I build AI voice agents that answer, qualify, and book — on real phone lines. 9+ years of full-stack engineering plus a telephony background (SIP/Asterisk), so your agent doesn't just demo well, it survives production traffic.
Most voice agents break in the same three places: latency, call transfers, and everything that's supposed to happen after the call ends. I handle all three.
⭐ Top Rated · 100% Job Success · 45 contracts · 650+ hours · zero disputes
━━ WHAT I BUILD ━━
🎙️ AI Voice Agents
• Inbound reception, outbound lead calls, appointment booking, lead qualification
• Vapi, Retell AI, ElevenLabs, OpenAI Realtime — STT/TTS pipelines tuned for sub-500ms response
• Prompt + call-flow design that handles interruptions, accents and background noise
☎️ Telephony That Actually Connects
• Twilio, SIP trunking, Asterisk / FreePBX, DID provisioning
• Warm transfers to human agents, IVR replacement, call recording & compliance
• Debugging the layer most "AI agent" developers can't reach
🔗 Post-Call Automation
• CRM writeback — GoHighLevel, HubSpot, Salesforce
• n8n, Make, Zapier workflows · transcripts, summaries, follow-up SMS & email
💻 The App Around The Agent
• Next.js, React, TypeScript dashboards · call analytics & admin panels
• Node.js, Express, Laravel, PHP APIs · AWS, Docker, PostgreSQL, MongoDB
━━ WHY CLIENTS KEEP ME ━━
Since 2019 I've led engineering at Global Voice Direct, a voice/telecom company. I was debugging codecs, jitter, SIP registration failures and carrier routing long before "AI voice agent" was a job title. So when your Vapi agent drops calls, talks over people, or won't hand off to a human, I can tell you whether it's the prompt, the API, or the carrier — usually on the first call.
━━ RECENT WORK ━━
• AI employee & business automation platform — iThinq AI
• Creator monetization SaaS platform — PrimeFirre
• $8.6K PHP / Symfony microservices + REST API build
• 45 Upwork contracts delivered at 100% Job Success
━━ HOW I WORK ━━
Replies usually within the hour. A written plan before I touch code. And a working number you can actually call before we go live.
Message me with what you want the agent to do on the phone. I'll tell you in one reply whether it's a 3-day build or a 3-week build — and what it will cost.

Building a connected product is hard. It requires expertise across hardware, embedded systems, mobile applications, cloud infrastructure, AI, and the ability to bring all of those pieces together into a production-ready solution.
That's where I help.
I work with startups, scale-ups, and enterprises to architect and build connected products—from embedded devices and IoT platforms to AI-powered mobile applications and scalable cloud infrastructure. Whether you're building a connected vehicle platform, a medical device, an industrial IoT solution, or the next generation of smart products, I can help take it from concept to production.
Over the past 15+ years, I've delivered production software across Connected Vehicles, Telematics, MedTech, Industrial IoT, Transportation, and Enterprise Mobility.
Before founding LogiQlink Technologies, I spent over 12 years at Treeline Interactive in San Diego, progressing from Senior Mobile Engineer to Mobile Tech Lead and eventually Head of India Operations. During that time, I worked directly with US startups and enterprises, leading distributed engineering teams and delivering complex connected products used in production.
Today, as Founder and Director of LogiQlink Technologies, I continue to help companies build connected products by combining deep technical expertise with hands-on engineering leadership.
CORE EXPERTISE
Connected Products & IoT
• End-to-end connected product development from hardware prototyping to cloud deployment
• Embedded Linux, AOSP, and Android Automotive OS (AAOS)
• BLE, CAN Bus, MQTT, sensor integration, and industrial communication protocols
• Device connectivity, real-time data pipelines, and remote device management platforms
AI & Intelligent Systems
• AI-powered features for mobile and connected devices
• Machine learning integration and on-device inference
• Computer Vision, predictive analytics, and intelligent automation
Cloud & Backend
• AWS and Firebase architecture, deployment, and scaling
• REST APIs, GraphQL, backend development, and real-time systems
• Event-driven architecture, CI/CD, and scalable cloud infrastructure
Mobile Applications
• Native Android (Kotlin/Java) and iOS (Swift)
• React Native and Flutter
• Production mobile applications for connected products, MedTech, transportation, and enterprise platforms
HOW I ENGAGE
Fractional CTO
I help startups define technical strategy, architect scalable platforms, build engineering teams, and make critical technology decisions without the cost of a full-time CTO.
Solution Architect
I design scalable systems from the ground up—including cloud architecture, hardware-software integration, APIs, and connected product platforms—so your team starts with the right technical foundation.
Hands-on Engineer
I still enjoy building products. Whether it's a mobile application, embedded firmware, an IoT platform, or a cloud backend, I write clean, maintainable, production-quality code.
Engineering Leader
I've built and managed distributed engineering teams across the US and India and can help recruit, mentor, and scale engineering organisations for long-term success.
WHO I WORK WITH
• Startups looking for a technical co-founder or Fractional CTO
• Product companies building connected devices and IoT platforms
• Automotive, fleet, and mobility technology companies
• Medical device and digital health companies
• Industrial IoT and enterprise software teams
Whether you need a Fractional CTO, Solution Architect, or hands-on engineer, I bring the technical depth to build production-ready systems and the leadership experience to turn ambitious ideas into successful products. If you're building a connected product, I'd love to discuss how I can help.
