[Frontend-focused Full-Stack Engineer]
Tatiana Arbuz
I build web applications with React and Next.js, focusing on architecture, performance and scalable end-to-end integrations.
About me
[Less talk — more shipped features.]
I’m a frontend-focused full-stack engineer. I build web applications with React and Next.js (App Router, TypeScript) with a strong focus on architecture (Feature-Sliced Design), UX and performance (SSR/ISR). Experience with backend (NestJS, Laravel) and DevOps (Docker, GitLab CI/CD) gives me a holistic view of the product and helps me design reliable end-to-end integrations and scalable solutions.
My core priorities:
- Robust architecture
- User-friendly experience
- Process automation
In my work I focus on system reliability, clear interfaces and automation of routine tasks. I keep learning, value direct, concrete communication and aim for results that create tangible value for both the business and the team.

Experience
[Experience is tough problems I’ve already solved.]
DMZ Home Construct | 2025 · contract
Frontend-focused Full-Stack Engineer
(Construction company, SAMPO residential complex)
Designed and implemented a headless architecture based on Next.js App Router and Payload CMS v3 for content-heavy pages of the residential complex website. Set up Payload CMS from scratch: data structures, collections and access control. Replaced multiple client-side request chains with a unified server-side resolver layer and caching. Configured ISR and tag-based cache invalidation (revalidateTag) and built a modular page-loading system with declarative content management.
🏆 Result: Improved page load speed and stability for the residential complex website and simplified content operations thanks to predictable architecture and automated data refresh.
CPABOX | 2022–2025
Frontend-focused Full-Stack Engineer
(SaaS platform for affiliate traffic automation)
Designed the frontend architecture ensuring consistent API contracts and predictable UI behaviour. Introduced Zustand for shared state management across modules and screens. Built and optimised an analytics dashboard (ApexCharts) integrated with Keitaro API. Developed a Telegram Web App and a NestJS service for WHOIS checks and domain synchronisation. Increased UI consistency and maintainability by refactoring MUI components and theming.
🏆 Result: Delivered a stable and fast analytics dashboard and automated routine domain checks through a new communication channel — Telegram.
Remotza.tech | 2021–2022
Backend / Full-Stack Developer
(Custom software development)
Developed REST APIs and integrations in Laravel for multiple client projects. Worked closely with UI teams on Vue.js components and their integration with the backend. Optimised data structures and caching strategies in PostgreSQL and Redis to reduce database load.
🏆 Result: Improved API efficiency and reduced data-loading time in client interfaces through optimised queries and caching.
AOPSRM | 2020–2021
Full-Stack Developer
(NGO supporting ostomy patients in Moldova)
Built a multilingual website in React and designed a custom CMS in Laravel for content management. Set up CI/CD in GitLab using Docker, enabling predictable deployments and fast content updates.
🏆 Result: Delivered a turnkey website with CMS — from business logic to deployment — allowing the organisation to publish content and communicate with the audience independently, without external developers.
Education
[Experience in finance doesn’t compete with code — it makes decisions more precise.]
Russian University of Cooperation | Accounting and Finance
Background in finance helps me design business logic, metrics and reporting flows more accurately in complex web systems.
Projects
[Projects are measured not in lines of code, but in value.]
This website is not just a résumé — it’s an open-source product called Folio Metrics that reflects my approach to architecture, analytics and product thinking.
