Acerca de este Servicio

I build lightweight browser apps optimized for one practical task, such as a calculator, checklist or input tool. I use AI to assist development and review the result.


The $80 package includes one responsive screen, one core feature, HTML/CSS/JavaScript source, run instructions, 3-day delivery and one revision.


We target around 1 MB (1,000,000 bytes): the combined uncompressed runtime files, including code, images, icons and fonts. Documentation and development-only files are excluded. I avoid unnecessary dependencies and provide a file-size breakdown at delivery. External CDNs are not used to hide assets from the count.


Before ordering, we confirm the feature, required assets, target browser and size-target feasibility through Fiverr. File size alone does not guarantee speed or memory use.


Reproducible errors in the agreed environment are fixed for 7 days after delivery, separately from the revision.


Native Android apps, login, payments, servers, databases, external APIs and hosting need a separate quote. All work is remote; communication and delivery stay on Fiverr, primarily in written English.
