PROFILE
────────────────────────────────────────────────────────────────────────────────
Full-stack engineer with six years at Capgemini building backend and web systems
for banks, insurers and corporate clients. Currently delivers features end to
end on a retail bank's mobile platform: Java 17 / Spring Boot 3 microservices,
an OpenAPI-first BFF layer on JDK 21 and the React Native app. At home with the
unglamorous side of banking integration (legacy hosts, BPM processes,
multi-environment release pipelines) and with the tooling that keeps a large
multi-repository programme moving. Started out migrating COBOL to Spring Boot;
now spends personal time on LLM-assisted modernisation tooling where the output
is verified, not trusted.

EXPERIENCE
────────────────────────────────────────────────────────────────────────────────

Consultant – Full Stack · Capgemini, Turin, Italy              08/2023 – present
  Mobile banking platform — major Italian retail banking group
                                                               02/2025 – present
• Deliver features end to end across all three layers: Java 17 / Spring Boot 3
  microservices, an OpenAPI-first BFF on JDK 21 and the React Native / Redux
  Toolkit app.
• Design and build new banking product flows and REST APIs, from the OpenAPI
  contract through the BFF and microservice to the app state, including
  hand-offs to the bank's BPM processes.
• Integrate legacy banking systems over SOAP and REST — payments, cards, limits
  and document processing — with the error handling that keeps the app usable
  when a host misbehaves.
• Caching, resilience and observability in production (Hazelcast, Resilience4j,
  Micrometer/Prometheus, Splunk, Dynatrace); Kubernetes deployments through
  Azure DevOps release pipelines across multiple environments.
• Built the team's internal tooling: environment and API-collection generators,
  git guard hooks, end-to-end test harnesses, an LLM-assisted agent workflow
  with a regression suite, and the engineering handbook.
• Mentor junior developers and run knowledge-transfer sessions on Spring Boot
  and React practice.
  Digital HR platform — corporate group                        08/2023 – 02/2025
• Built the employee-facing web platform in React + TypeScript on SharePoint
  Framework, from Figma prototypes to production; REST integration with the HR
  back end; Azure DevOps CI/CD set up together with the DevOps team.

Analyst Consultant – Full Stack · Capgemini, Turin, Italy      01/2021 – 08/2023
Media, insurance and oil & gas clients
• Advertising segmentation tool for a German pay-TV broadcaster: React front end
  for audience targeting, Akka-based microservices and Elasticsearch for
  real-time segmentation; Mocha/Chai tests, releases through UAT to production.
• Oil & gas client: Spring Boot services on Hibernate/PostgreSQL feeding
  Angular.js dashboards; tuned the data pipeline behind them.

Intern – Full Stack · Capgemini, Turin, Italy                  10/2020 – 01/2021
Insurance client
• Migrated a legacy COBOL policy-listing system to Java Spring Boot services
  (Hibernate/JDBC on PostgreSQL) consumed by an Angular.js front end; kept the
  Maven/Git CI running for the team.

Intern – Full Stack · TogoMetrics, Turin, Italy                06/2020 – 09/2020
• React + TypeScript / Node.js MVP for an agri-tech client, built end to end in
  a team of four.

PROJECTS
────────────────────────────────────────────────────────────────────────────────
• LLM-assisted legacy modernisation — COBOL to Spring Boot with
  differential-execution verification of the generated code: the referee that
  proves equivalence is built before the agent that writes the code. Personal
  project. (in progress)
• Engineering-workflow automation — For the banking programme above: LLM agents
  and skills wired to git hooks, an approval gate and a regression suite, so the
  assistant follows the team's branch and review rules instead of bypassing
  them.
