WhatsApp lead automation engine

Group Quimera

Leads arrived over WhatsApp and were processed by hand: someone copied them into the CRM, classified them and assigned them. Time was lost, and so were leads.

I built an n8n workflow that receives the message through the WhatsApp Business API, extracts and validates the data, syncs it to the CRM and PostgreSQL in real time, and notifies the right salesperson.

Outcome: 40% reduction in processing time per lead.

Corporate data warehouse and ETL pipelines

Gerona SVF

Sales, inventory and CRM lived in separate systems. Reports were assembled by hand and nobody entirely trusted the numbers.

I designed ETL pipelines with Python, Airflow and dbt processing millions of daily records into Snowflake and BigQuery, over a warehouse using star and snowflake schemas, plus Power BI dashboards and automated alerting.

Outcome: 50% faster load times and 95% report reliability.

Casera: digital ledger for market vendors

My own product

Market vendors in Santa Cruz track sales, expenses and customer credit in a paper notebook. If the notebook is lost or ruined, the business goes with it.

An offline-first PWA built for cheap Android phones, centred on customer credit: who owes, how much, and since when. No account, no internet required.

Mesa Abierta: board game tables by the seat

My own product

Board game venues only rent tables to groups that arrive together. Anyone who wants to play without a group has nowhere to sit.

A multi-venue platform where solo players claim a single seat at an open table, groups book the whole table, and the venue runs the operation.

E-commerce operations automation

US client: toys and sports accessories

An e-commerce operation with repetitive work spread across the store, suppliers and customer service, plus an outdated web presence.

I built n8n automation workflows for the repetitive work and refreshed their web presence. The entire engagement was run in English, end to end.

CRM workflows and landing pages for home automation

US client: automated curtains and window systems

A sales team with no structured follow-up and no capture pages behind their campaigns.

I configured the CRM workflows and built the landing pages supporting their sales operation.
