Lexik
Role:Software Development Consultant & Full-Stack Engineer
Learners experience high attrition when confronted with dense German grammatical rules (cases, genders, prepositions), leading to rapid drop-off in conventional language apps.
Developed a real-time visual parsing syntax engine in Flutter coupled with an event-driven Node.js backend to deliver spaced repetition prompts and maintain high daily engagement.
Turned intimidating grammatical structures into clear visual memory anchors, significantly boosting learner retention and encouraging consistent 10-minute daily practice habits.
Product Architecture
Lexik is a modern language-learning product built to demystify German grammar (A1-B2). It replaces traditional dry textbook memorization with a visual color-coded grammar engine and dynamic daily micro-learning challenges.

Visual Color-Coded Syntax Engine
Developed an organic parsing algorithm that visually color-codes sentence structural components (subjects, direct objects, dative cases, prepositions) in real time.
Context-Aware Notification Dispatcher
Architected a Node.js background routine that triggers micro-practice challenges at optimized daily intervals, reinforcing spaced-repetition memory retention.
Asynchronous Offline-First Synchronization
Implemented offline lesson caching that enables uninterrupted learning on transit or without internet, gracefully syncing progression data whenever connectivity returns.
