Location: Bielsko-Biała, Śląskie, Poland Profile: https://flows.cv/borismanzhela As a full-stack product designer and front-end developer, I thrive in creating innovative web interfaces, specializing in B2B, SaaS, and CRM-like systems. I’m from Kyiv but moved to Bielsko-Biala, Poland a year ago. In my role, I proactively seek opportunities to elevate the user experience and enhance system efficiency. My approach is deeply rooted in data-driven decision-making, utilizing A/B testing and CX/UI metrics to guide and validate my design choices. My development skills are not just about writing code but crafting solutions. I take pride in delivering clean, maintainable code, and developing responsive, accessible, high-performance interfaces using the latest but stable technologies. I have initiated and successfully led the front-end development of projects with different stacks adapting swiftly to our product market fit by testing hypotheses. I am always looking for new challenges and opportunities in creating user-centric yet efficient digital products. ## Work Experience ### UX/UI Product Designer & Front End Developer @ Markify - Global trademark services Jan 2024 – Present | Bielsko-Biała, Śląskie, Poland ### UX/UI Product Designer & Front End Developer @ Translate.com Jan 2021 – Jan 2024 | Bielsko-Biała, Śląskie, Poland Core responsibilities in this position: UX Research, UI Design, Interaction Design, front-end development, and using both generative and evaluative research methods. I played as a CRO specialist also to improve CR/CPL/CPA/CPC metrics with a tight budget within current organic non-commercial traffic. As a designer, I was responsible for designing and delivering world-class digital experiences across different environments using Design Thinking and a Design Sprints approach. That included creating project briefs, user flow diagrams, wireframes, high-fidelity prototypes, project planning documentation and milestones, interaction design documentation, design systems/style guides, and micro-interaction design. As a front-end developer, I helped build data-heavy web applications with complex user interfaces in various roles. Development of reusable components for React, Next.js, and Laravel; Writing maintainable and easy-to-understand code; Collaboration with product managers, product owners, stakeholders, DevOps, SEO specialists, and clients to build, test and deploy high-quality solutions; Implementation and maintenance of accessibility following WCAG, ADA, Section 504/508, and AODA standards; I supported projects with different stacks. - Backend: Angular, Codeigniter, Laravel, Slim, Yii2, - CSS Frameworks: Tailwind, Bootstrap - CSS pre-processors: LESS, SCSS, Sass, Stylus or CSS - Javascript frameworks and libraries: ES6.9, Angular 4, Vue 2, React (Next.js), jQuery - Bundlers: Gulp, Webpack, ESBuild - CI: Jenkins, GitLab, or neither - Environment: Local (Xammp, Apache, Express), Vagrant, Docker Given that I was responsible for writing code and design, I was able to deliver the design solutions right in the code so we could verify our business decision ASAP. ### UX/UI Product Designer @ Translate.com Jan 2021 – Jan 2021 | Kyiv, Kyiv City, Ukraine Design, create, and implement the vision of translation apps for iOS and Android. - Delivered a UX vision and plan for evolutionary, iterative updates. - Brainstorming, wireframing, and developing data-driven designs for digital experiences. - Design information architecture and interfaces for web services and mobile apps. - Created clickable high-fidelity and low-fidelity mockups with tools like Figma or Adobe XD. - Ensuring usability, brand consistency, accessibility, and a unified visual language across all products. - Contributing to and maintaining the company’s design system. - Collaborating with cross-functional teams, including UX, copy, research, development, product, and other stakeholders. - Presenting and defending designs and key milestone deliverables to the team and executive-level stakeholders. ### Middle Frontend Developer @ Translate.com Jan 2019 – Jan 2021 Our team embarked on a challenging venture of integrating various acquired projects. The portfolio was diverse: Codeigniter, Angular, native iOS/Android apps, and an assortment of microsites built on exotic frameworks and CMS. My objective was twofold: 1) Orchestrate a migration and update of the front-end architecture for our key products - transitioning from a blend of Codeigniter, Slim, WordPress, JavaScript, plain HTML, and Angular to a more contemporary, cohesive stack. 2) Bolstering our SEO efforts, focusing on elevating page metrics and structuring to drive organic traffic growth. Leading the helm of the migration from Codeigniter to Laravel, I used the Blade templating engine, meticulously ensuring that the transition was seamless and visually non-disruptive to our user base. My approach to refactoring JavaScript was holistic - introducing Sass as a replacement for CSS, anchored on principles of clarity, and maintainability. Leveraging my foundational knowledge in PHP, I minimized the need for backend team intervention by autonomously expanding the API and crafting custom methods to fulfill specific requirements. The fruits of these extensive efforts were multifold: - We witnessed a dramatic 5-fold reduction in page loading times, a testament to the enhanced efficiency of the new stack. - Perfect scores in page/website speed metrics. All in the green zone. - Feature deployment saw a notable acceleration, thanks to the robustness and versatility of the updated codebase. - Remarkable 220% (370% overall after migrating) year-over-year surge in organic traffic. - Significantly, we also saw a substantial decrease in churn rates, underscoring the heightened stability of our revamped products. ### Frontend Developer @ The APP Solutions Jan 2015 – Jan 2019 | Ukraine - UI prototyping in AxureRP - Converting PSD/Sketch to valid HTML5 code - Making Wordpress themes - Adding responsive features to ready made templates - Page speed optimization Tech stack: HTML(Jade), CSS (LESS), GIT, Javascript(jQuery), Gulp ### Growth Product Manager @ Ukrcolor Jan 2017 – Jan 2019 | Kiev Region, Ukraine Boosted income through an iterative process of improving UX and CX, tweaking paid marketing strategy and SEO activities (including ghostwriting and paid link posting) ### Owner @ CoachStack Jan 2017 – Jan 2018 | Ukraine Testing the hypothesis that an online gaming training platform can be profitable.
