I'm Potito Coluccelli, a software architect and team lead based in Milan, Italy. I have been building enterprise software since 2007, mostly on Java and Spring, for high-criticality sectors such as energy trading, banking, telco and insurance.
I design and scale distributed systems, microservices and cloud-native solutions, and I lead the team that builds them. I hold the Claude Certified Architect – Foundations certification from Anthropic and I work on bringing AI into enterprise Java products. I'm also the author of the Manning liveProject series “REST Services with Spring and JPA”.
Design and development of backend systems with Java, Spring Boot and Spring Batch: REST APIs, microservices, messaging, batch processing and integrations with third-party platforms, on PostgreSQL and Oracle, deployed with Docker on AWS. Earlier in my career I was a JBoss middleware consultant at Red Hat, working on migrations, performance tuning and training for major Italian banks and insurance companies.
As a Claude Certified Architect I design LLM-based applications with the Claude API, the Claude Agent SDK and the Model Context Protocol (MCP): tool use, agentic loops, multi-agent orchestration and context management. I work on evolving enterprise software products with AI-powered features and integration with AI assistants, and on agentic software development, where coding agents such as Claude Code become part of the team's engineering workflow.
I lead a product team in a customer-facing role: technical point of reference for customers, milestone negotiation with customers and partners, and Scrum Master experience with a multicultural team on an Azure-based solution. I care about turning complex business requirements into robust, maintainable software.
I lead the team behind BizPro, a tool that automatically detects suspicious transactions and orders for REMIT/MAR compliance in energy trading. Spring Boot backend with REST APIs, Angular/TypeScript console, Spring Batch processing and Java/C# connectors to the main trading systems (Trayport, ICE, EPEX).
Author of the liveProject series “REST Services with Spring and JPA”.
Designed and developed the first version of BizPro and solutions based on onStage, Bizmatica's API management platform, with microservices architectures (Spring Boot, AWS, Docker, Hazelcast, Redis).
Real-time, rule-based campaign and offer management software for telco operators (Java, Spring, MySQL, Python).
JBoss consultant and trainer: application migrations, health checks, JVM and performance tuning for banks, insurance companies and public administration, in Italy and abroad.
B2B portals and contract management for Terna, the Italian electricity transmission system operator, and Alfresco-based document management systems.
I'm the author of the Manning liveProject series:
REST Services with Spring and JPA
A hands-on series of projects: create and configure containerized Spring Boot applications that interact with PostgreSQL, design and implement REST services and secure them with Spring Security.
