Backend (Nodejs, PHP, Express, Koa, Hapi)
I'll write efficient, low latency APIs for your backend system and deploy them on AWS Lambda, or any other cloud system. I'll write APIs using NodeJS and serverless framework.
I can also create APIs without using the serverless framework as well so you should be able to deploy them anywhere. I can help you with deployment as well wherever you want to deploy it.
I can help you with other AWS services like AWS API Gateway, SES, S3, SNS, Cognito, Transcoder, and other services of other Cloud platforms like Google Cloud, and Azure.
Why you should work with me?
- Efficient performance
- Low latency
- Using best practices
- Using Nodejs latest version
- Robust and extendable
I can also help you with the integration of the APIs in Admin Panel, Website, Android, or iOS application.

Build Production-Ready AI Voice Agent for Inbound Calls Using Twilio, ElevenLabs, and OpenAI
Excellent developer to work with. He understood the project requirements clearly from the start and made scoping the AI voice agent straightforward.
Communication was prompt and professional throughout, and he was responsive whenever clarification was needed about the work done. He recommended the right tech stack, including Twilio, OpenAI, ElevenLabs, and Node.js, and showed strong technical judgment.
The collaboration was smooth, testing and feedback were handled well, and the overall delivery met expectations. I would happily work with him again on future voice agent or backend projects. Highly recommended.

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.

Job Success
Lahore, PakistanĀ - 11:17 pm local time
If you need an AI receptionist that handles inbound calls 24/7, an outbound voice agent for lead qualification and follow-ups, or an LLM assistant grounded in your own documents, this is the exact work I do every day.
WHAT I BUILD
AI Voice Agents (Vapi, Retell AI, Twilio, Deepgram, ElevenLabs)
ā¤ Inbound AI receptionists: call answering, FAQs, appointment booking, smart transfer to a human when needed
ā¤ Outbound agents: lead qualification, appointment reminders, follow-up calls
ā¤ Real-time call transcription, sentiment analysis, voicemail detection, and call summaries pushed to your CRM
ā¤ Telephony done right: SIP trunking, call routing, recording, and compliance-aware setups
RAG and LLM Systems (AWS Bedrock, Claude, GPT, LangChain, pgvector)
ā¤ Retrieval augmented generation over large corpora: chunking, embeddings, vector search, reranking
ā¤ Document Q&A assistants and AI chatbots that cite sources instead of hallucinating
ā¤ Ingestion pipelines with OCR (Textract), queues (SQS), and cost monitoring
Full-Stack Delivery
Node.js, NestJS, FastAPI, Python, Next.js, React Native, PostgreSQL, MySQL, Redis, Docker, AWS (EC2, RDS, Bedrock, SQS). I ship the voice AI agent, the automation around it, and the product it lives in: dashboards, auth, billing, analytics.
SELECTED WORK
š¢ SlayAI (legal AI platform): architected the RAG pipeline serving ~4,000 active users over a 300GB+ legal document corpus on AWS Bedrock, pgvector, SQS, and Textract. 97% answer accuracy in internal evals, with automated document ingestion and readiness checks.
š¢ HopDial (VoIP + AI calling platform): built live-call AI transcription and sentiment analysis on Twilio infrastructure with Deepgram STT and ElevenLabs TTS.
š¢ WhoseNo (my own product): high-traffic phone intelligence platform with 5.79M+ records, MySQL and Redis at scale behind Cloudflare, plus a companion Android app.
WHY CLIENTS KEEP ME
96% Job Success across 178 reviews. Most of my work turns long-term: clients bring me in for one agent, and I end up owning their AI roadmap. I communicate daily, demo early, and never disappear.
