SUMMARY
Full Stack Developer (.NET / React / Next.js) with over 3.5 years of experience in developing scalable web
applications (CRM, E-commerce, SaaS). Specializing in building high-performance user interfaces with
Next.js / React and developing robust server-side architecture using .NET (C#) and Node.js. Experienced
across all development phases: from optimizing Core Web Vitals (LCP, CLS) and configuring advanced
rendering strategies (SSR/SSG/ISR) to designing REST APIs, microservices, and optimizing database
queries.

TECHNICAL SKILLS
● Backend: C#, .NET 8+, Node.js, NestJS, ASP.NET Core Web API / MVC
● Frontend: Next.js, React, TypeScript, JavaScript, Redux Toolkit, Tailwind CSS
● Databases & ORM: PostgreSQL, MongoDB, MySQL, MS SQL Server, Entity Framework Core
● Tools & Infrastructure: REST API, SignalR, RabbitMQ, Docker, Git, xUnit, Jira, Agile / Scrum

WORK EXPERIENCE
Full-Stack Developer | Independent Contractor / Freelance | December 2025 – Present

● Scalable UI Architecture: Designed a modular system of component templates and interfaces for
E-Commerce, HoReCa, and business automation sectors, streamlining development timelines and
deploying 100+ content-rich web pages.
● E-Commerce Infrastructure: Architected web platforms, integrated payment gateways (Stripe),
and implemented secure authentication flows (Access/Refresh JWT tokens, sessions, Email
Confirmation).
● Frontend Performance: Optimized client-side interfaces using Next.js/React: implemented
dynamic component loading (Dynamic Imports), flexible rendering strategies (SSR/SSG/ISR), and
static asset optimization, enhancing Core Web Vitals and boosting page load speed by ~35%.
● Database Optimization & Refactoring: Executed relational database refactoring and performance
tuning. Successfully migrated legacy database schemas to full Unicode (utf8mb4) support,
eliminating validation errors, ensuring multi-language data consistency, and improving
synchronization stability between the backend and client admin panels.
● Data Extraction Modules: Engineered and deployed modules for automated retrieval and
exporting of full commit histories from external repositories via GitHub API and Azure DevOps API,
providing deep process logging and maintaining precise codebase change records.
Tech Stack: Next.js, React, Tailwind CSS, .NET 8, Node.js, PostgreSQL, MySQL, EF Core.

Full-Stack Developer | Ship-cheaper | December 2024 – December 2025

● Enterprise Integration: Developed modules for integrating microservices with external B2B
platforms, implementing asynchronous data synchronization via RabbitMQ message broker.
● Frontend Development: Created interactive interfaces and order management pages using React
+ TypeScript, introducing reusable components to simplify code maintainability and elevate UX.

● Reliability & Testing: Refactored and optimized legacy source code. Covered critical business
logic with Unit tests (xUnit), minimizing bug counts in legacy modules and increasing overall system
reliability.
Tech Stack: C#, .NET 8, ASP.NET Core Web API, React, TypeScript, RabbitMQ, PostgreSQL, EF Core,
xUnit, Docker.

Full-Stack Developer | Rumedy | September 2023 – December 2024

● Admin Platform Development: Developed and extended administration modules for a large-scale
CRM system in the restaurant automation sector, enabling operators and managers to flexibly
configure venue settings, menu catalogs, and access permissions.
● Real-Time Integration: Configured asynchronous data exchange between the .NET backend and
the Next.js client-side via SignalR, delivering instant, real-time updates for order statuses.
● DB Performance: Refactored heavy LINQ queries within EF Core, systematically resolving N+1
issues in Many-to-Many relationships, which significantly accelerated admin dashboard page
loading speeds.
Tech Stack: Next.js, React, TypeScript, .NET 7, Web API, Node.js, NestJS, SignalR, PostgreSQL, xUnit,
EF Core.

Full-Stack Developer | Flai Analytics | November 2022 – September 2023

● Backend Integration & API: Extended and maintained server-side logic using .NET 6. Modified
REST API controllers, configured incoming JSON model validation, and implemented endpoints to
seamlessly integrate the frontend layer with the database.
● Analytics Dashboard Implementation: Developed the interface layer of an analytical platform
using ASP.NET MVC. Implemented rendering for complex dynamic charts, interactive tables, and
analytical reports, ensuring precise binding with real-world TikTok scraped data.
● Code Refactoring & Optimization: Refactored inherited "prototype-stage" controller code and
frontend scripts. Cleared the codebase of duplication, structured request routing, and decoupled
validation logic, which reduced form-submission errors and accelerated new feature development by
approximately 25%.
Tech Stack: .NET 6, C#, ASP.NET MVC, MS SQL Server, JavaScript (ES6), Bootstrap.
