Monthly cloud spend, GCP App Engine

$2,000 a month, unchanged since 2016$2,000

Nine years flat, then about 97% lower, with no loss in service quality.

I'm a senior full stack engineer and AI engineer based in the Philippines and the UAE. I've been shipping software since 2021: backends first, then whole products, and now the AI pipelines that sit inside them.

The work I like best is the kind nobody had time for. A cloud bill that hadn't been questioned since 2016. A security assessment passed on the first attempt. A health data model where even matching two records leaves an audit trail.

I started part-time, about two hours a day, while finishing a Computer Engineering degree. At MySigrid I was given senior-level ownership within my first year, and I now lead the company's AI work: custom agents, RAG pipelines and workflow automation.

MySigrid · Security

Passing CASA Tier 2 on the first attempt

The MySigrid console cleared TAC Security's CASA Tier 2 assessment without a second round. That secured Google App Verification and kept access to sensitive Google API scopes.

Client · Healthcare data

Health data as a property of linkage

A two-service clinical research CRM for a psychedelic-therapy lab. De-identified trial records and identifiable intake records stay apart, and matching them is itself a permissioned, audited operation.

Client · Spec audit

Auditing a CRM against its spec

About 60 checkpoints, from enum vocabularies to SLA clock arithmetic. The prioritised report surfaced an unauthenticated endpoint exposing internal SLA targets and staff names.
