Custom Software Development
We design and develop custom software for your specific needs, with no compromise on quality or scalability. We analyse requirements, define the architecture, develop in weekly sprints with continuous demos, integrate with existing systems, and guarantee complete technical documentation and post-launch support.
What we deliver
- System architecture design: monolithic, microservices or serverless based on expected load
- Backend development with REST and GraphQL APIs, documented via OpenAPI/Swagger
- Web frontend using modern frameworks (React, Vue, Angular) with SSR/SSG rendering
- Integration with ERP, CRM and third-party platforms via native connectors or custom middleware
- CI/CD pipelines on GitHub Actions, GitLab CI or Azure DevOps with automated test gates
- Test coverage strategy: unit, integration and E2E with coverage thresholds defined upfront
- Legacy application migration and refactoring toward maintainable, documented stacks
- Structured technical documentation: ADRs, C4 diagrams, operational runbooks
When you need it
Internal tooling that has outgrown off-the-shelf software
The business runs on a generic ERP or spreadsheets, but internal processes are too specific for standard solutions. Manual workarounds pile up and create errors. You need software built around your actual workflow, not the other way around.
Digital agency that needs to subcontract development without losing ownership
You've sold a complex project but don't have the internal tech capacity to deliver it. You need a white-label partner who respects the deliverables agreed with your client, meets deadlines, and doesn't create technical dependencies that are hard to untangle later.
Startup or SMB that needs a production-ready MVP on a fixed timeline
Budget is set, deadline is real. You can't afford to redo the architecture halfway through. You need a team that makes defensible technical decisions from day one and delivers something solid — not a prototype that breaks under real-world conditions.
Existing application that can't handle business growth
The software you built two years ago handled 50 users fine. Now you have 500 and performance degrades under load. You need an honest technical assessment and a prioritized refactoring plan — not a pitch to rewrite everything from scratch.
Frequently asked questions
How long does it take to have a working first version?
It depends on scope, but a core-functionality MVP is typically deliverable in 6-12 weeks. The estimate gets precise after a 1-2 day requirements analysis. Evviva provides a milestone-based roadmap with clear acceptance criteria before any contract is signed.
Who owns the code?
You do — from the first commit. The source code is delivered to a repository you control, with full history. There are no lock-in clauses on the code. You can hand it off to another team at any point without losing anything.
How do you handle requirement changes mid-project?
Changes are expected, not exceptions. Short sprints and a prioritized backlog mean every new request gets estimated and scheduled into the next cycle. Nothing gets absorbed silently — every change has a declared impact on timeline or scope, so you can make an informed decision.
What happens if critical bugs surface after go-live?
The contract includes a post-launch warranty period — typically 30-90 days — during which reproducible bugs attributable to the development work are fixed at no extra cost. Acceptance criteria are defined before development starts, not after delivery.
Can our internal team take over development after handoff?
Yes, and we plan for it from the start if that's the goal. We use standard, well-documented stacks, avoid obscure dependencies, and deliver technical documentation that lets an external team pick up the project without having to reconstruct context from scratch.
