Cloud Strategy

AWS Serverless · Lambda

Serverless architectures with Lambda, API Gateway, S3, and RDS — plus CI/CD via GitHub Actions and Azure DevOps.

AI Builder

RAG · Agents · Copilots

Production RAG pipelines, AI agents, and ML analytics — plus daily use of Cursor and Claude Code for SDLC acceleration.

Web Craft

.NET · React · Clean Architecture

Full-stack platforms with C#/.NET 10+, React/TypeScript, Entity Framework Core, and Aurora MySQL — built with Clean Architecture and DI.

01 · Projects

Product initiatives I've led end-to-end

I prototype platforms that blend human-centered design with AI and cloud to unlock measurable outcomes.

Desku

Next.jsTypeScriptPrismaSQLitePlaywrightCheerio

One place for every merchant promo (restaurants, stores) based on the credit/debit card you own. Scrapes BCP, Interbank and Falabella promo sites, normalizes them into a local SQLite database and indexes each promo per card in an O(1) in-memory cache — so 'what promos do I get with my card?' answers instantly.

Instant per-card promo lookups from scraped bank and retail data, fully local and private.

QuartoPress

Next.jsTypeScriptTailwindPandoc WASM

Browser-only converter that turns Quarto (.qmd) and Markdown documents into HTML, PDF and Jupyter notebooks using Pandoc compiled to WebAssembly.

Documents never leave the device: 100% local conversion with auto-detected R, Python or Julia kernels.

NotchFX

SwiftObjective-CShell

Brings your MacBook notch to life as a dynamic island — timers, battery alerts, and more with real physics and natural gestures.

Native macOS utility that transforms the notch into an interactive, physics-driven UI layer.

TZ Flows

TypeScriptNode.jsPlaywrightAWSYAML

CLI toolkit that augments AI agents (Claude Code, Grok Builder) with structured automation — browser orchestration via Playwright, Jira/GitHub integrations, and composable skill workflows for repetitive engineering tasks.

Engineers ship repetitive tasks faster by replaying documented, battle-tested skill workflows (40% faster card setup).
