• Develop and support modules across legacy and new card-management applications in core Java, Struts and in-house frameworks.
• Investigate and resolve production issues on live payment systems, often under tight timelines.
• Build multi-threaded batch jobs and tune SQL for high-volume financial data, checking execution plans before and after each change.
• Work within PCI DSS; every change passes code review and SonarQube, PMD, SpotBugs and Checkstyle gates.
• Contributed to the platform migration from Java 8 to a current Java LTS.

• Built backend services in Python (Flask) with PostgreSQL.
• Containerised applications with Docker and deployed them to the cloud.

• Migrated a legacy .NET application to Python (Django) with a redesigned database schema and data migration scripts.
• Set up cloud infrastructure and CI/CD pipelines with GitHub Actions.
• Built frontend features with React and Next.js.

• Built a learning project with Python (Django) and a React frontend.

Code-knowledge system

Autonomous agents read legacy Java services, learn their business logic and publish a versioned knowledge graph. A retrieval server answers questions over MCP, and every fact is cited to code or database evidence.

Multi-Manager

A desktop app that restored server access after off-the-shelf clients stopped working, then gave AI assistants controlled access to servers, Jira, Confluence, Bitbucket and TeamCity through MCP.

Code-analysis engine

Headless IntelliJ services in Kotlin that give AI agents exact facts about Java code: symbols, references, call paths, decision trees and the SQL a method runs.
