Work experience Experience

May 2025 - present
STRADA - QA & Automation Engineer

Performed comprehensive manual testing of both web and mobile application
versions, ensuring consistency and quality across multiple platforms.

Conducted functional and visual regression testing across different environments,
including Development (dev) and Production (prod), to maintain application stability.

Systematically tracked and reported defects in ClickUp, managing the full lifecycle of
issues from discovery to resolution.

STRADA (continued)

May 2025 - present
Spearheaded the creation of an automated API testing framework using Jest.js,
leveraging AI-driven prompt engineering with Claude to assist in writing test cases,
generating diverse test data, and optimizing testing logic.

Implemented Continuous Integration (CI) through GitHub Actions, establishing
automated test execution triggered by development workflows.

Developed a custom integration to automatically generate comprehensive test reports
and deliver notifications directly to Discord channels via webhook.

Engineered an AI-powered content bot using Claude and Gemini API, automating the
generation and publishing of high-quality platform posts.

DAR Garden - Mobile Front-End Developer & QA Engineer

May 2025 - present
Contributed to the development of a cross-platform mobile application using React Native,
ensuring consistent UI/UX across mobile platforms.

Provided architectural oversight and technical direction for AI-assisted workflows (Claude
Code), enforcing clean code principles, component reusability, and modular design.

Architected component structures by identifying duplication risks and guiding the
creation of shared, reusable components and global CSS patterns.

Collaborated on UI/UX design concepts, translating visual mockups into clean,
maintainable mobile application code.

Identified functional and visual defects through hands-on manual testing, subsequently
leveraging Claude Code to analyze log files, perform root-cause analysis, and deploy fixes
within the React Native codebase.

DOSIJEM - Solo Front-End Developer

October 2025 - present
Successfully architected and developed the entire front-end application from scratch using
Next.js and Material UI (MUI), delivering a high-performance web experience.

Translated complex Figma mockups into a fully responsive user interface, ensuring pixel-perfect
layout adaptation and seamless performance across desktop, tablet, and mobile devices.

Collaborated closely with the UI/UX designer to align technical implementation with visual
concepts, sourcing and implementing optimized component animations.

Integrated RESTful APIs to facilitate seamless data communication (fetching and sending data)
between the client-side interface and the backend infrastructure.

Enforced clean code principles and DRY architecture, optimizing performance and eliminating
code duplication to ensure high long-term maintainability.

Conducted end-to-end self-testing and debugging, independently identifying and deploying
fixes to maintain absolute application stability.

MINECLUB - Solo Front-End Developer

October 2024 - present
Developed the initial responsive web platform from scratch using native React and MUI,
ensuring layout adaptation across mobile, tablet, and desktop from Figma mockups.

Architected the next-generation web application (currently on hold), successfully building
multi-page layouts and integrating SSO authentication via Google, Steam, and Discord.

Optimized server-state management by implementing React Query for efficient data fetching,
caching, and seamless asynchronous background updates with the backend API.
