If you want to build an IoT product for your customers or if you want to automate your business or factory processes using IoT solutions. Or, if you want to reduce your labor cost by using modern technologies, then you're in the right place.
I create complete solutions to make your processes automated. I can create firmware for different hardware like ESP32, ESP8266, or Raspberry Pi, etc.
I can also use the cloud services like AWS IoT, Azure, or Google cloud to build modern IoT solutions. We can connect and control our hardware using an Admin Panel, Mobile Application, Alexa, or Google Home by using voice commands or using manual interaction.
We can use different sensors to achieve our goal like
Temperature Sensor
Proximity Sensor
Accelerometer
IR Sensor (Infrared Sensor)
Pressure Sensor
Light Sensor
Ultrasonic Sensor
Smoke, Gas, and Alcohol Sensor
Touch Sensor
Color Sensor
Humidity Sensor
Position Sensor
Magnetic Sensor (Hall Effect Sensor)
Microphone (Sound Sensor)
Tilt Sensor
Flow and Level Sensor
PIR Sensor
Touch Sensor

AI Voice Agent for Inbound Calls
It was a pleasure working with Awais on our AI voice agent project. He built a production-ready inbound voice solution by integrating Twilio, ElevenLabs, and OpenAI, and delivered a smooth, natural-sounding customer experience throughout. His technical depth in AI and voice technology was evident from day one, and he handled the complexity of connecting multiple platforms with confidence and skill. Communication was clear and timely, and he was responsive to feedback at every stage. I'd happily recommend him to anyone looking for a knowledgeable and reliable AI voice developer.

Most AI developers can build a demo. I ship systems that survive real users, real call volume, real revenue, and strict SLA requirements.
šļø šš ššØš¢šš šš šš§šš¬ (ššØš«š šš©ššš¢šš„šš²)
End-to-end AI voice agents and AI receptionists: inbound and outbound calling, appointment booking, lead qualification, real-time transcription, sentiment analysis, CRM integrations (GoHighLevel, HubSpot, custom), and human handoff flows.
ā Vapi, Retell AI, Bland when you need fast platform-based deployment
ā Custom Twilio + Deepgram + ElevenLabs pipelines when you need full control over latency, cost, and conversation logic
ā OpenAI, Claude, and open-source LLMs for the conversational layer
Recent work: HopDial, a VoIP platform with call transcription, AI sentiment analysis, and scalable AWS infrastructure, plus outbound AI calling systems and AI receptionists for SMBs and service businesses.
š ššš, ššš & šš šššš
I run my own production products, so I know what breaks at scale and what actually generates revenue:
ā Legal AI platform: production RAG system (LangChain + vector search) serving ~4,000 active users
ā ProNotepad: Next.js SaaS with AES-256 encryption, voice-to-text, and AI features. 1,000+ users on web and Android
ā WhoseNo: reverse phone lookup platform with 2.68M+ phone records and steady daily traffic
ā WhatsApp-first AI business automation platform, plus AI chatbots for web and WhatsApp
Client work includes real estate transaction platforms (Next.js), pharmaceutical marketplaces (React Native + NestJS), and private dining and booking platforms.

1. Founders building serious voice AI or AI SaaS products
2. SMBs and service businesses (clinics, real estate, agencies) that want AI calling agents to book appointments and convert leads
3. Funded startups scaling from prototype to production
4. Agencies needing a senior AI and architecture partner
5. Teams on Bubble that want real AI and backend systems behind their app
12+ years means I've already made the expensive mistakes, so you don't have to. You get clean architecture, honest timelines, and production-ready systems your next developer won't struggle to maintain.
If you're building something serious with AI voice agents, RAG, LLM apps, or AI SaaS, send an invite and share your idea. I'll respond with a technical breakdown, not a generic pitch.
