Building an offline password manager and making the security, storage, and product calls around it. It uses the same habits as database work: assume failure, keep control of the data, and avoid magic.

A short enterprise database project focused on keeping the setup operable under real constraints.

Independent technical work across SEO, websites, and content systems. This is where product, search, and commercial decisions became part of the same work as the engineering.

Database engineering in a banking environment, with the usual need for careful changes and boring reliability.

Database work for logistics systems, where slow systems and failed jobs quickly become real business problems.

A longer database engineering period across enterprise operations, incidents, change work, and support.

Oracle-heavy database work covering operations, performance, and the details that decide whether a system behaves in production.

Database administration in banking. Small changes still needed the care of production work.

UK-based database administration that helped me work across different delivery habits, tools, and client expectations.

Infrastructure and database support in a larger enterprise setting, with tickets, incidents, process, and careful changes.

Enterprise operations and support work where the handover mattered as much as the fix.

Early database administration work in a larger delivery environment. Documentation, escalation, and repeatable fixes were already part of the job.
