Event-Driven Rules
Our Engineering Process
A transparent, sprint-driven methodology that takes your software from architecture blueprint to production deployment.
Discovery & Scoping
We map your business rules, user roles, data models, and third-party integrations into a concrete technical specification and fixed milestone roadmap.
UI/UX & Architecture
Interactive wireframes, database schemas, and API contracts are designed upfront so you experience the workflow before production code is written.
Agile Sprint Delivery
We ship working software in iterative sprints to a live staging environment with weekly demos, automated tests, and direct developer communication.
QA, Launch & SLA
End-to-end security auditing, load testing, zero-downtime cloud deployment, team training, and ongoing SLA maintenance.
Why Partner With Sputnik Devs
We don't just write code — we own commercial SaaS platforms in production and bring that same operational rigor to your software.
Production-Grade Architecture
Clean, modular codebases built on SOLID principles, strict type safety, and automated database migrations.
Predictable Sprint Delivery
Milestone-driven roadmaps with live staging previews so you see measurable progress every single week.
Direct Engineer Access
Work directly with the senior engineers architecting your system — zero middlemen or communication bottlenecks.
Security & POPIA by Design
Role-based access control, encrypted data at rest and in transit, HMAC webhook verification, and full audit logging.
Built for Scale
Multi-tenant database indexing, Redis caching, and containerized deployments ready to scale from 100 to 100,000+ users.
Long-Term SLA Support
Dedicated post-launch maintenance, proactive server monitoring, security patching, and continuous feature evolution.
