Web developer (Rust, Angular, TypeScript, Ionic)

Rust - since 2015, Angular, Ionic - since 2011, Web dev - since 2004. I have experience with: Rust, TypeScript, JavaScript; Angular, Iron, Ionic; RxJS, NgRx, Jest, Twitter Bootstrap, Angular Material... Databases: MySQL, Redis, PostgreSQL, Cassandra, MongoDB, CouchDB. I prefer to solve mathematically-challenging tasks (love to apply math to solve real-world issues). I follow best practices and my years of experience to design apps architecture clean, scalable, and easy for collaboration & code reuse. Have experience in writing CRM, ERP, and WMS for big e-commerce and small startups. In Angular, I can write directives (components) of any level of complexity - including interactive maps (Angular+D3.js), nested trees, SVG elements, and other fancy things. I can build a modern and solid foundation for your Angular project using Nx and NgRx, applying a collection of the industry’s leading solutions for the folders/components structure and organization. I can improve the performance of your app as much as possible, by using the OnPush strategy, tuning ZoneJS flags, using requestAnimationFrame, reducing reflows, and moving some modifications out of NgZone, and many other improvements. I can build best-practices-driven services and libraries, using RxJS, declarative event-driven programming, and Reduce patterns. I have experience with Ionic, I've created multiple mobile apps with this framework, including sophisticated WMS (Warehouse Management System), consisting of mobile apps (scanning, instructions, price stickers printing, items movement, delivery scheduling). I'm enjoying Rust programming since 2015. Most of my experience in Rust is related to webdev - REST API, DB connections, data analysis, and tasks background execution. Have a lot of experience with caching (also with mutexes, semaphores, preventing dog-pile and race condition effects, and RAII control of resources). One of my achievements is 100% Rust REST API, serving multiple Web and mobile apps (CRM, Task Manager, mobile apps, websites). As a contractor, I've been working with Vodafone (devices control system), NTT & Sony (Spartacus CRM custom payment system as a library). My favorite books are Clean code, and Patterns of Enterprise Application Architecture. I like and respect SOLID principles.

"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."
