Linkavista

01 / The problem

Advertisers want sponsored content placements and publishers want to earn money from their websites. Both need a place they can trust, where sites from many countries and languages can be compared and checked for authenticity before anyone pays. Payments also have to work without leaving either side carrying the risk.

02 / What I built

I worked on Linkavista as a freelance full-stack developer, shipping major features on the Laravel platform and tightening its security. On the marketplace side I built the workflows between publishers and advertisers and the escrow payments, which run on Stripe and Qonto. Google Search Console is wired in so the platform can verify who owns a site and pull its data. I also wrote an in-house SEO scoring engine that ranks and compares sites, then added AI image generation with Flux models running on in-house GPU infrastructure. On security I hardened authentication and the payment flows and improved how user data is protected.

03 / Impact

Linkavista runs at international scale. The platform publicly lists more than 5,000 publishers and around 96,000 sites across 40+ countries and 26 languages. The features I shipped sit at the core of the marketplace, from escrow and site verification to SEO scoring and security. My own contribution comes to 112 commits, with about 45,500 lines added and 7,650 removed.
