    With over 8+ years of hands-on experience in developing web applications, I specialize in creating cutting-edge, user-centric solutions that deliver exceptional functionality and performance. My expertise spans modern 𝐉𝐚𝐯𝐚𝐒𝐜𝐫𝐢𝐩𝐭 frameworks like 𝐑𝐞𝐚𝐜𝐭, 𝐍𝐞𝐱𝐭.𝐣𝐬, 𝐕𝐮𝐞.𝐣𝐬, and 𝐀𝐧𝐠𝐮𝐥𝐚𝐫, as well as robust backend frameworks such as 𝐍𝐨𝐝𝐞.𝐣𝐬, 𝐄𝐱𝐩𝐫𝐞𝐬𝐬, and 𝐏𝐲𝐭𝐡𝐨𝐧’𝐬 𝐃𝐣𝐚𝐧𝐠𝐨 𝐚𝐧𝐝 𝐅𝐥𝐚𝐬𝐤. Leveraging these technologies, I ensure secure, scalable, and high-performance applications tailored to meet diverse business needs. 💼 Projects I’ve Contributed To 💼 ✨ Designed to Run ✨ I collaborated with Designed to Run, a platform dedicated to supporting Democratic campaigns and advocacy organizations, to create impactful websites aimed at attracting donors, engaging volunteers, and amplifying campaign efforts. Leveraging 𝐑𝐞𝐚𝐜𝐭 and 𝐆𝐚𝐭𝐬𝐛𝐲, I optimized website performance and ensured an intuitive user experience for supporters. By integrating 𝐀𝐏𝐈-𝐝𝐫𝐢𝐯𝐞𝐧 workflows, I automated complex campaign data processes, significantly improving efficiency and reducing manual effort by 50%. Additionally, I developed scalable templates adaptable for multiple campaigns, ensuring the platform met the dynamic needs of political organizations. 🌿 StrainBrain 🌿 At StrainBrain, an innovative platform for the cannabis industry, I played a key role in developing the AI Budtender, an AI-powered recommendation engine designed to help consumers navigate extensive product catalogs. I implemented advanced data pipelines using 𝐍𝐨𝐝𝐞.𝐣𝐬 and 𝐄𝐱𝐩𝐫𝐞𝐬𝐬𝐉𝐬, enhancing recommendation accuracy and driving a 23% increase in shopper spending. I also worked on the Boosts feature, which empowers brands to gain visibility in retail environments, achieving up to a 12x return on ad spend. Through secure 𝐑𝐄𝐒𝐓𝐟𝐮𝐥 𝐀𝐏𝐈, I ensured seamless communication between retailers and the platform while maintaining strict compliance with industry standards.
