As a seasoned Email and CRM Developer with over eight years of experience in innovative corporate, recruitment, fintech, gaming, and agency environments, I bring a passion for creating efficient, visually appealing, and engaging email campaigns. With over 14 years of hands-on HTML/CSS development experience and six years of experience with scripting and templating languages (LIQUID, AMPscript, Handlebars), I specialise in building responsive and interactive communications, as well as dynamic templates tailored for personalised customer engagement. I create custom drag-and-drop modules through coding or confidently tweak existing module options without the need for code. I also advise teams on enhancing personalisation strategies by thinking outside the box, leveraging dynamic content and conditional logic to improve customer targeting and engagement. I am equally comfortable collaborating closely with cross-functional teams or working autonomously to deliver high-quality solutions. I’ve developed a wide range of email campaigns, including onboarding, automated workflows, lifecycle journeys, re-engagement, retention, win-back, promotional, and transactional emails, each built with a focus on performance, responsiveness, and user experience. I excel in email development using tools such as ExactTarget, Litmus, Salesforce Marketing Cloud, Braze, Bloomreach, Customer.io, and Blueshift. I am an organised and methodical self‑starter, highly motivated to manage multiple projects simultaneously. With strong problem-solving skills and the ability to remain composed under pressure, I consistently identify and implement solutions efficiently. My attention to detail, critical thinking, and ability to adapt to unfamiliar tasks enable me to thrive in fast-paced, dynamic environments. I work quickly and accurately, whether independently or in a team, and take full ownership of my work, always eager to take on additional responsibilities.
