Swaleheen J.

I build production AI agents, LLM apps and voice AI that survive real users. 9,400+ Upwork hours, 100% Job Success, Top Rated Plus, and most clients keep me for months. Most AI demos work once. I build the version that runs at 2am with nobody watching: retries, timeouts, rate limits, token cost, silent failures, and the edge case nobody specified. I write the code myself and work directly with your team. No account managers in between. How I work (AI-native, human-owned) I use Claude Code / Cursor every day to plan, build and review. I break features into scoped tasks for coding agents, review every line they produce, and write the parts where direct coding is faster or safer. I test against the running app, not just the type checker.
