Cloud Software Built to Scale With You
We design and build multi-tenant SaaS platforms and cloud infrastructure — from your first customer to your thousandth, without a rewrite.
What We Build
SaaS & Cloud Services
From first prototype to production infrastructure that holds up under real traffic.
SaaS Platform Development
Multi-tenant SaaS applications built from the ground up — user management, billing, role-based access, and tenant isolation done right the first time.
Cloud Architecture & Migration
Design and migrate infrastructure on AWS, GCP, or Azure — containerized services, managed databases, and infrastructure as code.
API & Microservices
REST and GraphQL APIs, event-driven microservices, and message queues built to handle real production load.
Database Architecture
Schema design, query optimization, and scaling strategies for Postgres, MongoDB, and Redis — built for your actual access patterns.
CI/CD & DevOps
Automated deployment pipelines, staging environments, and monitoring — so shipping is routine, not risky.
Billing & Subscriptions
Stripe and Paddle integrations for subscription billing, usage-based pricing, dunning, and revenue recognition.
Our Stack
Technology We Master
Battle-tested tools chosen for reliability, scalability, and long-term maintainability.
Proof of Work
Platforms We've Shipped
How We Work
Our SaaS Build Process
Architecture & Scoping
Data model, tenancy strategy, and infrastructure plan mapped out before a single line of code.
Build & Iterate
Sprint-based development with staging environments and regular demos — you see progress every two weeks.
Load Testing & Hardening
We test under realistic load, fix bottlenecks, and harden security before launch — not after.
Launch & Scale
Production deployment, monitoring dashboards, and a support retainer to scale with your growth.
Why SJ Dev Technologies
Engineers Who Think About Scale.
We don't just make it work for a demo — we ask what happens at 10x the users, what breaks first, and what it costs to run. You get infrastructure decisions made with your growth in mind, not just your launch date.
Built for Multi-Tenancy
We don't bolt tenant isolation on after launch — it's part of the schema and architecture decisions from day one.
Infrastructure as Code
Every environment is reproducible from a Terraform config, not a runbook someone forgot to update.
Observability First
Logging, error tracking, and metrics are wired in before launch, not added after the first outage.
Cost-Conscious Scaling
We size infrastructure to your actual traffic, not a worst-case guess that triples your cloud bill.
Full Source Ownership
Your codebase, your infrastructure configs, your cloud account — nothing runs on infrastructure you don't control.
Post-Launch Support
Month-to-month engineering retainers for monitoring, scaling, and feature work after launch.
