▋ Full Stack Software Engineer

I'm a Salvadoran software engineer drawn to problems with real stakes — where uptime, data integrity and a clean experience all have to hold at once. By day I build Java & Spring services on GCP at Telus International, currently on their recommendation engine. On the side I design AI-powered products and ship them end to end on the cloud — most recently Rori, an LLM-driven medical-records assistant. I'm increasingly focused where applied AI meets solid cloud engineering: systems that are reliable, secure, and genuinely useful.

Where I've worked

Jun 2022 — Present Telus International

Backend Software Engineer

Four years building production backend systems across three projects — most recently Telus' recommendation engine. I work inside a Scrum team across the full delivery cycle (design, code, test, document, integrate) alongside QA, architecture and business stakeholders.

  • Building and maintaining the recommendation engine's services on Java & Spring, Node.js / Express, PostgreSQL on GCP.
  • Designed and shipped microservices for a large health-insurance platform, integrating systems over SOAP & REST against Oracle.
  • Earlier, contributed to an open-source collaborative software suite and built tooling for its migration.

Where I'm headed: AI × cloud

My recent work lives at the intersection of applied AI and cloud engineering. With Rori I built a production LLM pipeline end to end — OCR with AWS Textract, then an indexing-and-summarization workflow over Claude (Bedrock) and Gemini (Vertex AI) behind a provider-abstracted service with retry and fallback — running asynchronously on Java virtual threads, fronted by a React/TypeScript app and backed by Terraform-managed AWS infra. It's the direction I'm doubling down on: dependable, secure systems that put modern AI to real, practical use.

  • Production LLM pipelines
  • Multi-provider (Bedrock / Vertex)
  • Serverless on AWS
  • HIPAA-conscious by design

Things I've built

A mix of client work and personal apps shipped end to end — backend, frontend and the parts in between.

Rori

An AI-powered medical Review of Records assistant. Doctors upload PDFs of patient records; Rori runs OCR, indexes each individual record, and generates AI summaries tagged by category and severity — through an async pipeline on Java virtual threads. The LLM layer is provider-abstracted (Claude on Bedrock, Gemini on Vertex AI) with retry and fallback, and it's built HIPAA-conscious from the ground up: per-user data isolation, in-memory tokens, and no PHI in logs.

EOPLAT website

EOPLAT website

A full rebuild for EOPLAT (Eagles of Peace Latinoamérica), a Guatemalan missionary NGO — migrating a 9-year-old WordPress site to a modern stack. A statically-exported Next.js site with a Sanity headless CMS, fronting a serverless AWS backend (Lambda + Cognito) that powers mission-enrollment and a role-based admin dashboard. Deployed on Cloudflare Pages and engineered to run at near-zero hosting cost.

WiMouse remote control app

WiMouse

An all-in-one remote control for your computer: a precise touchpad, media keys and a full keyboard, all from your phone. A cross-platform desktop server receives the input events over WebSockets and executes them locally. Designed to be effortless to set up.

Webcam4all app

Webcam4all

An Android app that turns a phone into a 1080p wireless webcam for Windows or macOS. It captures each frame, encodes it to JPEG and streams it over the local network via HTTP. The real challenge: a low-latency, fault-tolerant stream that still looks sharp.

ECO Library

A library management system built for a private school. Students search the catalog with rich filters and log media usage; administrators manage books, authors, publishers, tags, loans and reports. The hard part was keeping it intuitive enough for the youngest students without sacrificing depth for the staff.

Off the clock: 3D art

When I'm not writing code, I model. I sculpt and texture in Blender and Substance Painter (Cinema 4D in a past life) and sell the results on TurboSquid.
