Whether you're seeking expertise in data analysis or looking for a leader to bring groundbreaking projects to fruition, I bring a wealth of experience and a track record of success to every endeavor. IMPORTANT! Before contacting me ask yourself: 1. Do I have the necessary data for this project? (I'd very rarely be able to provide data for your project.) 2. Is the data suitably prepared for a machine learning project? (If not, there will necessarily be a stage for EDA and ETL which normally takes some time.) 3. Is it really feasible given the current machine learning state-of-art? (Some ideas are simply either too far from reality or demand a large amount of investment for becoming real.) 4. Do I have enough budget to afford this project? (Be realistic about the project you're proposing.) My mission is to provide you with a model that can meet your expectations, but the expectations should be realistic - and that's why I have 100% of success in my projects!
