Developing a block-chain project with price stable cryptocurrency (https://usdx.cash).Within the team we maintain principles of— short iterations, constant value delivery;— clean code, concise documentation;— test-driven development;— horizontal hierarchy.These principles helped us to build a streamlined and predictable development process always aimed on business and customer satisfaction, but preserving friendly and healthy relations within the team, driving their performance and creativity.Technologies/tools/approaches stack:— Java, Tomcat, Hibernate;— clean code, TDD;— agile, user stories;— Docker, Kubernetes, Google Cloud, Helm;— microservice architecture;— git-flow;— CI/CD;— ReactNative, TypeScript, Mobx;— BitShares, Hyperledger Fabric.We grew our product from MVP to fully-functional payment solution with over 60k customers (and counting). Lots of non-trivial challenges were solved, including:— designing sophisticated mathematical models and algorithms for smart-contracts;— refactoring monolith solution into scalable microservices;— tuning mobile wallet UI/UX according to community feedback;— setting up a fault-tolerant infrastructure;— refining DevOps and support processes;— application performance monitoring;— heuristics algorithms to detect and ban cheaters and spammers;— security risks mitigation;— integrations with crypto exchanges and payment gateways.

I started as an iOS developer, then was promoted to Lead iOS developer, then to Lead Architect and finally I become a CTO.During almost 3 years we developed a bunch of projects for logistic, fintech, education, BP management, etc. When I came at 2015 it was a several month old department, with couple of developers but without any infrastructure, process or standards. I started everything from the scratch: evaluated developers and cleared some space, built a team of professionals, including iOS devs, QA, PM, support, DevOps, frontend and backend engineers.With the team we— established clean code standards and practices;— introduced agile;— built reliable IT infrastructure;— created a trustful communication environment for geographically distributed teams.We mastered a lot of various tools, techniques and frameworks, including:— platforms: iOS, Android, Web;— arch.patterns: MVC, MVVM, VIPER, FLUX, DI, IoC;— unit testing: Expecta, JUnit, Mocha, Jest, OCMock;— logs, crashlogs: Crashlytics, Sentry, Stackdriver;— monitoring: Zabbix, Proteus;— backend: Tomcat, Strongloop, Swagger;— frontend: React.js, ReactNative, Cordova, Angular, MobX;— CI/CD: Gitlab CI, Teamcity, fastlane; — deployment: AWS, GCD, Docker, Kubernetes;— approaches: microservice architecture, declarative client-server contracts;— database: MySQL, Mongo, ElasticSearch.As a result we were able to successfully deliver products for:— a big financial corporation;— platform for logistics industry;— highly successful project for educational sphere;— platform for eco-energy integrator;— crowdsourcing platform.My responsibilities included, but was not limited to:— resource and project management;— collaboration with customers;— maintaining a communication and development standards, as well as team motivation.

I was offered a position of CTO in the really challenging project that stand on the edge of hardware and art.It started from a prototype for "Escape The Room" quest, a real-life adventure game that I build from the ground up.Using gained experience I was able to:— design a software and hardware architecture;— build experience in hardware development, enough to talk same language with hardware engineers;— form an awesome team;— develop a server side solution to manage quest logic.Then it come to actual work, in the team we— established way to use agile practices in hardware and art development (crazy, huh?);— built clear communication environment based on trust, friendliness, and mutual assistance between teams of engineers, artists, game and level designers, property-mans, fitters — everything to gain the most of the team creativity and performance;— introduced early releases;— developed UI to allow quest manager to control every bit of quest logic and player experience, to increase players satisfaction;— participated in numerous brainstorm meetings with game designers to help them map their imagination to the rules of the physical world.From the technical perspective we — invented a way to make unit testing of hardware endpoints on development and deployment stages;— maintained code standards and code review practices throughout all stages of development process;— integrated all-new method for remote firmware upgrade of game devices, tremendously improving deployment and maintenance processes;— introduced object oriented approach for microcontroller code, improving developers efficiency;— developed sound control software.A lot of things developed during this project was a know-how for Escape The Room world. System allowed for rapid game logic updates, full control of game flow, emergency protocols to satisfy players even if some hardware parts become inoperable. Even competitors noted our technical design advantages.

Here I began as a Unity3d developer, having no experience with this SDK. Was able to built good skills in Unity3d game development from the ground up. Then I was promoted to the role of Lead Developer, then to the CTO.What I did there:— developed 3D tycoon fantasy game, introducing MVVM architectural approach, IoC and Command design patterns, this allowed to dramatically simplify code structure, parallelize team work, gain good test coverage and improve overall development process quality;— prototyped several other games;— built CI/CD pipeline from the scratch, using TeamCity;— recruited and coached several new developers;— managed to find and evaluate some outsource teams, to parallelize development and achieve business goals;— built communication framework with outsource teams (CI/CD pipelines, documentation practices, infrastructure automation);— built and maintained development process standards (code style guidelines, architectural practices).Technology stack:— Unity3d;— StrangeIoC, Daikon Forge.
