Iβve been writing code long enough to have lived through the eras of the web:
- The LAMP age π¦ β PHP monoliths, hand-coded logic, manuals & books on my desk π
- The API awakening π β REST & OpenAPI π, learning to separate concerns
- The rise of GraphQL 𧬠β contracts first, flexible backends, federation
- The front-end revolutions βοΈπ₯ β React, Next.js, Svelte, PWA π±
- The real-time wave π‘ β WebSockets, SSE, event-driven backends βοΈ
- The AI-driven present π€ β LLMs, Agents π€, RAG pipelines π§ π, multi-agent orchestration
From building e-commerce platforms π and CRP/ERP systems π’ to architecting multi-tenant SaaS βοΈ with event buses π, MCP servers π§°, and secure PostgreSQL ππ‘οΈ, Iβve seen (and shipped) every layer of the stack evolve.
Once I coded everything by hand π οΈ. Then StackOverflow became my daily partner π‘.
Now, LLMs and Agents give me the leverage to bootstrap and deliver complete, production-grade systems faster than ever β‘ππ.
Currently, Iβm CTO & partner at:
- Squirrel β Digital agency, 50+ complex projects delivered π§©
- Fidelatoo β Merchant loyalty SaaS (60k+ monthly users, 5k+ businesses) π―
- Noula β Mobility & community platform π
What I design and operate today:
- APIs (REST, GraphQL, event-sourced) π§±
- Event systems (NATS, Kafka) π¬
- Streaming (SSE, WebSocket) π
- MCP servers & AI agents (tool-oriented workflows) π§ π§
- PostgreSQL with RLS & SQLC ππ‘οΈ
- Real-time SaaS architectures β±οΈ
My philosophy is simple:
Design with clarity, deliver with speed, scale with resilience. β¨β‘πͺ¨
