Rawalpindi, Pakistan - 2:54 pm local time
I am a Senior Full Stack Engineer specializing in Distributed Systems, Backend Development, and Production Voice AI. I design high-throughput, resilient software architectures for businesses that require robust, enterprise-ready systems—not brittle demos.

The scope of my services bridges advanced AI Integration with deep Cloud Architecture. I integrate AI agents, computer vision pipelines, real-time media streams, and complex business logic into scalable production solutions that handle real-world traffic without downtime.

🛠️ Core Technical Competencies

• Production Voice AI & Audio Engineering
Architecting sub-second latency voice systems, outbound AI calling platforms, and automated phone receptionists. Expert in Twilio, Vapi, Daily, ElevenLabs, WebSockets, WebRTC, TTS/STT pipeline development, custom call flow design, and CRM-based webhook automation.

• AI Agents & Event-Driven Automation
Building autonomous multi-agent systems using the OpenAI Assistants API, ChatGPT API integration, advanced tool-calling protocols, dynamic CRM integrations (GoHighLevel, HubSpot), and async webhook pipelines for business process automation.

• Backend Development & Database Architecture
Engineering robust backend microservices and APIs using Python, FastAPI, Node.js, and TypeScript. Designing scalable database models with PostgreSQL, Supabase Vector Search, and Redis caching layers. Implementing containerized workflows using Docker and Cloud Architecture.

• Computer Vision & Data Extraction Pipelines
Developing high-precision visual processing engines, document data extraction pipelines, image recognition, and real-time object tracking systems using OpenCV, Tesseract OCR, Google Cloud Vision API, and Azure AI Vision.

• Real-Time Media & Web Automation
Implementing low-latency real-time communications platforms, media streaming synchronization, and automated browser workflows via Playwright distributed on Runpod GPU instances.

📈 Proven Production Track Record

• SaaS Development & Multi-Tenant Architecture: Developed end-to-end voice workflow engines and automated scheduling software for specialized trade and service companies.
• Data Engineering & Audio Processing: Deployed event-driven machine learning speech-to-sentiment audio pipelines capable of processing continuous data streams in production.
• Database Performance Optimization: Designed highly optimized database architectures utilizing Supabase and PostgreSQL for high-precision, low-latency search indexing.
• Infrastructure Troubleshooting & Fixes: Rescued broken real-time chatbot pipelines, fixed WebRTC/WebSocket communication drops, and resolved complex backend synchronization issues.

🎯 Ideal Project Fit

I am an elite technical match for companies looking to embed AI into the core of their software products. Whether you need a tool-using AI agent framework, a low-latency voice system handling live enterprise calls, a high-volume vision pipeline, or a stable distributed backend that keeps everything running under pressure—I can help you design, develop, debug, and deploy it.
