SAP BTP engineer who turns business requirements into systems that ship.

SAP Certified Solution Architect for the SAP Business AI Platform and certified in SAP Business Data Cloud. As an SAP BTP consultant at BeCloud I took functional requirements to architecture, CAP/CDS services, Fiori/UI5 apps, automated tests, and release.

01 / Selected work

Evidence over buzzwords.

Much of my best work is under NDA. Each case shows the problem, what I owned, and the decisions I made—with public code wherever it can be inspected.

SAP solution delivery

From refined requirements to a testable SAP delivery.

My contract title was SAP Consultant. In practice, I turned functional requirements into architecture and full-stack delivery: interface and UX, domain model, integration, deployment, test automation, and environment troubleshooting.

12CAP service tests in the public reference, plus a formal QA stage
  • Refined requirements with the functional consultant and proposed architecture, flow, and UX improvements
  • Designed and built across SAP BTP, Fiori, CAP/CDS, Work Zone, HANA, and Joule
  • Introduced automated testing and a QA stage beyond direct dev-to-production fixes

02Architecture decision · In progress

Confidential cloud platform

Changing the foundation when the economics stop making sense.

I evaluated the cost and technical fit of an existing AWS direction, proposed a clean re-platform to Google Cloud, and built enough alignment to restart on a foundation better suited to the product and team.

AWS → GCPRe-platform recommended and defended on cost and fit
  • Compared cloud economics and operational tradeoffs
  • Recommended AWS → Google Cloud and defended the decision
  • Aligned stakeholders around “start again, but start well”
  • AWS → GCP
  • Cost architecture
  • Technical strategy
  • Stakeholder alignment

Clinipets

A veterinary platform designed for real operational constraints.

A B2B2C system connecting clinics, veterinary teams, tutors, and pets. I own the product and architecture end to end—from tenant boundaries and clinical integrity to mobile/web delivery and infrastructure.

B2B2CClinics, vets, tutors and pets on one multi-tenant platform
  • Conflict-safe scheduling and clinic-scoped roles
  • Versioned clinical records, signatures, and auditable addenda
  • Signed idempotent payments, private-file quarantine, and outbox notifications

Grounded Knowledge Assistant

Making AI answers fail closed when the evidence is missing.

A deliberately small TypeScript RAG reference that makes retrieval, source grounding, citation validation, and safe refusal behavior inspectable and testable.

  • 12 unit/adversarial tests plus 4 Chromium E2E checks with Playwright

02 / Experience

Enterprise SAP delivery, backed by full-stack depth.

I create the most value between a functional requirement and a production release: I challenge the first solution, choose a defensible architecture, build it, and lead validation until it ships.

03 / Capabilities

Stacks change. Engineering responsibility does not.

I ramp up by mapping the domain, contracts, data, failure modes, and delivery path first. That model has transferred across Kotlin/Spring, TypeScript/Node, React/Next.js, SAP BTP, cloud, and applied AI.

04 / Working style

“I do not stop at the ticket—I question the architecture, flow, and failure modes.”

Tools change faster than fundamentals. My edge is not one stack: it is understanding the whole system—business process, data, integrations, failure modes—making a clear decision, and learning whatever the delivery requires. The SAP certifications are recent proof of how fast I ramp up.

I am based in Temuco, Chile, and seeking salaried software roles with immediate availability. I am open to remote, hybrid, or on-site work and relocation within Chile. Spanish is native; English is B2 and operational for technical conversations.
