Hi, my name is Oleksii, I am a developer for Apple platforms with 12 years of experience. Currently I maintain MacPaw/OpenAI GitHub repo. Ex MacPaw, ex Onix-Systems. Sometimes working on my pet project - Evenly. I’ve worked on a very large number of different projects, but my expertise lies in apps that do most work on the client side (I.e. without backend): The apps would work heavily with database and file system, either directly or through corresponding frameworks: Core Data, PhotoKit, GRDB etc. Such apps would usually require efficient utilization of CPU and memory, so I’ve mastered tools for that: Grand Central Dispatch, Combine, Swift Concurrency I like to organize the code in a way that makes sense. There are many best practices on how to do a better organization: SOLID, composition over inheritance, less coupling more cohesion, using design patterns etc. I know most of it and have an experience using them, so now I don’t just use complex stuff for the sake of it, but apply what’s needed where needed I am also a fan of keeping quality and performance in check, so I would use Crashlytics, Sentry, MetricsKit to log errors, collect metrics and keep an eye on crashes Not 100% of the time, but more and more I use TDD to do faster initial implementation through a short feedback loop, and also to be more sure that I don’t break anything during refactoring later I’ve also come across many very hard-to-debug issues in my career, so I had to become better at debugging. I like to use Instruments like Profiler to find inefficient CPU usage. I also usually prepare logging in advance so that when user has an issue and we can’t reproduce it locally, we could get as much information from them as we can without asking them 10 times. I enjoy automation, so when there is a chance, I would gladly write a script or use some tool or technique to not do it manually and save time. Below are some info about my precious employment. See Employment History on Upwork Profile for more details. First half of my career was in outsource company Onix-Systems, where I worked on a lot of very different projects, estimated pre-sales, and lead the whole iOS department of the company. During that time I also made my own startup of a simple loan recording app Evenly, which was my main playground to learn some development/product/marketing topics deeper that I could while working main job. Then I moved to MacPaw which is a product company, where I've worked for 6 years in a product team. There I learned industry standards and state of the art approaches to full-cycle development of a product, marketing, working in a focused team, development processes, infrastructure etc. There I worked on such apps: Gemini Photos (now CleanMyPhone), Gemini 2, Swoosh Video Editor.

NodeJS, NestJS, AWS, VueJS Web Developer For the past 16 years, I've been working in web engineering and polishing my skills, creating applications of different complexity. Currently, I'm mainly focused on full-stack JavaScript/TypeScript development with NestJS and VueJS. Most used databases: MySQL, Redis. Most familiar infrastructure: AWS Services. SCM of choice: GIT (including GitLab/GitHub) I have experience with serverless solutions, most commonly utilizing AWS Lambda for various background jobs and lightweight APIs. I usually use the "Serverless Framework" for these. I also have a good knowledge of PHP. While I'm not interested in active PHP development, if it is part of the system or something that needs to be converted to NodeJS, I'll be good with that. On the way, I learned many related technologies, skills, and concepts, such as Linux administration for servers and everyday desktop usage, understanding of networking, image manipulations with ImageMagick, Docker, CI/CD, etc. I'm always open to learning new things and happy to do it. My work is a kind of art for me, and I do everything possible to achieve beauty and efficiency in my creations.
