US-based senior software engineer, Pacific time, available now for contract work (part time or full time). Seven years as the backend owner of a multi-tenant B2B SaaS that grew from about $4M to $13M ARR, plus my own live product since June (a voice-recording app for assisted living with a speech-to-text and LLM pipeline behind it). What people usually bring me: An app that is 80% done and won't ship. Built with Lovable, Bolt, Cursor, or an agency that disappeared. I read the code, write down what is actually broken, fix it, and get it launched: auth, payments and subscriptions, database security, deploys. AI features that have to work when nobody is watching. LLM calls, voice and chat agents, document pipelines, evals for "is the model's answer actually right", with retries, logging and a plan for when the model is wrong. Old or slow codebases. Framework upgrades several major versions behind, slow pages and queries, moving off an expensive host. My day job runs on a ~1 TB database, so I care a lot about not taking things down while fixing them. Fixed-scope reviews. Security or architecture review of a codebase you inherited, with a written list you can act on. Work and live projects: https://consulting.levelbrook.com Rate: $100/hr, or a fixed price once I've seen the code. Send a PM with what you have and where it's stuck and I'll reply with a short plan.   submitted by   /u/levelbrook [link]   [comments]
