monoliths, hand-coded logic, manuals & books on my desk 📚
- The API awakening 🔌 — REST & OpenAPI 📜, learning to separate concerns
- The rise of GraphQL 🧬 — contracts first, flexible backends, federation
- The front-end revolutions ⚛️🔥 — React, Next.js, Svelte, PWA 📱
- The real-time wave 📡 — WebSockets, SSE, event-driven backends ⚙️
- The AI-driven present 🤖 — LLMs, Agents 🤝, RAG pipelines 🧠📚, multi-agent orchestration
From building e-commerce platforms 🛒 and CRP/ERP systems 🏢 to architecting multi-tenant SaaS ☁️ with event buses 🚌, MCP servers 🧰, and secure PostgreSQL 🐘🛡️, I’ve seen (and shipped) every layer of the stack evolve.
Once I coded everything by hand 🛠️. Then StackOverflow became my daily partner 💡.
Now, LLMs and Agents give me the leverage to bootstrap and deliver complete, production-grade systems faster than ever ⚡🚀🏭.
Currently, I’m CTO & partner at:
- Squirrel — Digital agency, 50+ complex projects delivered 🧩
- Fidelatoo — Merchant loyalty SaaS (60k+ monthly users, 5k+ businesses) 🎯
- Noula — Mobility & community platform 🚐
What I design and operate today:
- APIs (REST, GraphQL, event-sourced) 🧱
- Event systems (NATS, Kafka) 📬
- Streaming (SSE, WebSocket) 🌐
- MCP servers & AI agents (tool-oriented workflows) 🧠🔧
- PostgreSQL with RLS & SQLC 🐘🛡️
- Real-time SaaS architectures ⏱️
My philosophy is simple:
Design with clarity, deliver with speed, scale with resilience. ✨⚡🪨
