    OrigenLab

    Commercial software for a laboratory-equipment business: public site, email intelligence pipeline, operator API behind a Cloudflare Worker, CRM dashboard, and a Supabase V2 data platform under migration

    One system that finds demand, records counterparties, tracks each pursuable sale, produces quotations, and sends email under strict safety controls. V1 runs today as an Astro site, a SQLite-first Python pipeline, a FastAPI operator API over PostgreSQL, a Cloudflare Worker proxy, and a React CRM. V2 moves it onto one Supabase PostgreSQL project with a single command boundary.

    Heavy Ops

    B2B platform matching heavy-equipment companies with eligible, compliant machine operators, with an explainable arrival-bonus workflow

    Chile-first platform where a company publishes a structured operator request, the system checks machine capability, verified credentials, availability, radius, and booking conflicts before anyone sees it, and only eligible operators receive the opportunity. An optional arrival bonus rises within a company-set band until acceptance and freezes there.

    BENKER Commercial Platform

    Pre-production platform for a heavy-civil-works estimating business: organisations, studies, quotations, approvals, outcomes, and marketing eligibility on one identity layer

    Replaces fragmented spreadsheets, a quotation PDF archive, and Drive folder workflows with a reliable record of what is in the pipeline, what was quoted, and what the outcome was. Two subsystems, commercial and marketing, share one identity layer.

    Geospatial and forestry monorepo: LiDAR timber-stack measurement, forestry GIS management, and shared PostGIS platform services

    Multi-product platform for a Chilean forestry and geospatial services company: point-cloud processing and volume estimation for timber piles, a forestry GIS product for properties, stands, and partial harvests, a separate utilities-sector application domain, and a local company portal that composes all three.
