Byborg is a digital entertainment and technology group behind a large portfolio of adult streaming, VOD, creator-economy and AI companion platforms, including Playboy, Sex.com, Adult Time, LiveJasmin, The Million Roses, Cuties.ai, Kiiroo and hundreds of other brands. • Optimized Node.js services for high-traffic, on-premise systems with high availability, zero-downtime deployments, and tight performance constraints. • Worked on a migration plan from PHP + React to Next.js, mentored frontend-focused enginee

I was brought in to support the adoption of modern web development practices within a team hesitant to move away from their legacy tech stack and workflow. I facilitated a shift from a build-and-handover delivery model toward projects requiring long-term maintainability. Introduced unit and end-to-end testing, gitflow, linting, type checking, established processes for reviewing and testing UI components.

Following a group-wide restructuring, I was offered a remote position to help establish new mobile-first front-end teams in the group's Budapest office. • Hiring and training new developers to work on the company's live streaming platform that served millions of daily visitors. • Developed a fully mobile browser-based video call front-end with real-time, bidirectional audio and video using early WebRTC technology, when cross-browser support and stability were still major challenges. • Created a browser-bas

Developed SaaS for music festival organizers and a Messenger chatbot for festival goers. The platform was tested live at major Hungarian music festivals, but deployment was paused due to the COVID-19 pandemic.

Transferred to Amsterdam after Docler suspended its Los Angeles operations. Helped establishing the Amsterdam office with the goal to attract and hire top engineering talent. • Defined and gained approval for a strangler-fig migration from Backbone.js to React, then coordinated its incremental rollout across multiple teams. • Was being on-call for the company's primary revenue-generating platform, responding to and resolving production incidents.

Transferred from Luxembourg to Los Angeles to support Docler's US operations, and the company's vision to build mainstream live streaming products based on lessons learned from monetizing adult content. Worked on several innovative products: Docler Music (a live platform for musicians), Streamago (similar to what TikTok Live would later become), Oranum (streaming platform for fortune tellers), and Stitch (a mobile app that anticipated Instagram Stories).

Following a company restructuring, I was transferred from Budapest to Luxembourg to continue my work on OTT and mobile platforms. • Developed low-latency live stream players for mobile browsers and smart TV platforms such as Samsung Tizen and LG webOS. • Implemented fallback streaming techniques like continuous JPEG feeds, WebSocket and long polling-based image delivery. • Optimized performance for embedded platforms with low-end CPUs and limited memory, working within tight rendering and execution budgets

Joined Docler's alternative platform team in Budapest, working on early-stage development of browser-based video solutions for mobile and smart TV platforms. Docler Holding was a pioneer in online live streaming and owned one of the first and most visited adult live streaming platforms. • Worked closely with video and backend teams to align front-end efforts with media delivery formats. • Developed creative workarounds to enable live video playback on mobile and OTT devices that lacked support for Flash or

Built custom Drupal and WordPress websites for clients referred by Hungarian software consultancies, who outsourced projects that were too small for their scale. • Provided clients with hosting and domain management through my own cPanel-based setup, handling deployments, domain configuration, and MySQL database management. • Proposed and developed a custom browser automation tool for scheduling Facebook page posts, using direct browser interaction before tools such as Puppeteer existed. • Built a 3D pers
