Dario M.

Hi, I'm Dario, a software engineer from Zagreb, Croatia, with an MSc in Software Engineering and almost a decade of experience working with software, data, testing, and digital products. My work sits at the intersection of technology, quality, language, and AI. I help clients evaluate whether software, content, translations, and AI-generated outputs are actually correct, usable, and consistent. ### What I currently do **QA & Software Testing** • Web and mobile application testing • Functional, regression, UI and cross-platform testing • Bug identification, reproduction and detailed reporting • API and integration testing • Test-case creation and quality review • Code and implementation review from a QA perspective **AI Evaluation & Data Work** • Evaluating AI-generated responses and technical content • Prompt and response review • Data annotation and labeling • Checking AI outputs for accuracy, consistency, relevance and instruction-following • Technical evaluation of software/code generated or assisted by AI tools **Translation & Localization** • Croatian / Bosnian / Serbian ↔ English • Technical and software-related translation • UI and product localization • Translation QA and proofreading • Terminology and consistency review • Checking whether translated content sounds natural and appropriate for its context **Technical Review & Software Engineering** • Code reviews and technical audits • Frontend and full-stack development • Vue.js, React.js, TypeScript and Python • FastAPI, Flask, Node.js and PostgreSQL • Understanding existing codebases and identifying practical improvements My software-engineering background is important because I don't approach these tasks only from a language or testing perspective. When I review a product, translation, AI response, or piece of code, I can also understand the technical context behind it. I regularly use modern AI-assisted development tools in my workflow, but I always verify the result myself. The goal is not simply to produce output faster, it's to make sure the final result is accurate, reliable and fit for the actual use case. I'm particularly interested in long-term or recurring work involving QA, AI evaluation, software testing, technical translation/localization, code review, and related technology projects. If you need someone who can understand both the technical details and the end-user context, I'd be happy to take a look at your project.
