Can you build on our existing codebase or must it be fresh?

We frequently step into existing codebases. We perform an initial technical audit to identify risks before recommending whether to refactor incrementally or rebuild critical components.

How do you handle project communication?

Direct engineering communication via Slack or Discord, weekly demo video check-ins, transparent GitHub PR reviews, and sprint boards.

FULL-STACK PRODUCT DEVELOPMENTSenior Lead Active

Product-grade web applications engineered for scalability and long-term maintainability.

We don't build disposable brochure sites. We design, architect, and ship production web software with clean codebases, tested integrations, and resilient architecture.

The Core Technical Bottleneck We SolveHigh Business Impact

Most businesses outgrow cookie-cutter website templates and low-code builders when they require custom workflows, multi-tenant databases, complex authorization roles, high-performance querying, and seamless API integrations. Without senior engineering, technical debt compounds fast, slowing down roadmap velocity.

All Testimonials

Web Engineering

Built bilingual RTL Next.js telematics platform for 400+ vehicles.

“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.”

Farhan Siddiqui

VP of Engineering, Sahab Logistics

Web Engineering

Replaced our brittle dispatch tool with an instantaneous Next.js platform.

“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.”

Marcus Vance

VP of Engineering, FreightCore Logistics

Web Engineering

Engineered high-performance geospatial analytics saving 10+ hours per week.

“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.”

Sarah Jenkins
