Migrate without downtime
Incremental upgrades, backward-compatible contracts and a rollback at every step. Users should never learn that a migration happened.

01
I work across the whole request, not just one end of it.
I'm a Software Development Engineer at Finzly, where I build and maintain the Angular front ends and Spring Boot services behind a financial platform. My day tends to span both: a WebSocket stream on the server, the chart that renders it, and the query underneath that makes it fast enough to matter.
The work I'm proudest of is unglamorous. I led an Angular migration across three large applications from v6 to v18 with zero downtime — six major versions of breaking changes, with real customers on the other side the whole time. I also built an internal tool that took configuration management across environments away from spreadsheets and Slack threads, which earned a Top Performer award.
Outside of feature work I go looking for the slow parts: refactoring legacy Java, tuning queries, and trimming payloads. Most recently that came to 15% faster API responses and 20% less server load on the services I own.

Measure, then optimise
Profiles and query plans decide what gets tuned. A 15% latency win beats a rewrite nobody asked for.
Build the boring internal tool
The highest-leverage work is often the thing your own team does by hand ten times a week.
Write for the next reader
Explicit naming, thin controllers, typed boundaries. Code someone else can change safely at 2am.
