As I shifted into a Principal Engineering role, I took even further on the responsibility of scaling up the company’s Restaurant Web platform. The Monorepo (home of the restaurant platform micro-frontend apps) started as a single place to colocate our team’s micro-apps (around 5 apps in the beginning), but then grew under my stewardship to support more than 30 individual apps owned and developed by 7 different web engineering teams across 5 different timezones.I also revamped the deployment pipeline in TeamCity by parallelizing the processes and keeping the build times low as the number of apps kept growing.At the same time, I started having more conversations with other Restaurant FE teams (then expanded those conversations to cover the Diner side of the company as well) about unifying the design language and putting together a single Design System for the entire OpenTable organization. This was a massive effort to bring together all the frontend teams and figure out a common foundation that would work for all, and which would help us speak the same language in terms of Design and UI Architecture. I introduced new design system concepts (like semantic design tokens) and started to write guidelines and documentation that would later act as a single source of truth for all the UI decisions.

I took part in the expansion of the Restaurant Web platform from a Restaurant-only solution to Groups of restaurants, developing the initial Group Onboarding and Restaurant Activation features.Also part of that initiative was the introduction (and then further adoption) of a completely new User Permissioning system that takes into account the new groups and subgroups hierarchies, which slowly replaced the per-restaurant user access management system that existed previously. I also refactored the User Accounts section of the product to allow creating and managing user profiles as part of a group hierarchy.I started being in charge of leading a small group of engineers to shift our Restaurant Acquisition funnel from a sales-driven process to an online self-serve Onboarding experience. This allowed restaurants to be onboarded on our platform in as less as 30 minutes, down from 30 days or more through a sales representative. (Later on, under a different ownership of this feature, that number went even further down to an almost instant activation!)After the Onboarding feature, roughly the same team under my leadership was in charge of building an in-house solution for our global payments system on the Restaurant platform. The feature was slowly released across markets, starting with US, then expanding in North and South America, Europe, then finally Asia and Oceania. The feature was then handed over to our internal Billing team for maintenance, our team remaining available for ongoing support.During all this time I also started contributing to the internal React Components library, implementing and evangelizing best practices, better componentization, and kicking off some initial ideas and discussions around Design Systems. I also started maintaining the Restaurant Web platform on top of which most restaurant web teams build their product features. I slowly inherited the ownership of the critical tasks required for the maintenance and scalability of the platform.

Snipit - easily save and organize code snippets in the cloud; share and collaborate with team members.https://snipit.ioSnipit is a project born out of necessity. As developers, we always need to learn new things, techniques or technologies. And most of the time we are doing that, we spend a huge amount of time searching the web for pieces of code, commands, algorithms or answers to different problems that are new to us. We can always bookmark stuff, but SnipIt helps you by getting right to the point of it: tag, save and categorize snippets so you can easily find them later.Technologies used:- backend API written with ExpressJS- authentication provided by Passport- data storage with MySQL and cached with Redis- ssl connection through an Nginx proxy- React front-end using a Redux architecture

As part of the KAYAK Trips team, I was the primary engineer in charge of the entire Trips product redesign. Working very closely with Design and Product, I was responsible for translating product requirements and designs into technical tasks, breaking down the work into smaller achievable chunks, and estimating the required effort for each deliverable milestone.We progressively switched to a React-based components library and migrated our legacy jQuery-based UI to a React/Redux stack. During this redesign effort, I was also in charge of creating and maintaining our core UI React components.For our team growth efforts, I was also part of the initial and final stages of the recruiting process for frontend engineers for our React stack. I was in charge of conducting preliminary technical interviews and assessing the performance of the candidates, and I played a key role in the final decision-making stages of the interview process.Responsibilities:- Complete refactor of the Trips code base from HTML+jQuery to a React/Redux stack.- Define technical requirements and make sure deliverables are completed in a timely fashion.- Scale the React stack to work outside of the Trips vertical.- Design, develop and maintain the ever-growing React components library.- Evangelize the adoption of the new tech stack, teach and coach other engineering peers.

