  • Created desktop clients using Electron and React for all OS systems. Electron apps can elevate to admin mode to install an OS service. Developed a custom auto-update mechanism that runs tests on that OS/device to ensure the app will not be broken.

  • Experienced with packaging Node.js applications into one executable, and launching them as OS services.

  • Created highly scalable back-end application with Node.js using TypeScript with MongoDB and Redis.

  • The web app uses WebSocket for messaging and to support data-streams to draw SSH terminals or VNC/RDP desktops directly in the browser in Canvas without using any browser extensions.

  • Architected a system to manage secure tunnels using Docker containers and dynamically managing the containers once tunnels are opened or closed. The system is written fully in Python.

  • Created a custom zero downtime, authentication, and more in reverse-proxy engine fully with Node.js.

  • Helped developers to scale the system on resource-limited devices like routers and chips, wifi, and ethernet enabled devices, like Espressif's esp32 chips.

  • Developed a system in Node.js that connects to the back end, listens to MQTT messages from the server, and can open SSH tunnels which are also fully written with Node.js, download code packages, execute scripts as custom OS processes on the device.

Portfolio

Strat Align

An SPA to enable users to create custom data visualizations based on Cube database. Later, users can share these visualizations within the team and have the ability to comment to a particular chart. Tech stack: Ext.js 5, Rave (IBM visualization engine), Cognos TM1, Odata v4.

Tunnelin

Tunnelin is a general purpose service, allowing you to access and control all your devices (from Windows/Linux/macOS to small IoT devices) independent from the network topology (devices behind NAT, firewalls). We support ssh (RDP, VNC, http) tunnels to your device. For IoT devices, we support real-time messaging between devices and central dashboard (using MQTT protocol), thus allowing you to send and receive data to/from devices. Technologies: React, Electron, Node.js, TypeScript, Docker, MongoDB, MQTT, Redis, ssh, Python, Lua, C, Ethernet and/or WiFi enabled chips (i.e.ESP8266, ESP32 etc.).

Align Business Application

Created a platform that acts as an SPA, but its role is to be a container for other applications and/or UI components designed for a specific case and solve integration issues, as it is not guaranteed that applications/UI components are written in the same technology stack. The platform also provides a data abstraction layer and has a lot of modules to manage (CRUD, filters, etc.), analyze, and visualize that data in various ways. Tech stack: Ext.js 4, AngularJS (1 and 2), TypeScript, React.js, D3.js, MS SQL, Elasticsearch, .NET, Python, and more A lot of applications from Align company are using this platform at some level.

Country Office Monitoring and Evaluation Tool

The project is to create an internal application used in WFP UN. Tech stack: PHP, JavaScript, HTML, CSS, Ext.js, Zend Framework, Doctrine, Jira, GitHub, GreenHopper, Jenkins, PHPUnit, JMeter, iReport, MySQL, Linux. Also, the system was integrated with existing technologies (SAP/WINGS via a SOAP web service, Active Directory).
