A full stack engineer with eight years in fintech and energy - domains where correctness isn't optional. I now work independently: taking products from first commit to live, and making existing systems hold up under real use.
Database, backend, UI and deploy - owned end to end, working solo or embedded in your team. For when the thing needs building and there are no engineers spare to build it.
For systems that work until they don't - data going missing, jobs failing quietly, load breaking things at the worst moment. I find the cause, fix it, and leave you able to see the next one coming.
Payment providers, identity, third-party data - integrations are never as simple as the docs suggest. I've worked both sides: consuming them, and building the API platform other businesses integrated with.
Architecture decisions, code review and mentoring, from someone who has managed engineers as well as shipped code. When the work outgrows one person, I can bring in engineers I've worked with and trust.
