Design of splitting REST monolith to microservices, the implementation and support. Thus decreased peak server load up to 37% and led to cost reduce up to 21%.
At this point I'm interesting in both tech and management branches, so need to try a bit more diving into each, one by one.

I was working in the following domains:

1. Game dev related.
Responsibility area: detailing requirements from the abstract "hey we need extend feature A, so our new partner could use it" to the ones which will say how, in which manner and via which clear interface it'd be working etc.
Then designing, implementing, covering with tests, fixing by need.

2. Food tech.
I was doing: onboarding new clients (adjusting our adapters to their old fashioned data structure like xml), was onboarding new team members, so it was kinda team lead experience xD, was involved in design and was  fixing bugs indeed.

3. Fintech, the vehicle leasing service with ability to make an offer to the dealer, to haggle/bargain.
Was fixing bugs, extending old features, was taking a part in splitting monolith to microservices, was implementing cars search and notification service.

Techs and tools: Node.js, Express, Koa, Nest.js PostgreSQL, Sequelize, Knex, vanila JavaScript, a bit React, HTML and CSS.
AWS: SQS, SNS, Lambda, EC2, ECS, S3, API Gateway, development and deployment.
1. The Team where I eager to work: smart people with extremely high tech level (both in knowledges and hands-on experience), which would help by need. In this team I'd like have an ability of growth. Personality matters, needles to say.
So far I was lucky to meet this kind of teams.

2. The Project that serves for humanity with good deeds and where I could implement all new tech stuff and learn new.

3. The Stakeholder/Employer that values each employee of his company as a crucial part of the succes. Perfect if the employer's managers know about employee motivation tactics and implement 'em in live.

At university, I worked on a large number of interesting projects, most of them web applications:
Microservice Constructor
My bachelor's thesis project, created to make the development of microservice-based web apps easier. It consists of two parts: 
-	Console app (Typescript), which accepts configuration file and allows generating a significant part of web app code.
-	Web app (frontend with Angular, backend with NestJs, deployed with GitHub Actions to Heroku) which allows producing that config file with UI.
Library Website
University group project, where I was responsible for all front-end on React and parts of back-end on Koa which included some basic CRUDs and custom search with the support of logical operators.
Pichupido
University group project, which is API (Koa) for web-app created to allow restaurants to manage online menu easily. Here I was responsible for most of the business logic and for testing with Jest.
Image-converter
University group project, console app (Typescript), which allows converting image from one format to another, and allows rendering obj-files using ray tracing. I was responsible for general architecture, ppm and jpeg formats, and optimization of basic ray tracing with KD-tree and for adding features such as rendering scenes with multiple objects and light sources, rendering spheres, disks, cubes and planes and not only polygons, rendering reflective surfaces.
