Hire · Machine Learning Engineer

Hire a machine learning engineer focused on models that earn their keep

Models that are measured, monitored and cheap enough to run. My ensemble fraud classifier reached 94% accuracy over 50,000+ ads, and INT8 quantization cut one production model’s inference cost by 60% without retraining.

Why clients choose me as their machine learning engineer

  • ExperienceSenior, and proven in production6+ years, 17 shipped products and 6 P@SHA ICT Awards. Co-Founder & CTO, leading 25+ engineers, and still writing the critical code myself.
  • ValueSenior expertise at a fraction of US/UK ratesI work remotely from Islamabad, so you pay well below US and UK senior market rates for the same depth, with working-hour overlap for the UAE, UK, EU and US East Coast.
  • Low riskFixed-price prototype firstA free call, then a working prototype on your real data in about two weeks at a fixed price. You see results before any larger commitment.

What I build

  • 01Classification and NLPEnsembles of LSTM, SVM, Doc2Vec and TF-IDF models served behind real-time scoring APIs.
  • 02Movement and sensor MLKinematics models for gait and movement analysis at 92%+ classification accuracy.
  • 03Model optimisationQuantization and ONNX to cut latency and cloud spend without losing accuracy.
  • 04MLOpsVersioning, evaluation gates and monitoring so models do not quietly degrade.

Frequently asked questions

Should we hire a full-time ML engineer or a consultant?

A consultant for proving feasibility and shipping the first production model; a full-time ML engineer once models are the product and need daily iteration. The full comparison is in my AI consultant vs ML engineer article.

How much training data do we need?

Often less than you think. Modern models fine-tune well on hundreds of labelled examples, and the audit includes a data assessment before you commit.

How much does it cost to hire you as a machine learning engineer?

Every project is scoped on a free 30-minute call. Because I work remotely from Islamabad, you get senior, award-winning experience at rates well below US and UK senior market rates, and the prototype phase is quoted at a fixed price so your risk is capped.

Do you work with clients in the US, UK and UAE?

Yes. I have shipped for clients in UAE, UK, Australia and Pakistan, and work remotely with overlap for UAE, UK, EU and US East Coast hours.

Do you write the code yourself?

Yes. I architect the system and write the critical code myself. For larger builds I also lead engineers from my team at Quickgen Technologies, where I am Co-Founder & CTO.
