Fullstack Developer
React · Next.js · Node.js · TypeScript

Building responsive and modern web interfaces with a strict focus on User Experience, Performance, Web Accessibility (A11y), and Clean Architecture.

I am a Fullstack Developer with a primary focus on building polished, user-centric web applications using React, Next.js, and TypeScript.

While I am capable of architecting entire applications from the database up, I am currently dedicating my expertise to the Frontend layer. My background in backend development (Node.js, Express.js, MongoDB, Prisma, PostgreSQL) gives me a unique edge — I don't just build UIs; I build "API-aware" interfaces that are robust, scalable, and easy for backend teams to integrate with.

Currently deepening my expertise in Web Accessibility (A11y/ARIA), SEO Optimization, Feature-Driven Architectural Design, and Advanced Server Components Patterns.

Efficient Server-State Management, Bot Protection & UI Dynamics

Tech: Next.js, TypeScript, Zod, React Hook Form, Tailwind CSS, Sonner

• Engineered a secure backend processing system using Next.js Server Actions integrated with a Telegram Bot API for real-time order and message notifications.
• Implemented an invisible anti-spam honeypot interceptor in contact forms to block automated bot inputs on the server side without disrupting the user experience or wasting API limits.
• Designed a universal type-safe i18n infrastructure combining Zod schema validation with a custom global JSON dictionary context for dynamic, multilingual error tracking.
• Optimized application accessibility (A11y) using native HTML5 dialog elements, keyboard focus traps (Esc dismissal), and modern scrollIntoView API for smooth page navigation.

Advanced Core Web Vitals, A11y & Feature-Driven Layout

Tech: Next.js 16 (App Router), React 19, Redux Toolkit, React Hook Form, Yup, Axios, Cookies, Sonner

• Scaled folder maintainability by implementing Feature-Driven Architecture for precise domain isolation.
• Reached high-end SEO and Accessibility (A11y) scores via semantic layouts, programmatic header-section mapping, strict screen-reader handling (aria-label, aria-hidden), and native HTML <dialog> components.
• Engineered optimized rendering through React Server Components (RSC) for public layouts alongside client-side state fetching with Redux Toolkit.
• Handled advanced validation schemas and secure session management via cookie serialization.

Monorepo Workspace & Relational DB Modeling

Tech: React, React Router, Tailwind CSS, TanStack Query, Express.js, Prisma, PostgreSQL

• Developed an interactive, dynamic form builder and live form filler with instant response validation and analysis components.
• Structured the project codebase as a scalable monorepo layout utilizing npm/pnpm workspaces for clean package management.
• Designed and migrated a relational database schema using PostgreSQL hosted on Neon, managed entirely via Prisma ORM.
• Handled custom, adaptive styling layout rules entirely from scratch with Tailwind CSS.
