Juan G.

QA developer in Spain (UTC+2)

Hi! I'm Juan Manuel, a dedicated and results-driven professional with a strong background in Quality Assurance and Test Automation. Over the past few years, I've had the privilege of working in dynamic international environments, contributing significantly to the success of two prominent companies, Cigna and Solera Inc. My experience and expertise span a wide range of responsibilities and technologies, making me a versatile and effective team member. At Cigna, I have been leading the automation squad, where I played a pivotal role in designing and implementing a robust automated framework for critical projects. My responsibilities also included maintaining automated test cases and CI/CD pipelines to ensure a seamless quality assurance life cycle, with a specific focus on User Acceptance Testing (UAT) environments. I took on the challenge of establishing and optimizing QA processes, both manual and automated, for various APIs, front-end applications, and mobile apps from the ground up. To enhance efficiency, I introduced quality gates, Key Performance Indicators (KPIs), and collaborated with the team to create effective user stories, applying Behavior-Driven Development (BDD) principles for accelerated development and QA processes while keeping product documentation up-to-date. Prior to my role at Cigna, I served as a Senior QA Automation Engineer at Solera Inc., where I was involved in numerous tasks, including test specification design, feature testing as part of sprint activities, and the analysis of test results. My expertise extended to various automation tools and technologies, such as Selenium Webdriver, Cypress, Playwright, Cucumber, TestNG, Maven, Java, Python, JavaScript, C#, Rest-Assured, Postman, Newman, Swagger, ReadyAPI, Appium, Jmeter, Jenkins, Bamboo, and Azure Cloud. I effectively utilized tools like JIRA, TestRail, BitBucket, GIT, and Confluence to streamline project management and collaboration. With a proven track record in leading automation initiatives, optimizing QA processes, and mastering a wide array of testing tools and methodologies, I am eager to bring my skills and experiences to a new challenge. I am confident that my background and achievements make me a valuable asset to any team, and I look forward to contributing my expertise to help drive success in my next endeavor.

Ventsislav P.

QA developer in Spain (UTC+1)

With over 10 years in web development, I've enjoyed contributing to various stages of product development across multiple projects. This experience has not only grown my technical skills but also my ability to work well in a team. As a Front-End Developer for the last 5 years, I've worked with fantastic teams and a broad range of technologies. My work involves crafting user-friendly interfaces with HTML, CSS, JavaScript, and integrating data from different APIs. I've extensively used frameworks and languages like, Angular, AngularJS, TypeScript, and Ionic to create engaging web and mobile applications that are easy to use and follow Agile methodologies. I've also dived into end-to-end (E2E) testing with Cypress and Playwright (which in my view is better than cypress ). This has enhanced my skills in ensuring our applications are both reliable and perform well, improving the overall product quality. My curiosity and love for learning have led me to explore the fascinating world of Data Science. I am intrigued by the potential of Statistics, Machine Learning, and AI to unearth insights from data, which could enrich user experiences and decision-making processes in the digital products we create. Passionate about AI and have explored fine-tuning AI models with tools like OpenAI, Mistral, and Llama2 to solve different problems.(only from curiosity not in production ) I thrive in positive environments where ideas are freely shared and learning is constant. Though self-motivated and capable of working independently, I actively seek collaboration with colleagues who share a passion for technology. I'm always open to connect and explore how we can work together on exciting projects!
