Superb C++, Haskell, Scala, FP, and OO design chops. Expert at designing compilers, type systems, frameworks, and embedded programming languages. Strong background in pure mathematics, computer science, functional programming, and category theory.
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.

Software Developer. Interests: Machine Learning, BigData, Data Science, Cloud Computing. Passionate about thinking how to solve problems. Trying to give my extra-mile in every opportunity.
# š Hi, Iām DamiĆ”n **Senior Software Engineer** with 10+ years turning ideas into _real, working code_ ā using **Kotlin**, **Java**, **Python**, **Haskell**, **JavaScript**, and **SQL**. --- ### š But hereās what really matters: I know how overwhelming programming can feel ā and Iām *really* good at making it make sense. Whether you're: - A **beginner** who thinks `if` statements are witchcraft, - In **university or bootcamp** and your code feels like a tragic love story, - Or a **pro** getting roasted by a bug that mocks your debugger ā **Iām here to help.** --- ## š§ How I Can Help ### **š Starting from zero?** - Learn **Python, Java, Kotlin, or Haskell** ā no overwhelm, no nonsense. - Understand **core concepts**: variables, loops, functions ā *and why they matter*. - Build **real projects**, not just toy examples. - Stop copy-pasting code you donāt understand ā Iāll help you _actually get it_. --- ### **š In school or bootcamp?** - Tackle **assignments** with clear explanations ā not just magic answers. - Design class hierarchies that *actually make sense*. - Debug weird, soul-crushing errors. - Start **thinking like a developer**, not just surviving syntax. --- ### **š¼ Already coding professionally?** - Write **meaningful tests** (JUnit, Mockito, pytest ā no excuses). - Migrate from **Java ā Kotlin** or **OOP ā FP** ā _without the pain_. - Work confidently with **Spring Boot, GraphQL, PostgreSQL, MySQL**. - Refactor legacy code for **clarity, speed, and sanity**. - Finally grasp **functional programming** ā yes, *even monads* (no PhD needed). --- ## šÆ My Teaching Style - **No ego, no jargon** ā Ask anything. Iāll meet you where you are. - **"Why" over "what"** ā Iāll help you _understand_, not just repeat. - **Adaptable & fun** ā If cat memes help you learn, Iāll bring the cats. š± --- ## ā Bottom line? Whether youāre stuck, starting out, or leveling up ā **weāll make progress, one clear concept at a time.**
Over the last 20 years, I have mentored hundreds of students, especially in Universities, to succeed in their endeavors. I hold the most successful youtube channel in Greece, with 1000s of videos about programming, computer math, algorithms, AI, etc. I really hope to work with you to overcome every hardship, in your efforts for your degree!
Experienced full-stack software development engineer, with expertise in the Fintech and Blockchain space. My strongest skills include JavaScript, Python, Kotlin, Solidity, and AWS I have experience leading engineering teams in an Agile setting, mentoring junior engineers, and guiding the team to reach (and exceed!) its goals.
I have over 5 years of professional tutoring experience (and 1000+ positive reviews on Chegg tutors before they closed). I have worked with students of all levels of experience, from high school to grad school. I'm an expert on C, C++, Python, Java, functional programming languages such as OCaml, Haskell, F#, Prolog, Scheme/Lisp/Racket, etc. I can help with CS topics such as algorithms and data structures, Computer Graphics, Cryptography, Compilers, Programming Paradigms, CS theory (Finite Automata, Regular Expressions, Context Free Grammars, Turing Machines, NP completeness, etc.). I'm also happy to help with other math, such as Calculus, Discrete math, Statistics, Number Theory. If you want help with something other than what I've listed above I can usually debug anything, but I might be learning the material along with you.
Personally I am passionate about programming languages in general, enjoying clear understanding about the way they work. I can help you to learn programming languages, including unconventional ones, like Lisp, Erlang, Prolog, Haskell or Scheme. I also can help you with academic topics such as Lambda Calculus, Finite Automata (Finite State Machine), Push-Down Automata, Finite State Transducers and others. I enjoy explaining complicated things in a simple way. My past production experience mostly comprises from three things: - backend development with Ruby on Rails on various small and average-size projects - work on Flussonic video streaming server at Erlyvideo company using Erlang - frontend development using React, JavaScript and also a wide range of other languages and technologies.
IMPORTANT: If you want to contact me, and your timezone is significantly different, feel free to just open a session request during my timezone evenings (after 8pm till midnight). I've noticed that figuring out the request details via chat is extremely cumbersome. I'm a professional developer working on Application Performance Management in Dynatrace; currently stationed in Gdynia, Poland. I've done a number of jobs in the past, including Graphics Driver development at Intel, Game Development at Huuuge Games and other, potentially unrelated things. I've started programming wanting to be a game developer, so there's a huge chance I can help you with your C++ game project. I also know my ways around the low-level parts of C and C++. Right now my main focus at work is Node.js, so if you have some questions about that, ask away. I also did a fair share of weird front-end experiments, so Three.js, WebGL and stuff like WebWorkers don't scare me. And finally, if you need some tips about Haskell or functional programming in general, that's my personal hobby area. In general, don't hesitate to ask, as I always try to get the feeling for your problem so that we both end up satisfied!
I am an experienced web and mobile application developer with more than 4 years experience with client projects. I have participated in developing quality grade software for varying range of clients. I have keen interest in problem solving and software debugging. I also managed a software development team to deliver client software for a few projects. I am a lover of good code and standard software development practices (TDD, SOLID, etc).
