My passion for creating innovative and user-focused software lead me to work for over 2 years at MindsetHD, where I was the sole engineer responsible for everything frontend, backend, cloud and infrastructure related using Next.js, TypeScript, Express.js, MongoDB, and dozens of AWS services.

The core product that I created at MindsetHD was a motivational, interactive journaling platform that beautifully presents the user's answers to thought provoking questions against a dynamically created backdrop of nature footage and music.

A standout feature is the distinctive typewriter-style fade animation that can reveal up to four lines of text at once. It includes an innovative scrolling mechanism, activated at precise moments, powered by a binary search algorithm for instant line break detection. This method boosts performance and reduces DOM manipulations.

Additionally, I designed a custom video playback system that dynamically generates the right number of short video clips based on the anticipated duration of the typewriter effect, and merges them flawlessly in real-time, offering an uninterrupted, bufferless experience. This is made possible by strategic preloading and smooth transitions between video segments, guaranteeing seamless and efficient playback.

As part of working on MindsetHD, I also worked on the following things, just to name a few:

Created marketing flows including a custom webinar player, landing pages and checkout pages, all with in-depth analytics gathering and dozens of events and triggers based on user behavior that are processed using decoupled services at scale.
Created an in-house client-coach messaging portal using websocket serverless infrastructure with decoupled email notification service that enables users to respond directly to emails with replies automatically displayed in the dashboard.
Created admin tools to manage all the content of the platform, including uploading audio tracks and generating sound-wave visualizations.
Created a highly-scalable serverless HLS video transcoding system to generate the nature footage used by the platform alongside the marketing videos.
Created a highly scalable serverless websocket service, capable of handling thousands of concurrent users, that handles the events emitted by the analytics on the marketing pages and webinar players.
