Experience
CC-ONRC.ro - Document Retrieval Service
http://cc-onrc.roA service platform I founded, built, and marketed myself. Every page is a landing page: paid search traffic arrives with sharp commercial intent, and the page has to answer the query, establish trust in a category where users are wary, and convert—on mobile, in under a second. I handled WordPress and WooCommerce development, Romanian direct-response copy, Google Ads campaigns and bidding strategy, and analytics and conversion tracking for all of it. Because I'm spending my own budget, every layout, headline, and form change is validated against CPA rather than opinion.
AG5 Skills Management Software
https://www.ag5.com/AG5 is a SaaS that allows you to visualize and track your workforce skills in a centralized skills hub that integrates with your HR and learning systems. I was the WordPress developer for the presentation website and liaised with the head of marketing to improve the website's performance, design, and features, as well as fix various issues.
Artist Website for DJ John Junior
https://johnjunior.ro/A modern, artist-focused website built for DJ and producer John Junior, featuring music releases, press kits, news updates, and event highlights. It's designed for clarity, fast navigation, and a visually engaging artist brand experience.
Service Marketplace Solution for WordPress

• Built and managed the development team.

• Released monthly updates for the theme and plugins.
• Integrated dozens of external REST APIs.
• Built the REST API for the iOS and Android apps.

Online Store for Valerio
An online store for an established local fashion brand. I was responsible for everything, from proposing technology solutions to implementing them, as well as providing employee training on products and order management, and running the first Facebook Ads campaigns.
Dental Clinic Website for Dr. Emilia Mosnegutu
A clean, lightweight WordPress presentation website built with Brizy for a local dental clinic.
The client’s challenge was that outdated online directory listings were showing incorrect phone numbers and addresses, causing patients to contact the wrong location. Because many directories wouldn’t update or respond, I registered a new domain and created a fresh website designed to outrank the old listings. After launching the site, adding the clinic to Google Maps, and updating the directories we could access, the correct information quickly rose to the top of search results—effectively solving the issue.

RSS News Feeds Aggregator
A news aggregator website, automatically collecting and reposting news from around 20 websites. As a WordPress developer, I was in charge of finding the right theme and plugins, configuring and customizing them to meet the client's needs, and training him to add new RSS sources and manage the imported content. Additionally, I launched the site to a freshly configured server, setting up automatic back-ups and handling occasional updates.
