01
AI & data systems
Semantic search, computer vision, AI-assisted workflows, data processing, geospatial analysis, and evaluation.
AI SYSTEMS · AUTOMATION · PRODUCT ENGINEERING
Software that moves work forward.
I design and build AI-powered systems, automation, and software for marketing, sales, media production, operations, and data.
About
Former founder/CTO, product engineer, and engineering leader with more than 20 years building software products from the first product decision through architecture, delivery, and growth.
I start with the outcome, look for the smallest useful change, and let complexity earn its place through real use. I’m at my best when the problem is clear but the path is not. A lot of speed comes from deciding what not to build. I repurpose existing systems beyond their original purpose when that solves the problem faster and keeps the solution easy to change.
I treat agentic development as more than a productivity tool. Because generated output is probabilistic, I don’t rely on prompts or rules files alone; correctness comes from explicit acceptance criteria, deterministic checks, tests, evaluation, and human review.
What I build
Three connected kinds of systems.
02
Marketing performance, sales & automation
CRO, growth experiments, CRM, lead routing, enrichment, customer win-back, publishing, and reporting.
03
Creative & media production systems
Product content, automated video, distributed rendering, and controlled workflows for generative media.
Selected projects
Systems built around practical problems.
Automated video production
Template-driven video production with centrally coordinated distributed rendering.
AI image search
Semantic image retrieval through computer vision and vector search.
Brevy
Deterministic product-information graphics rendered from reusable HTML templates.
Wildfires & environment
Non-profit work on wildfire prediction, prevention, and environmental monitoring.
Open source & writing

Selected projects
Volt — Built a product and engineering system that measures progress by how much a business gap closes, rather than by task completion. Connects each gap to hypotheses, work, and observed results.
WildfireOS.org — Personal non-profit project using satellite and environmental data for wildfire monitoring, prediction, and treatment planning in Portugal and the Mediterranean.
AI Search & Computer Vision — Built semantic and image-search prototypes using Qdrant, Typesense, and computer-vision pipelines.
