Shrey Agarwal

**Experienced, efficient, flexible, friendly, no charge if I can't help!** **Proven technical interviewing tutor** **Specialize in backend (C#,C++,Java,etc) coding and Azure** I have been a software engineer for the past 12 years at Microsoft, and have been solving problems for much longer than that. I am fast and efficient and will be honest about my expertise and timelines. I have an unbounded passion for anything technology, rising from an insatiable curiosity to learn more. In the plethora of technologies or fields that I already have knowledge of, I will be able to help right away. But rest assured that with me, you don't need to worry about knowledge till date. If I encounter a problem outside of my expertise, I would just jump in to researching everything about it, find pros and cons for all solutions and then helping out with the best one. Note - If pricing is an issue, ping me! We can work something out! :)

Willem Van Onsem

Developer by day, programmer by night. I obtained a master of science in civil engineering (computer science) and participated - together with several teams - in programming contests and hackathlons. I answer questions on StackOverflow on a daily basis and wrote courses on Artificial Intelligence and Digital Electronics. I am mainly interested in Haskell, Python, and Prolog. I worked as a researcher in the field of hyperheuristics (artificial intelligence), a teaching assistant in computer science and as a data scientist and technical lead developer in an AI startup. During my spare time I developed small (and larger) projects to help with daily routine. For me, a computer should aim to automate everything that is boring, such that one can pay more attention to what is interesting in life. After each session, I aim to write a document (usually within one week) that describes what we discussed. The public GPG key can be found here: https://pgp.mit.edu/pks/lookup?op=vindex&search=0x6A148004A6024E2B Usually available between 17:30 - 21:30 UTC (Monday to Friday) and 9:30 - 21:30 UTC (weekend).
