What I Can Do For You

How I Can Help You

Engineering approach to concrete operational problems. No unnecessary buzzwords, only measurable solutions that eliminate bottlenecks.

01 // OPS

Automation & Delivery

Resilient CI/CD pipelines, automated testing suites, containerization, and self-updating systems with zero downtime.

Continuous Integration & Deployment pipelines (GitHub Actions, GitLab CI, Docker)
Dramatic lead-time reduction and elimination of production regressions
Live telemetry, health metrics, and automated rollback upon anomaly
Real-world proof:

"Daily production experience with mission-critical air navigation systems (IDSAirnav / ENAV Group)."

Explore case study
02 // DEV

Full-Stack Development

Complete, performant, and maintainable web applications: from database schema design to responsive UI.

Robust Python backends (Flask, Django, FastAPI) and Node.js with PostgreSQL / PostGIS
Modern, reactive frontends in Angular and React with declarative state management
Third-party API integrations (Stripe checkout, WhatsApp Cloud API, ReportLab vector PDFs)
Real-world proof:

"Central Parking (live in production processing thousands of vouchers/mo) and Harbor Manager."

03 // AI

Applied AI & Research

Not AI hype, but precision problem-solving: constrained mathematical optimization, matching algorithms, NLP, and model defense.

Mathematical constrained optimization (Google OR-Tools, CP-SAT, 2D packing)
Asynchronous agentic architectures with real-time token streaming (Celery, Redis, SSE, Gemini)
Defense and adversarial robustness for NLP/LLM models (Master's Thesis BERT4Def)
Real-world proof:

"Harbor Manager (OR-Tools CP-SAT), NutriFit (Celery/Redis/Gemini SSE), NLP Research Univ. Pisa & BERT4Def Thesis."
