Missed calls and slow follow-up cost businesses real revenue, especially after hours when nobody is there to pick up. I build voice AI agents and agentic automation that run live in production and handle those calls, bookings, and follow-ups. What I’ve done: 1) Lead developer on VoiceCake, a 24/7 inbound voice AI platform answering around 2,000 calls a week for dental, healthcare, fitness, and mortgage clients (booking, triage, lead capture). 2) At Rawk.ai, cut a voice agent platform’s average request time from about 900 ms to about 320 ms. 3) At Dynaris, built multi-step agent workflows across Gmail, Google Calendar, CRMs, and Slack. 4) Built a fixed-price, milestone-gated trading platform with live broker integrations. Four years of production work, Top Rated Plus, 100% job success. What clients say: “Jareer is an exceptional talent.” Another client credited my work on their LiveKit-based voice agent, including custom functions and knowledge-base integration. Stack: LiveKit, Twilio, Retell AI, Vapi, Deepgram, ElevenLabs, Python, FastAPI, LangChain, LangGraph, MCP, RAG, Pinecone, PostgreSQL, HubSpot, Salesforce, Zoho. How I work: I ship a change, test it against real scenarios, log what breaks, fix it, and repeat. I own the work from design to production and reply within a few hours. Send me your stack and what you want the agent to do, and I’ll tell you what it needs.
