I have worked with clients around the world for many years, specializing in building applications using Bubble.io. This platform allows me to develop projects ten times faster and at a fraction of the cost. However, I am also skilled in designing and building web applications in other programming languages. Here are some examples of my work: - **kagent.com**: Built with Bubble.io, Facebook’s Graph API, SendGrid, and Mailchimp. - **zensupplies.com**: Built with Docker, PHP 7, Yii2, Redis, MySQL, RabbitMQ, Amazon services, Elastic Search, SendGrid, Sentry.io, Logstash, Kibana, and Angular.js. - **praction.co**: Built with Bubble.io, Stripe, Zapier, SendGrid, Sparklite, UserGuiding, HelpScout, and Mixpanel. - **app.jobso.ca**: An AI-powered app built with Bubble.io and OpenAI. - **independentspeculator.com**: Built with HTML, CSS, JavaScript, and CMS Magento (PHP). - **meetdandy.com**: Built on WordPress. Many of these projects required development skills and expertise in design and UX/UI. I prioritize the design process, collaborating with you to wireframe your ideas into the best possible user experience. I primarily use Figma for my design work. Numerous companies have utilized my skills as their outsourced CTO, taking advantage of my experience in both business and technology. I help them align their technology strategy with their business objectives, ensuring they do not lose sight of their goals. I have also assisted many startups in developing their initial MVPs smartly and cost-effectively. Additionally, I specialize in workflow automation using webhooks, APIs, and no-code tools like Zapier and Integromat. I have successfully built complex automation that integrates a company's production databases with its marketing, sales, and customer support divisions.
