Custom software development in
New York City
Mejix is a senior software consultancy serving New York City. On-the-ground in Chelsea, Manhattan. We design, build, and modernise products for ambitious teams — fast, focused, and accountable.
What we build for New York teams
Custom software, built to ship
Product strategy, engineering, and platform work for ambitious teams — delivered by senior engineers, on your timezone.
Product & MVP development
Take a product from sketch to revenue: discovery, design, and full-stack engineering with a senior team.
Platform & SaaS engineering
Multi-tenant SaaS, billing, RBAC, observability, and SOC-2-ready architecture — built to scale past Series A.
Legacy modernisation
Strangle-fig migrations off legacy stacks (PHP, .NET, monoliths) into modern TypeScript / Node / cloud services.
Cloud, DevOps & data
AWS, GCP, Azure, Vercel, Supabase — production-grade infrastructure, CI/CD, and data pipelines without the platform-team headcount.
Integrations & APIs
ERPs, CRMs, payments, identity, EDI, and AI APIs — wired up, documented, and monitored.
Embedded staff augmentation
Senior engineers embedded into your team for 3+ months when you need velocity without the hiring overhead.
