Evgeniy / OZ — Between sea & stars

I prefer to solve mathematically challenging tasks (I love applying math to real-world problems).

I combine best practices with years of experience to design clean, scalable application architectures that support collaboration and code reuse.

I have experience building CRM, ERP, and WMS software for large e-commerce businesses and small startups.

Rust: since 2015
Angular: since 2011
Ionic: since 2013
PHP: 2004 — 2016

Rust

Systems & services

I’ve enjoyed programming in Rust since 2015.

Most of my Rust experience is in web development — REST APIs, database connections, data analysis, and background task execution. I also have extensive experience with caching, mutexes, semaphores, preventing cache stampedes and race conditions, and managing resources with RAII.

One of my achievements is a REST API written entirely in Rust, serving multiple web and mobile applications, including a CRM, a task manager, mobile apps, and websites.

Angular

Interfaces & architecture

In Angular, I can write directives and components of any complexity — including interactive maps (Angular + D3.js), nested trees, SVG elements, and other fancy things.

I can build a modern, solid foundation for your Angular project using Nx and NgRx, applying the industry’s leading solutions for structuring and organizing folders and components.

I can improve your app’s performance by using the OnPush strategy, tuning ZoneJS flags, using requestAnimationFrame, reducing reflows, moving some modifications out of NgZone, and making other improvements.

I can build services and libraries based on best practices, using RxJS, declarative event-driven programming, and Reduce patterns.

Ionic

Beyond the browser

I have experience with Ionic and have created multiple mobile apps with this framework, including a sophisticated warehouse management system (WMS) with mobile apps for scanning, instructions, printing price stickers, moving items, and scheduling deliveries.

Technologies, apps, and services I have experience with:

Rust, TypeScript, JavaScript, PHP; Angular, Ionic, RxJS, NgRx, Nx, Karma, Protractor, Twitter Bootstrap; MySQL, PostgreSQL, Redis; Cloudflare, Mandrill, PayPal, Stripe, Nexmo; GAE, AWS: EC2, S3, Cloudfront, Pipeline, CodeCommit, RDS; Jira, YouTrack, Git, Travis CI; SOA, REST, SOLID...

As a contractor, I’ve worked with Vodafone (a device control system) and NTT & Sony (a custom payment system library for Spartacus CRM).

My favorite books are Clean Code and Patterns of Enterprise Application Architecture.

I like and respect SOLID principles.

Origin story / 2004It started with
a mobile phone.

My passion for programming started at school.

In 2004, I started earning money by making websites.

One of my first tools was an FTP editor — a tool for uploading, removing, and editing files (mostly PHP scripts). It was designed for use on a mobile phone (in 2004, not every Russian youngster had a computer, so “mobile-first” was more than a motto for us).

The most interesting part: I had just three hours of computer access to develop it. I wrote the rest of the code using the editor itself — yes, from a mobile phone.

This tool helped dozens of people create their first websites (or WAP sites).

It was challenging but extremely rewarding.

I can:

Design software architecture (I prefer the hexagonal architecture pattern);
Design database schemas and naming conventions;
Create Web apps (frontend, backend), mobile apps, CLI tools, daemons, and libraries;
Design and create RESTful APIs;
Integrate Stripe or other payment platforms into your app;
Provide consultations;
Optimize DB queries;

When hired:

I will not answer “it’s impossible” to feature requests;
My main motivation is money — while an employer pays me, I do the job;
I can share my opinion and warn about consequences, but I will not be confrontational — whoever pays the piper calls the tune;
I don’t work with rude or arrogant people (and money can’t fix it);
I will not unexpectedly disappear from a project (while alive);
Work-life balance matters — I work eight hours a day, no more. If a situation is critical, I’m available at any time, but it cannot happen every day.

I work remotely from Barcelona and can work in time zones from GMT-8 (PT) to GMT+0;

Feedback from
previous employers.

Evgeniy is an extremely competent Rust developer. He implemented everything correctly with little management needed - the first drafts were production ready, communication spectacular, estimates precise, and his level of enthusiasm for the Rust language and ecosystem boundless. I'd be glad to work with him again any time.

We recently completed an extended project (over 5 years and 9 months) with Evgeniy and are very pleased with his work and highly recommend him. The project expanded into many related projects and went well beyond its initial scope. As the need for different business tools took us in many different directions, Evgeniy was able to handle all of those pivots with great skill and determination.

He worked on everything from our initial PHP/Phalcon website to mobile app development, building a custom CRM and task management system, internal business operation tools, landing pages, white-label members-only websites and much more.

He is highly advanced in his abilities to solve business problems with web-based applications and to optimize those systems for high availability and performance.

His approach is full-stack as he can handle everything from server setup, security, front-end development (latest version in Angular), backend development (latest version in Rust), MySQL optimization, OOP coding, unit tests and system documentation.

Evgeniy is able to take project requirements, ask good questions, offer suggestions and deliver on whatever portion he is assigned. Working on our projects he also had to be very flexible and was able to change directions as needed.

Based on our experience, we consider him one of the top programmers on Upwork and highly recommend him if you need a programmer that can help turn your ideas into working business solutions.
