Annotely is easy to use web based screenshot annotation and markup tool. Works on any browser and any device - mobile or desktop. Privacy focused application where are image manipulation is done on client side.

A real side project started in early 2010 🥹. A private battleground to learn new technologies and practice product development. Annotely currently has a steady growing number of users.

Fabristic was an online B2C venture where users could create t-shirts, backpacks, pillows from their Instagram posts.
All instagram photos were imported automatically to present user products.
I did web frontend application, iOS application, backend and all integrations. In a nutshell - all was done wrong.

Led a team in creating a web-based order creation and tracking application for a concierge platform. Oversaw team building and served as the lead React engineer. As a React lead created several prototypes during the project's initial phase. Designed application architecture, selected tools, and managed integrations with third-party applications like freshdesk.com and tookanapp.com using Python and AWS.

Online B2C photobook printing company where I was tasked with a challenge of creating a client application, custom desktop publishing (DTP) solution and end-to-end architecture design (i.e. data exchange and storage formats). As a solution architect I was responsible for building Adobe Flex client application and migrating it to React. I was a lead engineer responsible for implementing all crucial React components.
Solution I created is currently handling tens of thousands of orders with fail rate far less than one percent.  Key challenges I was facing were - first, high memory consumption issues while working with large numbers of user photos (with average size over 2MB) multiple low level image manipulations and uploads. Secondly a number of security threats while processing user provided files. And lastly, rendering performance issues we faced when rendering content interactively modified by users. I was also responsible for creating data flow architecture as well as API specification for both company owned client application and external printing facilities. As a technical team leader I was coordinating the work of 3 other software developers. I’ve created a multi platform React application to be run on desktop and mobile devices with clear UI and BL separation.

Due to job force cuts my position was terminated based on short employment history (ref. blog.kraken.com/post/16442/bus…) 🤷🏻‍♂️

Member of Adobe Prototyping Team (internal R&D). I was involved in multiple of the internal projects working as a full stack engineer focusing on providing complete solution for product prototyping needs. Working with React, React Spectrum UI, web components and iOS Swift. I've worked closely with stakeholders gathering requirements and building testable prototypes. As a full stack engineer I was also involved in designing APIs and backend solutions for prototypes I was involved in. APIs were mostly created with TypeScript and Node.js leveraging integrations with internal systems and deployed using Docker on AWS and later on proprietary cloud platform based on Kubernetes and Docker.
