ObjectSingle Unipessoal Lda

Senior AI engineering. Shipped in weeks, owned by you.

Overview

We build custom AI systems and automation for B2B and eCommerce teams. Own AI on your data and workflows instead of renting more SaaS. Production grade, shipped in weeks. ObjectSingle is a Lisbon-based engineering team, led by a developer with 9+ years building production software. Most AI freelancers fall into two camps: no-code tools wired together that break under real load, or researchers who never ship. We are neither. We build real AI systems and the software around them, deployed, integrated with your stack, and handed over so your team can run them. ๐—ช๐—ต๐—ฎ๐˜ ๐˜„๐—ฒ ๐—ฑ๐—ผ ๐—”๐—œ ๐—ฎ๐˜‚๐˜๐—ผ๐—บ๐—ฎ๐˜๐—ถ๐—ผ๐—ป: We take a manual, repetitive workflow and run it with an AI agent connected to your tools and data.
