Software Architect, tech lead

Esperienze

I am currently employed at The Nielsen Company as SW Architect and Tech Lead based in Milan, Italy, working with remote international scrum teams.
In the past 15 years, I’ve been working with Java EE, focused on developing web applications, then moved to API design and progressive web apps using microservice patterns and different backend technologies such as Java/Spring Boot, Python, NodeJS, all running as Docker containers into Kubernetes clusters. 
My actual role is SW architect and Tech team lead. 
I managed various developer teams, including international teams working on full Web stacks. 
I have created the architecture of the API layer for several services developed by the company, with REST API and GraphQL API.
I am strongly focused on AWS cloud architecture and CI/CD delivery cycle with Jenkins/Bitbucket and Gitlab.
I also have such long experience in database and SQL design on many RDBMS such as Oracle, PostgreSQL, MS SQL and NoSQL like MongoDB, DynamoDB.
My experience includes all the activities related to software development and delivery: analyzing business requirements, converting them to system requirements, providing solutions using technical documentation, designing the architecture, assigning tasks to resources and applying agile methodologies such as Scrum Safe and LeSS.
I consider myself proactive and open, lover of technology in general and interested both in personal and professional growth.
