About

Autumn discount!!

I have received several messages asking me to consider offering discounts lately. In light of this, I have decided to offer an attractive 20% discount in all my plans (OBS: the discount has been already applied to the published prices) until the 15th of November. If you start your mentorship during this time, the discounted price will remain the same after the 15th of November, it will not increase. These prices can be combined with further discounts for quarter billing for a whooping extra 10%-15%-20% on top of the already applied 20% discount depending on the plan you choose!

I am multilingual Chief Consultant/Engineer in the areas of Data Science, ML-Data and Software Engineering with over 14 years of experience in data science, data analytics, software engineering, artificial intelligence and data mining. I have mentored dozens of people from fresh beginners to experienced professionals, to C-level executives. I hold a Ph.D in systems engineering and computational game theory.

I have also produced multiple scientific publications and presentations where I have dissemitated my work in several international conferences. At the moment, I am working at Atea AS (One of the largest tech services suppliers in Europe), where I lead and take part in many projects that aim to strengthen and solidify Atea value creation proposal to its clients, both in the public and private sectors.

David has been a great mentor for me for a while now. He listens to my problems and provides invaluable support and direction. I am very grateful to be working with him towards my career goals. I strongly recommend David for someone who is looking for a reliable, passionate mentor.

Jacob

David has been excellent in providing support and feedback in the project I developed to help me transition into data science which would have been difficult for me to do solo. He has also been invaluable in providing feedback on my resume, job search strategy, long-term career direction and any concerns I have regarding my current work. David is flexible and easy to get along with and I look forward to each time we have a call.

Jacob

Working with David has been great. He has a deep knowledge of machine learning which has been invaluable in both developing my machine learning knowledge from scratch and providing guidance on the project that I am currently working on. Despite having significant time differences, David has always been prompt answering any questions I have and bouncing ideas off of.

Jacob

Working with David thus far has been excellent. He has provided materials and tasks that have enabled me to get quickly up to speed with the foundations of machine learning providing a sufficient level of challenge with each task. Additionally he is very response and proactive with any questions that I have. I look forward to what the future holds.

I've been mentored by David for 20 months and it's been amazing. He's one of those people who's super friendly, patient and understanding, very intellectual but also with high EQ. Just an easy going good person. David knows so much about AI and stays on top of everything new. He's really quick at figuring out what's actually helpful and what's not. And honestly, his knowledge goes way beyond tech, he knows about health, food, sports, and all kinds of random stuff. What means the most to me is that he truly gets how I work on projects. I can be stubborn, and I easily get uncertain when someone doesn't give me time to properly explain myself. With David, I don't have that problem. He understands, trusts that the results will be worth it, and also knows when to challenge me, which helps me grow. David has been there for me in bad times too. He encouraged me to try combat sports and now I've lost 20kg and absolutely love it. It's so easy to talk about difficult things with David, whether it's how the mentorship is going or personal stuff I'm dealing with. He's always honest and sincere. He has this way of saying things that sound simple and logical but they help me really think things through and figure out what to do. Sometimes almost like the perfect rubber duck. David is truly outstanding and I'm grateful for his mentorship.

I've been working with David as my mentor for almost a year and a half, and he's been outstanding. David handles every situation with ease and truly understands how to help put things in perspective, whether it's about work or personal matters. He's someone I trust completely. What makes him a great mentor is his openness to discuss how our mentorship is going. Whenever I want to talk about our progress or make changes, he's always willing to work through it together. I highly recommend David to anyone looking for a professional, trustworthy mentor who genuinely cares about helping you grow.

David has been a great mentor, guiding me through the start of my freelance career and helping me work with a tech stack that includes Matillion ETL and Snowflake. He has also been a big help with my startup, Hylia.io, which is building a simple, multi-platform dashboard app that works as a virtual lifecoach and mentor, using gamification to keep users motivated. We meet twice a week, and those sessions are always fun. David has a good sense of humour and knows how to make me feel comfortable. His IT knowledge is impressive, and he always points me in the right direction and keeps me motivated. I'm really excited about adding AI and LLM features to my app. David knows a lot about these topics, as well as data engineering, which will help us build the right features. His advice is invaluable, and I couldn't ask for a better mentor.

Enri

David is an excellent mentor. He listens attentively, genuinely cares, and puts your mind at ease. He’s skilled at breaking down complex problems and communicates clearly and effectively. His ability to convey a lot with few words is especially impressive. David maintains a personal touch, adapts his approach to individual needs, and shows a strong appreciation for diversity. He has guided me through my questions about Snowflake, Data Engineering, and DataOps, providing clear explanations every step of the way. Additionally, David is committed to helping me achieve my personal goals and even suggests contributing to writing my online e-book about Data Engineering. I’m looking forward to many more sessions with David as my mentor. I have full trust that the outcomes will be successful.

Enri

I really recommend David. He is an outstanding mentor and an experienced professional who is key to my ongoing move into IT. He gives me clear, smart advice and a step-by-step plan. Drawing on his deep knowledge and real-world background, he is helping me build a strong foundation and see the bigger picture of the industry. His expertise in areas like Data Science and Software Engineering is crucial for preparing me for real-world jobs. This is helping me build confidence during this important change. Anyone who wants to start or move forward in IT should try to work with him.
