I build intelligent applications powered by OpenAI, ChatGPT, Claude, Gemini, LLaMA, and Mistral. My expertise includes LLM fine-tuning, prompt engineering, AI agents, multi-agent systems, AI assistants, AI workflows, function calling, and tool use. I design and implement RAG pipelines (Retrieval-Augmented Generation) using vector databases like Pinecone, Weaviate, ChromaDB, and FAISS for document intelligence and enterprise knowledge bases.
Generative AI Applications
Content generation, text summarization, embeddings, semantic search, AI writing tools, AI copilots, and custom GPT solutions. I build Generative AI products that integrate directly into your business workflows.
Machine Learning & Deep Learning
Predictive analytics, recommendation systems, anomaly detection, classification, regression, time-series forecasting, and NLP solutions including text classification, named entity recognition (NER), sentiment analysis, and document processing pipelines.
Computer Vision
OCR systems, object detection, image classification, image processing pipelines, and document AI, built with OpenCV, YOLO, TensorFlow, and PyTorch.
AI Automation & Integrations
I connect AI models with real business systems using n8n, Zapier, and Make. This includes CRM integrations, SaaS tool automation, Stripe, PayPal, and internal workflow automation, reducing manual effort and scaling operations intelligently.
Backend & API Engineering
Scalable AI APIs, data pipelines, inference systems, and cloud-ready backend architectures using FastAPI, Flask, Django, REST, and GraphQL. I handle the full AI lifecycle: data processing, feature engineering, model training, deployment, and production integration.

I build web scrapers and backend systems that run reliably in production, so you're not the one debugging them at midnight with AI/LLM integrations layered in where the project calls for it.
I work with startups and growing teams who need something specific built and shipped, not a generic dev shop. Scraping pipelines, backend APIs, automation workflows, AI integrations I've built all of these in production, not in a tutorial.
A few things I've actually shipped:
✅ Scraped 10,000+ business records with Python/Selenium, piped through AWS
Lambda into DynamoDB and RDS running unattended for a live client
✅ Built a Pinecone + LangChain recommendation engine with semantic search
over embedded text data
✅ Built a real-time chat system: WebSocket gateway + RabbitMQ across
microservices
✅ Built a gRPC payment microservice for secure transaction handling
✅ Shipped NestJS REST APIs with JWT auth, cutting response times through
clean query and caching design
✅ Ran a Python/Selenium scraping framework for a German B2B SaaS company
(Markt-Pilot) still an active client
100% Job Success Score. Top Rated. Karachi-based, but I work async-friendly
hours for US/EU teams.
If you've got a backend, scraper, or AI workflow that needs to actually work
in production send me the details and I'll tell you straight whether it's
a good fit, no sales pitch.
EXPERTISE: NestJS | Node.js | Python | Selenium | BeautifulSoup | AWS

I am a computer engineer and AI-focused backend developer with more than a decade of experience in education, research, and real-world system building.
Since 2013, I have worked as a professor at Universidad Técnica del Norte, where I have taught computer engineering and helped grow many highly capable engineers now working in industry. Alongside teaching, I have continuously expanded my expertise in challenging areas such as artificial intelligence, machine learning, and large-scale system design, building a strong and practical technical foundation.
My work sits at the intersection of AI, backend engineering, automation, and data. I help teams take unclear ideas, raw data, or manual workflows and turn them into clean, reliable, production-ready systems that work day to day.
On the AI side, I focus on practical LLM applications rather than demos. This includes RAG pipelines, multi-agent systems, chatbots with memory, document processing, semantic search, classification, extraction, and automation workflows. I have hands-on experience with LangChain, Hugging Face, OpenAI, Claude, and vector databases such as Pinecone and FAISS, including fine-tuning when it makes sense. My priority is always usefulness, reliability, and maintainability.
Backend engineering is a core strength. I design and build APIs, services, and data pipelines using Python with FastAPI, Flask, and Django. I care deeply about clean architecture, performance, and systems that are easy to extend and maintain over the long term.
I also have a strong background in automation and data engineering. I have built web scrapers, crawlers, ETL pipelines, data cleaning systems, reporting tools, dashboards, and bots for years. My focus is on stability and resilience, not fragile scripts that break after a short time.
Deployment and infrastructure are part of my workflow, not an afterthought. I regularly deploy and operate systems on AWS, GCP, and Azure, using Docker, CI/CD pipelines, and serverless or containerized architectures depending on the project’s needs.
I have worked with universities, companies, startups, and individual founders, often acting as a technical partner rather than just a task-based freelancer. I take time to understand the business goal first, then design a technical solution that fits it.
I joined Upwork in 2016 out of interest and haveused the platform just to enjoy my creative hobby projects such as design and visual work, not for my major.
But always, I couldn't spare time for it.
Over the years, I closely followed the platform’s growth and always wanted to collaborate with global clients.
I recently retired from my academic-related work and can now dedicate myself to professional freelance activities.
What you can expect when working with me:
- production-ready AI and backend systems
- clear communication and realistic estimates
- strong ownership and responsibility
- solutions designed to scale and last
If you are looking for someone who can combine AI, backend engineering, automation, and data into one solid, dependable system, I would be glad to work with you.
