Zakir K.

I build human-like AI voice agents on Pipecat: natural, low-latency calls that handle interruptions and accents, speak 50+ languages, book live, never make things up, warm-transfer, log to your CRM. I run this stack in production at SpeakEdge.ai, my own AI receptionist platform, answering real calls on the web, right from a website, and over the phone via SIP (Twilio, Plivo, Exotel). If you're building your own voice AI product, or want to leave per-minute platforms like Vapi or Retell and keep call data in your own infrastructure, that's exactly what I do. Most voice AI demos sound great and fall apart on live calls. I know what it takes to make them hold up, because I built and run my own platform handling real customer conversations. WHAT I BUILD • Self-hosted voice AI stacks – Pipecat pipelines you own, running in your own cloud, for teams cutting per-minute costs or with data-control rules (legal, healthcare, finance) • Voice AI platforms for SaaS founders – multi-tenant, white-label AI receptionists for one industry. I can license my production voice core so you start from a working system. • AI receptionists – 24/7 inbound call answering, FAQs, appointment booking, call routing and live transfer to your team • Outbound AI calling agents – lead qualification, speed-to-lead callbacks, follow-ups, reminders and reactivation campaigns • AI automation workflows – calls, transcripts and lead data synced to your CRM, calendar, email, SMS and WhatsApp so nothing slips through the cracks • Knowledge bases and RAG that stop AI agents misquoting prices or making up answers • Call analytics – transcripts, summaries, lead scoring, sentiment and call attribution WHAT YOUR CALLERS GET • Natural, human-like conversation – handles interruptions (barge-in), pauses, accents and background noise without sounding like an IVR • Fast replies – low-latency streaming, with no dead air while the agent books or looks something up • Real actions, never made up – books, reschedules and cancels in your live calendar, and only confirms what actually succeeded • Warm transfer to your staff, plus after-hours routing and safe fallbacks • Multilingual – 50+ languages, including Hindi and other Indian languages, so callers can speak their own language • Production-ready – transcripts, summaries and recordings sent to your CRM, configurable per client (multi-tenant), with data kept in your own infrastructure for HIPAA/GDPR needs PRODUCTS I'VE BUILT AND LAUNCHED • SpeakEdge – AI receptionist and voice agent platform on self-hosted Pipecat that answers, qualifies and books enquiries across phone, website and WhatsApp • KB Builder – turns a business's website, documents and notes into a knowledge base AI voice agents and chatbots answer from accurately, ready for Vapi, Retell AI, ElevenLabs, Chatbase and other platforms WHY CLIENTS HIRE ME • 18+ years of software engineering and a Director of Technology, so you get architecture, not just prompts • Production experience: voice agents live in hospitality and healthcare businesses today • Sub-300ms response latency, so conversations feel natural and callers don't hang up • I integrate with the tools you already use instead of forcing a new stack on you • Clear communication and full overlap with US East Coast mornings and UK/EU business hours STACK Pipecat (self-hosted) • SIP telephony via Twilio, Plivo and Exotel • Deepgram and Sarvam speech-to-text • OpenAI and Gemini LLMs • ElevenLabs TTS • TypeSafe AI Jev for structured decisions • Python • Google Calendar, CRM, email and WhatsApp integrations HOW I WORK 1. Discovery call to map your call flows and where revenue is leaking 2. A working prototype you can phone and test within days 3. Production rollout with monitoring, call reviews and ongoing tuning Best fit: SaaS founders building their own voice AI product, teams that need a self-hosted stack, and businesses that rely on the phone for revenue – clinics, home services, real estate, hospitality, legal, agencies. I focus on doing it properly, not on being the cheapest option.
