Hi, I'm Juan.
Senior Product Engineer & Independent Creator
The Journey
I've spent the last 10+ years building software across agencies, startups, crypto products, real-time mobile apps, and scale-up product teams. The throughline is simple: I like taking unclear product needs and turning them into systems that people can actually use.
At Restaurant Brands International, that means working inside production mobile flows where reliability, regional complexity, and team execution matter. Through Entity Builders, it means shaping independent products from idea to architecture, UI, AI orchestration, backend, deployment, and iteration.
How I Work
- Clarify ambiguity I like the early messy part: asking what the product is really trying to make easier, safer, faster, or more delightful.
- Ship useful slices I prefer small pieces that teach us something over large plans that only feel complete on paper.
- Design systems around product needs Architecture should protect the user journey and the business loop, not exist as decoration.
- Use AI as leverage AI is strongest when it compresses real work: parsing, feedback, memory, generation, or decision support.
What I Work With
- Mobile React Native, Expo, iOS & Android
- Backend Node.js, Supabase, AWS, GraphQL
- Data Snowflake, Amplitude, PostgreSQL
- AI Gemini, LLM flows, agents, AI UX
Creative Practice
Outside software, I'm drawn to music, visual ideas, and small creative systems. That side of me shapes how I think about rhythm, taste, constraints, and the feeling a product leaves behind.
I do not see that as separate from engineering. It is part of why I care about product voice, interface feel, and whether a system has a point of view.
Let's Connect
I'm open to thoughtful product engineering conversations, especially around mobile products, AI systems, and ambiguous ideas that need a builder.
