About me https://github.com/thejustvic​
​
Senior Front-End Engineer | System Architect of Zero-Inertia Interfaces​

I don't just write code, I engineer digital ecosystems where complex business logic meets
seamless user intent. With 4+ years of professional experience across the React evolution (v15 to
v19), my focus is on eliminating system "lag" - both in performance and in the development
lifecycle.​

Core Expertise in Complexity Management:​

High-Precision State Geometry: Engineered an interactive, Google Calendar-style weekly
scheduler with complex event overlapping, real-time resizing, and drag-and-drop synchronization.​

Visual Logic Builders: Architected ad-funnel systems using react-diagrams, transforming abstract
sales flows into intuitive, canvas-based visual tools with integrated team management.​

Geospatial Data Visualization: Developed interactive mapping systems for dynamic path-building
across regions, focusing on instant UI response to complex data inputs.​

Automated Quality Assurance: Shifted manual testing cycles to high-velocity automated suites
using Cypress, ensuring 100% reliability of the "signal" from code to user.
​
Latest work My latest architectural "save" showcases a 3D-visualized productivity environment.​

Dynamic Environments: Real-time 3D scenes synchronized with seasonal states (Winter to
Autumn) featuring free-roam navigation (jump/fly).​

Real-time Collaboration: Multi-team infrastructure with instant chat, emoji-reactions, and
invitation-based scaling.​

Adaptive UI: Fully customizable workspace with resizable layouts, theme modulation, and
real-time state updates across checklists and card-based workflows.​

Stack & Tools: TypeScript, Next.js, Supabase, Three.js, MobX, Tailwind, Turbopack

KEY SKILLS​ Core Architecture: React (v15–19), TypeScript, Next.js (14/15), JavaScript (ES6+)
State & Data Flow: Redux (Thunk/Saga), MobX, React Hooks, Context API
Performance & Rendering: SSR, Turbopack, Three.js (3D Visualization), i18n Optimization​
