The independent practice of Igor Tosic.
Focused on the hard parts of visual web software: document and PDF annotation, canvas-based interfaces, and geospatial applications that stay fast over very large datasets.
Most web work is forms and dashboards, and most developers are good at it. Far fewer have built an annotation engine that engineers depend on daily inside a major energy company, or migrated a national-scale mapping application between GIS stacks. That's the work this practice takes on.
Expertise & Services
-
Annotation and markup tools
Drawing, measurement and markup over PDFs, drawings and technical documents, built on HTML5 Canvas platforms.
-
Map and geospatial interfaces
Interactive maps that stay responsive over large datasets, migration between GIS stacks (ArcGIS, OpenLayers, MapLibre), and performance work on maps that have slowed as data grew.
-
Complete web applications
When the visual layer is part of a larger product, I build frontend and backend systems natively in Python/Django, Node, or Java/Spring.
Custom CRM Solutions
