Frequently Asked Questions
Common questions about working with me as your ML/AI engineer.
What kind of AI/ML projects do you work on?
I specialize in LLM-powered applications (chatbots, RAG pipelines, agentic AI), computer vision systems (object detection, OCR), and end-to-end ML pipelines. From data preprocessing to production deployment.
Do you work remotely?
Yes, I work fully remote. Based in Pakistan, but available for clients worldwide. I maintain clear communication across timezones with regular check-ins and structured milestones.
What's your typical project timeline?
It depends on scope: small ML models or chatbot integrations take 1-2 weeks. Full AI systems with custom training and deployment typically take 1-3 months. I provide a clear timeline upfront.
What's your tech stack?
Python is my primary language. For ML: PyTorch, TensorFlow, Scikit-learn. For NLP/LLMs: HuggingFace, LangChain, LlamaIndex, SpaCy. For deployment: FastAPI, Docker, AWS. I adapt based on project needs.
How do you handle pricing?
I offer both fixed-price and hourly options. For well-defined projects, I provide a fixed quote upfront. For ongoing or evolving work, I bill hourly with weekly progress reports. All pricing is discussed before starting.
How do we communicate during the project?
I use Slack, Discord, or WhatsApp for daily chat. Weekly video calls for progress reviews. You get access to a shared project board (Notion or GitHub Projects) so you always know exactly where things stand.
