Front End Developer

UI online banking aplication for NatWest Group customers. The project involved architecture design of re-platforming from legacy .NET stack and a solution that allowed to use the same code base that has been split between 6 different NatWest brands in the build process as well as interaction with existing backend REST infrastructure serving mobile applications. After release it was a public facing SPA that is currently being used by millions of customers on a daily basis.

Re-platforming of a Big Data driven Profit&Loss web app for bank managers from AngularJS + Mocha / Karma + Protractor to ReactJS + Redux with Jest and Puppeteer. The application allows to generate financial analysis, profit&loss insights, forecasts, graphs, chars and financial reports.

Big Data based and developed with React / Redux / GraphQL e-commerce ecosystem application for business customers. The application allows to generate commercial analysis, product development insights, forecasts, graphs, chars and business reports.

The Telegraph's Newsroom Authoring web app for journalists and editors. The application allows to create, edit and manage news, articles and galleries that eventually appear at telegraph.co.uk

Big Data based and developed with AngularJS 1.5 components e-commerce / loyalty program application for business customers. The application allows to generate commercial analysis, product development forecasts, graphs, chars and business reports.

'Six degrees of separation' is the idea that all living things and everything else in the world are six or fewer steps away from each other so that a chain of 'a friend of a friend' statements can be made to connect any two people in a maximum of six steps. Based on that a new idea emerged within Financial Times to find out how noteworthy people are connected via news and features published by the company.

Every published FT article is being described with structured metatags - it creates a huge Big Data source for analysis. During my time at the FT I had a pleasure to design an architecture and develop an e2e NodeJS, ReactJS and D3 based application called 'Six Degrees' that was making use of this data source and was a direct instantiation of the idea.

The scope of the app was so called 'co-occurrence data': instances of two or more people being tagged in the same article. It wasn't clear what's the relationshop between people appearing in the same articles (do they have a positive, negative or neutral relationship), but as usual in the Big Data world, where amount of data is so significant, it was enough to create a high level of understanding of people's connections.

The migration from an old to new technology stack was a very challenging process for the back-end team I was working with during my time at Financial Times. The set of goals that they had to achieve was very complex and managing it was previously happening via... manager's spreadsheets. So even monitoring their progress by many other dependant teams wasn't an easy task.

I've been asked to design and develop two boards that have been displayed at several screens within the organisation and were giving live updates about the progress of the team.

FT Internal Tools: KPI Tracking & Parity Monitor were applications that I have created an architecture for and developed using ReactJS framework. Both solutions involved a full end-to-end production flow from development and repository updates through code reviews, tests, build process and continuous integration up to continuous deployments (using Webpack, Github, Heroku, CircleCI and Docker).

During my time at Financial Times, the back-end team was working very hard on a very complex process of transition from an old to a new version of their massive content API. On a daily basis the IT support team was receiving queries about differences in an availability of articles, images or other content assets. To better support those queries, I've been asked to create an internal tool that would be able to request those assets from different sources to quickly compare the results.

That was a high-level requirement of Content Comparator - an application that I had a privilege to fully design from technical perspective and develop using Angular2 framework. The solution that emerged involved a full end-to-end production flow from development and repository updates through code reviews, tests, build process and continuous integration up to continuous deployments (using Webpack, Github, Heroku, CircleCI and Docker).

As a Lead Front End developer I had a chance to create a FE architecture and to be involved in creation of a new version of Deutsche Telekom flagship online product: the CDB portal that aggregates data from several T-Online services.

During my time at Deutsche Telekom UK I was introducing and managing process of code quality management within the team (coding standards, design patterns, esLint, Karma / Mocha unit tests, Protractor E2E tests)

To make the development flow complete I have designed and implemented a Grunt task runner based solution to deliver a full release process from developer's local environment, through gated commits to repository and CI environment up to UAT/Prod environments.

Data allowance app for Deutsche Telekom UK (via EE) customers

At the time I was working at GMO UI Buildkit team and was focusing on responsive and performance solutions for high profile, high traffic eCommerce platform, which is one of Tesco's flagship products: the Tesco Direct.

After taking over a role of Javascript Team Lead I had a chance to introduce and manage process of code quality improvements within the team (coding standards, design patterns, jsLint, Jasmine unit tests, TDD).

Was also involved in architecture design and development of general front-end solutions for Tesco kiosks experience. At the time I've created a custom MV* API solution based on BackboneJS – built from scratch and tailored for Tesco eCommerce platform specifics.

Enabling Skype video calling experience on Outlook.com

It was the biggest project I was involved in during the awesome time I spent at Skype company. We were building a web app that allowed Skype users to communicate between different web platforms. After Skype acquisition by Microsoft, there were several ideas about how to enable Skype experience in Microsoft's flagship products. One of them at the time was Outlook.com.

The Skype web library we'd created did allow Microsoft email users to establish video calls between each other as well as between them and Skype users. Due to an additional possibility of linking accounts easily, the Skype users network has grown up rapidly.

Enabling Skype video calling experience on Bing.com search results.

As a member of Skype Web Experience team I was working on moving video calling from the OS application to the web. One of the first projects where we were able to see our SkyJS library in action was Skype Web Experience for Bing.com. At the search results page, the search engine users have been given a chance to immediately establish a connection with those who they were looking for - if there was a Skype id or a phone number in their contact details.

Once the wembleystadium.com website has been successfully rebuilt according to newest web standards and accessibility rules, I have been asked to prepare designs for subpages that have not been prepared during the main development process.

The task was actually quite challenging because I had to prepare the project not only according to existing website design, but to combine expectations of Marketing Department with the e-shop back-end engine from the third-party supplier.

After many years of successfull services provided by traditional Wembley store, now the time has come to conquer the e-market...

The FA Licensed Coaches' Club website provides to FA Licensed football coaches the latest methods, session plans, drills, CPD, videos, news and jobs.

The work on this project gave me a good experience and familiarisation with Orchard - a .NET-based CMS application, used also for the very first time by the company I worked for (The FA). The whole philosophy of building Orchard templates allowed me to create modules & components with front-end focused approach.

At the beginning of 2008 the management of Fitbug Ltd. made a strategic decision to create a completely new design of company's most crucial asset - the website.

In 2006 I have come to London to expand my front-end development skills and knowledge. I have started to work for company which is leader of healthy lifestyle / fitness market in UK.

These days in Fitbug I've worked on rebuilding their website's front-end code from version 2 to version 3, which was necessary because of their market success and services enlargement. I was really big job, which gave me experience I haven't got before - especially in cross-browser non-compatibility, css tricks and building the xhtml code in accordance to W3C standards.

At the beginning of 2008 the management of Fitbug Ltd. has decided to create completely new design of company's website. The back-end code should stay the same, but the front-end code had to be built from the beginning - this meant really exciting challenge and a lot of work for me... And this task has been accomplished with success as well - the actual Fitbug website www.fitbug.com has been built on front-end side by myself.
