As a hands-on Tech Lead in an Agile squad, I owned architecture and code quality, coached developers, and contributed to delivery. I led solution design and development across the team’s application estate per Estreem/Partecis standards, participated in all ceremonies, collaborated closely with BAs and QA, and supported run activities (performance tuning, incident response, L3 support). I provided transparent progress metrics and early escalation on schedule and quality risks.

Translate business specs into technical designs; implement with Java/Spring; lead reviews, testing strategy, and CI/CD quality gates.

Mentor engineers via pairing, design/code reviews; uplift engineering standards and autonomy.

Operate with an SRE mindset: observability, root-cause analysis, and continuous improvement.
