Trusted by founders and engineering leaders
Read how our pragmatic engineering approach resolved complex roadblocks across diverse systems.
“Our tracking dashboard was unusable on mobile 3G connections. JoinAffix refactored our state management and bundle payload, cutting initial JavaScript by 65%.”
“We generated our cross-border remittance MVP using Cursor and Supabase, but our JWT auth broke right before regulator demo day. JoinAffix joined our emergency channel in 30 minutes, sanitized our API boundaries, and deployed a rock-solid Next.js app in 5 days with zero security red flags.”
“Handling bilingual Arabic/English RTL layouts with real-time telematics dispatch is notoriously difficult. JoinAffix delivered a flawless Next.js system with sub-100ms Redis updates across our 400 delivery trucks.”
“JoinAffix replaced our brittle 8-second refresh dispatch tool with an instantaneous WebSocket-driven Next.js application. Our dispatchers haven't experienced a single race condition since launch, and our load throughput jumped over 4x.”
“Rendering 100,000 spatial parcel boundaries smoothly in a web browser seemed impossible until JoinAffix engineered custom vector tile pipelines and PostGIS indexes. It saves each of our analysts over 10 hours every week.”
“We needed a WebGL geospatial mapping viewer capable of rendering 50,000 polygon overlays without stuttering. JoinAffix engineered custom worker threads and canvas shaders that run at a locked 60 FPS.”
