GitHubBuild
I turn product and client requirements into working web products, from technical decisions and implementation to usable content and application workflows.
Caius Muntean
Web Product & Quality Engineer
Web Products Integrations Quality
I build, integrate and test reliable web products, from real-world problems to production.
01
Profile
I have 8+ years of experience working with real production web products, with a strong focus on quality and solving technical and customer-facing problems across browsers, WordPress, custom code, APIs, integrations, and third-party systems.
At Elegant Themes, I investigate issues across real customer environments, reproducing browser and configuration-dependent behavior, tracing problems through the DOM, console, network activity, plugins, themes, and application behavior, then turning the findings into practical solutions or actionable product feedback.
Alongside that production experience, I build and integrate web products using TypeScript, React, Next.js, WordPress, PHP, and REST APIs, with automated UI and API testing, CI/CD, and production validation built into how I deliver them.
02
Capabilities
I build web products, integrate and troubleshoot the systems around them, and validate what reaches production.
Integrate & Solve
I connect web platforms, APIs, and third-party services, then investigate failures across their boundaries. I reproduce ambiguous production problems, isolate root causes, and turn the evidence into practical fixes or actionable escalations.
Test & Deliver
I validate behavior at the right layer, automate important user and API paths, and carry those checks through releases and production. Quality stays part of implementation and delivery.

Selected Projects
Client and independent products showing what I have implemented, integrated, validated, and delivered.
Stomagia
A dental-clinic client website delivered end to end with headless WordPress and Next.js, from content and UX/UI through implementation, integrations, validation, and production delivery.
Ownership: End-to-end delivery across content, design, WordPress/PHP CMS and APIs, Next.js frontend, validation, and release.
- WordPress-to-Next.js content delivery and a custom Google reviews integration, with routine publishing kept inside the CMS.
- Playwright and API validation, Lighthouse checks, and a Preview → validation → Production workflow for structural releases.
Stack: WordPress · PHP · REST APIs · Next.js · GitHub Actions · Playwright
Deploy & Test
A WordPress control surface that lets trusted users run configured GitHub Actions deployment and test workflows without GitHub access or personal access tokens.
Ownership: Sole creator · Product definition, WordPress/PHP implementation, GitHub integration, validation, documentation, packaging, and release.
- GitHub App/API/Actions integration with explicit role, credential, concurrency, failure, and audit boundaries.
- PHPUnit and 10 Playwright tests, plus packaged-release gates; defect fixes are retained as regression coverage.
Stack: WordPress · PHP · GitHub App/API/Actions · PHPUnit · Playwright
SEO & Social
An editor-managed WordPress product that keeps stored defaults and overrides distinct, resolves them into a predictable REST contract, and supplies structured data to a separately owned frontend.
Ownership: Sole creator · Product definition, WordPress/PHP implementation, REST contract design, validation, documentation, packaging, and release.
- The plugin owns editor workflows and structured data; the consuming frontend owns rendering and public URLs.
- PHPUnit, REST-contract validation, 23 Playwright admin tests, and packaged-release checks protect editor and consumer behavior.

Building Octav
A substantially implemented headless WordPress and Next.js website for a construction and property business, with client-editable business, project, and SEO/social content.
Ownership: Client website implementation across the CMS model, content workflows, responsive frontend, SEO/social setup, and deployment preparation.
- Tailored WordPress fields and publishing workflows connected to a custom responsive Next.js frontend.
- A public preview demonstrates the implemented product; final client content, minor corrections, and SEO metadata remain in progress.

Experience
Professional experience in production troubleshooting and client web delivery, with additional project-based QA automation.
Professional Experience
Technical Support Engineer - Elegant Themes
Customer-facing production troubleshooting at the boundary between users, WordPress and Divi behavior, browsers, custom code, and third-party integrations.
- Turn incomplete user reports into reproducible cases, then isolate product defects from configuration, environment, browser, plugin/theme, custom-code, and integration issues.
- Debug frontend and WordPress behavior using DOM/CSS inspection, console and network evidence, logs, and PHP or custom-code analysis where supported; validate fixes and practical workarounds.
- Communicate technical findings clearly and escalate actionable defects or regressions with evidence for product teams.
Freelance Web Developer - Independent Projects
Client website delivery from requirements and implementation through testing, deployment, handoff, and maintenance.
- Translated client requirements into WordPress presentation and e-commerce websites with practical, maintainable content workflows.
- Built custom themes and functionality with WordPress, PHP, HTML, CSS, and JavaScript, including responsive, cross-browser, form, and CMS behavior.
- Managed deployment, handoff, production troubleshooting, and ongoing communication across hosting, configuration, plugin, and theme boundaries.
Project-Based Training
EPAM QA Automation Program / Project
Project-based training · Diagnostic clinic web application
Sole QA role within a cross-functional training project, responsible for test strategy, release-risk coverage, automation, and defect investigation.
- Planned positive, negative, integration, and regression coverage for registration, appointments, results, authentication, role-based access, and data integrity.
- Built UI and API automation with Java, Selenide/Selenium, TestNG, and REST Assured.
- Investigated and triaged defects, documented reproducible evidence, and supported sprint and release-readiness decisions within the project team.