- I was part of the AMOMA.com website team and we were in charge of developing new features for our high traffic, internationalised web application. I worked as a Senior Full Stack Developer in an agile environment (using SCRUM methodologies).- The website is written in PHP, on top of Yii framework.- We used backend web services to fetch live data from the other applications; the data is transferred in XML format.- I wrote code in a modular way, usually following design patterns and best practices to ensure the long-term scalability of the application.- I wrote unit and functional tests to always ensure that my code worked as expected.- I also wrote the documentation, both technical (code) and non-technical (wiki).

website: http://duxtravel.roWorking as a Freelancer for the travel agency Dux Travel, my main responsibility was to redesign the whole website and to keep it fresh and in pace with modern technologies and user demand.Technologies used:- The website is built on top of a custom Twitter Boostrap css build, with a custom responsive layout based on cards (boxes) that can fit nicely on basically any screen size.- The layout is fully responsive and uses modern CSS styles and SVG graphics whenever possible.- The entire JavaScript is written in ES6 and it's split into modules that are finally compiled into a bundle (one for each page type) with Babel and Browserify.- Some of the components (the homepage quick search etc) are based on ReactJS.- The backend is a custom web shop framework written on top of Yii framework (PHP and MySQL).

Full Stack Web Developer:- I worked in one of the development teams inside the website department, according to the project managers specifications and always within a tight deadline. We used the SCRUM methodologies to work in weekly sprints.- We always delivered new features that were compliant with our high traffic and high availability website.- I used both front-end and backend best practices and design patterns to ensure the long-term scalability of the application.- Most notable project: the BlackFriday campaign page. Very lightweight, fully responsive and resource slim module that served as much as 1.5 mil. unique visitors in the first part of the BlackFriday campaign day (some 22.5k page views per second).Team Lead:- I was in charge with a team of 6 (5 developers + 1 QA). I created and assigned technical tasks according to the Project Managers and Product Owners non-technical specifications and we worked in an agile environment to ensure that deadlines were always met.- I reviewed the team code before pushing it to test & production servers.- I provided my knowledge and expertise to my team members to help their personal development and I ensured that everybody shared their personal knowledge and experience so that the team could grow as a whole.- Most notable project: HTML, CSS and JavaScript implementation of the website's unified UI - a collection of modular an reusable components as designed by our design department (colour palette, forms, buttons, alert boxes, typography etc).- Other notable achievement: heavy refactoring of legacy spaghetti javascript throughout the code base which resulted in a ~20% increase in performance in terms of page load times and resources delivered to the browser.Release Manager:I reviewed the code of the entire website department. After rechecking everything on the pre-production environments and ensured everything is ok, I deployed the code on the production servers.

I was part of the PHP team assigned with the development and maintenance of our B2C platform: Likeit.roMy responsibilities included:- development of web services to communicate with our B2B frameworks and other third-party web services: import of products, characteristics and images, placing orders to SAP, sending order information to shippers, retrieving shipment status form couriers;- development of other site-related back-end modules;- development of front-end modules and page redesign;- back-end and front-end code optimization;- bug-fixing & maintenance;- support for marketing and sales departments.

I developed front-end architectures for the following online shops:1. floria.ro:Changing their online shop framework, Floria.ro also needed a clean and fresh new look and a front-end architecture to cope with the growth of the mobile ascent of the web industry. Thus, the layout needed to be responsive, scaling from the wide fullHD desktop screens to smaller smartphone displays.UX was the biggest challenge of them all and switching interaction dynamically based on the user's display capabilities needed a huge amount of work. But with CSS media queries and dynamic JavaScript event binding, every module's size, position, purpose and interaction was developed thoughtfully and carefully.The front-end architecture is also multi-lingual and was developed using smarty's {t} tags, php's _() function and a custom JavaScript translation module. The english version of the website can be found at en.floria.ro2. russianshop.roA relaunch of another online shop, this front-end architecture is a clean and modern implementation, combining contrasting elements throughout its pages. Thin and narrow fonts right next to very strong titles and a saturated palette of red, black and white gives this layout a modern and expensive look.The fonts and icons were carefully selected to look even better on retina or high density displays.UX was also a point of focus: a fixed version of the header present on every page (except the homepage), highlighted category filters placed on the navigation drop-downs, a stripped and minimalistic checkout page, AJAX add-to-cart and other fancy animations, all developed to build an exquisite user experience.3. 3pitici.roA colorful layout, this font-end architecture is more than meets the eye. The website is very complex, yet the well-thought UX makes for a nice and playful experience.4. inghiozdan.roSimple front-end development with a colored palette and a minimalistic look. The website is developed with standard CSS and HTML, no fancy stuff.
