WHEN THIS HELPS
Where this service fits.
Your backend needs to scale past its current architecture
An existing .NET system is hitting limits that need real architectural work, not just more servers.
You need a business workflow automated end to end
A manual or semi-manual process needs to become a reliable, production backend service.
Your API layer needs a senior owner
REST APIs powering mobile, web or partner integrations need someone who can own design and performance, not just endpoints.
What WALTIQ can deliver
- REST API design and implementation in .NET / C#
- SQL schema design, query optimization and Entity Framework data access
- Service boundaries and workflow/business logic automation
- Third-party and internal system integration
- Performance tuning, maintenance and modernization of existing backends

FAQ
Common questions
Can you work within an existing .NET codebase?
Yes — reviewing and optimizing an existing backend, including SQL procedures and service boundaries, is core to how this work is approached.
Do you design REST APIs from scratch?
Yes, for new products and for adding new capabilities to existing systems.
Can this work happen alongside our internal team?
Yes — backend engagements are commonly delivered in collaboration with an existing internal engineering team, not as an isolated black box.
Have a project that fits this?
