2026Mainjobs
Ingestion and AI layers of a multi-tenant SaaS for public-sector tender tracking.

Multi-tenant SaaS for Spanish public-sector tender tracking · Laravel 12, Filament, MySQL, Redis queues, Forge.
01 · Ingestion
Regional and EU procurement sources, including attachment download behind captchas and rotating proxies. I fixed region- and deadline-parsing defects that were silently hiding thousands of tenders from customers’ search results.
02 · AI layer
A versioned registry resolves provider and model across OpenAI, Anthropic and Gemini, with fallback when a provider has no credentials, per-model cost tracking and threshold alerts. It replaced a setup where one missing environment variable silently ran the most expensive model at roughly 10x the cost.
03 · Product
An LLM proposal generator with per-company knowledge sources, plan-based quotas and queued generation, so a long job never blocks a request. Large modules ship behind feature flags, in parts.
04 · Performance
I restructured the ordering and pagination path of the main tender listing query.
How I work
I work daily with Claude Code and Codex. Their output goes through what any other code goes through: tests, static analysis and review. And it gets reverted when it is wrong.
Before calling a fix done, I undo it and check that the test goes red.
Larastan catches missing classes and methods before they reach production.
Feature flags let large modules go out without waiting for everything.
Encoding corruption in extracted PDFs, pagination and timezones: what nobody sees until it breaks.
Side project
What a car trip really costs, split between the people in it.
It computes the real cost of each trip, including the effect of elevation gain and the ceiling on how much of a descent a hybrid’s battery can actually absorb.
It splits the cost with double-entry bookkeeping: every trip is a journal entry whose lines sum to zero, enforced by a deferred PostgreSQL trigger. No script can unbalance the ledger, and money is integer cents throughout.
Live distance and elevation from OpenRouteService, degrading in steps when a free quota runs out, plus official ministry fuel prices.
