Apache Spark committer and Databricks Beacon. Other than that, just a dog on the Internet. I would love to tell you more, but then, of course, I'd have to erase your memory. **Note** I am not taking any new commercial requests at the moment, however I am happy to volunteer my services to non-profit or research institutions https://twitter.com/\_\_zero323\_\_/status/1243210621589610499 https://zero323.net/ **PGP** A30CEF0C31A501EC / https://keybase.io/zero323 **Fees** Fee for short-term requests from business clients is non-negotiable with exception to cases described below. If you are looking for long-term help please consider posting an offer on Arc, which among other benefits, provides a favorable platform fee structure. If you represent a non-profit organization, academic entity or you are an individual interested in long-term mentorship please contact me directly so we can discuss your requirements and eventual discount. If I respond to your requests or add request notes, it usually means that I accept suggested rate and already applied discount. Please check the fee visible to you in the chat window to confirm that. **Guarantees** Due to the nature of live sessions (lack of formal specification, possible technical and communication issues), a satisfying resolution of the problem is not always possible, therefore I offer a 100% satisfaction guarantee. If for some reason you are not satisfied with an outcome of the particular session please provide me with the feedback and request a refund before we disconnect and I will issue it promptly after the session is finished. **Non-Disclosure Agreements** TL;DR I won't sign your NDA, and if you start a conversation by sending one, I won't respond. To not to reiterate things which have been said more eloquently multiple times please take a look at the Entrepreneurs vs. Freelancers vs. VCs section of the Codementor Essential Guide to NDAs (https://tinyurl.com/entrepreneurs-vs-freelancers) for the explanation. **Academic integrity** Please don't ask me to be involved in activities which would violate your academic integrity, like completing graded assignments, writing research papers or thesis. Also please note that requests like this are explicitly forbidden by the Codementor Terms of Service (https://www.codementor.io/terms). I am happy to help you with projects explicitly allowing external collaboration (as long as it can be confirmed using publicly available syllabus of comparable source), reviews and overall mentorship and guidance. I am also a huge enthusiast for lifelong learning. Don't hesitate to contact me if you're looking for support and study help (in boundaries of applicable Honor Code) when taking publicly available online courses in topics related to general programming, machine learning, and computational biology.

**Full-stack software engineer.** - Backend specialist for 5 years at S&P and Banqsoft. - Mobile specialist for 7 years with Diversido, Noble Muffins and other clients. - Professional experience with React, TypeScript, C++ and Java. I got my start when I took over IT at a horse trailer dealership to gather money to move to Europe. At S&P, I took our team's first two microservices from zero to production. I later served as scrum master, and was given a technical excellence award for my work in SQL optimization. As a game developer, my Turbo Slicer product has been featured repeatedly by the Unity Asset Store. I wrote a finite element analysis kit for PlayWay S.A. to manage building collapse for the games Construction Machines 2016, Demolish & Build 2017 and Demolish & Build 2018. As a mentor I will solve your problem and explain it with patience. My favorite highlights from my time here: * Helped an experienced engineer build a Gtk-based UI for an industrial control unit. * Helped an entrepreneur deliver a Unity-based VR demo to customers and investors. * Debugged problems of concurrency, thread safety and asynchronous IO in iOS apps. * Lead a student through correct authoring of a filesystem driver. I check Codementor daily. Write me and let's get something done!
