Leonardo N.

Senior Ecommerce Engineer

I build and maintain ecommerce stores that need more than a theme and a few plugins. Today I own the code and the production infrastructure of 8 ecommerce stores for a US company, and I'm the principal developer of Siren Affiliates, an affiliate SaaS with 100+ clients, integrated with WooCommerce, BigCommerce and North Commerce. What I can do for your store: Custom WooCommerce and WordPress plugins, when the off-the-shelf one doesn't fit. I've shipped 30+ of them in PHP, TypeScript and React. Integrations with the tools your business runs on: Stripe, HubSpot, Google Maps, REST APIs and webhooks. Performance and hosting. I moved a production platform from WP Engine to DigitalOcean with Redis and Cloudflare, and the bill went from $5,000 to under $200 a month. Fixing what is already broken: slow checkout, plugin conflicts, failing syncs, errors nobody can explain. Maintenance with tests. One example: a moving company priced every job from a spreadsheet. I built a quoting tool with Google Maps and HubSpot, so the price is calculated on the spot and the lead lands in the CRM. How I work: I ask what the store needs to sell more or spend less, before I write code. I send short written updates, and I leave the project documented so you are not locked to me. I'm based in Brazil, English C1, with good overlap with US time zones. Send me what's going on with your store and I'll tell you how I would approach it.
