SYSTEM // backend · cloud · ai-integration

I design backend systems that pay people, move freight, and stay up. Currently leading delivery for Big4 engagements at SyanSoft Technologies — Java, Spring Boot, microservices, and the operational discipline to keep them all running.

// Five rules I bring to every system I design:
$ design --failure-mode-first // the success path will sort itself
$ prefer boring-tech // Postgres > novelty, every time
$ make --ops-the-feature // telemetry, runbooks, dashboards from day 1
$ version contracts --strict // breaking changes ship as v2, never as a surprise
$ document decisions // ADRs in /docs · every "why" outlives me

04 / Contact

Let's design the
failure mode first.

If you're building something that needs to stay up — payments, logistics, AI on top of real data, or an architecture that's stopped scaling — I'd like to hear about it.
