Frequently asked questions

I'm a freelance data scientist and AI engineer. I help startups and enterprises with event tracking and analytics, production machine learning and MLOps, LLM and RAG applications, A/B testing and experimentation, AI workflow automation, and data visualization — end to end, from instrumentation to production.

I'm based in Islamabad, Pakistan (PKT) and work fully remotely. That gives me solid working-hours overlap with both European and US time zones. Engagements are run async-first, so progress never blocks on a single daily call.

Yes — I work with clients worldwide across the US, Europe, and Asia, fully remotely.

With a free 45-minute discovery call to map your data stack, goals, and the fastest path to ROI. I then send a scoped proposal with deliverables, timeline, and transparent pricing. If it's a fit, we start with weekly check-ins and working software each sprint.

Most work is fixed-price against clearly scoped deliverables, so you know the cost up front. Time-and-materials is available for open-ended or exploratory work. Pricing depends on scope and complexity, which we nail down in the proposal — no retainer is required to start.

Every engagement ends with full documentation, team training, and a 30-day window of included support, so your team can own and run what we built confidently.

Yes. I target your current cloud (AWS, GCP) and tools rather than forcing a migration, using managed services where they save time and custom infrastructure only where it pays off.

Yes — I ground answers in retrieval, require citations, build evaluation harnesses that catch regressions before release, and add guardrails so features degrade gracefully instead of hallucinating. See the LLM / RAG service page for details.

Often yes. Common engagements include cleaning up a messy analytics setup, productionizing an existing model, or hardening a RAG prototype with evals and guardrails.
