What engineering leaders say about working with us
Direct feedback from founders, CTOs, and product executives.
“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 15 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.”
“Migrated our legacy WordPress news portal to Next.js in 3 weeks. PageSpeed went from 24 to 98 and our ad revenues doubled immediately.”
“Our staging environments were out of sync with production servers, causing failed deployments every week. JoinAffix automated our Docker CI/CD pipelines with GitHub Actions. Releases are now instant and zero-downtime.”
“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.”
