Overview
APIs are products in their own right: partners, mobile apps and internal teams depend on them being consistent, secure, fast and stable. We design APIs contract-first, implement them with robust authentication, validation, rate limiting and versioning, and ship them with documentation, SDKs and sandboxes. The result is an API layer that accelerates everyone who builds on it.
Common use cases
- Public developer APIAPIs for customers and partners to integrate with your platform.
- Mobile backend APIEfficient APIs tailored for mobile clients.
- Partner integration APISecure B2B data exchange.
- Internal platform APIShared services consumed across teams.
Quick answers
API Development at a glance
The essentials in brief. Every project is scoped individually — ask us for specifics.
- What is API development?
- Design and build secure, well-documented APIs that power your apps, partners and integrations — REST, GraphQL and real-time.
- Who is it for?
- Typically startups building a first product, scale-ups extending a platform, and enterprises replacing or modernising internal software.
- What does Shivacha provide?
- Contract-first design
- Security
- Performance
- Versioning
- Documentation & SDKs
- Monitoring
- Which technologies are used?
- React, Next.js, TypeScript, Node.js, Python, Flutter — chosen to fit your stack and constraints.
- How does the process work?
- Technical discovery → Architecture & design system → Parallel frontend and backend → Quality gates → Release and monitor.
- What affects the cost?
- Number of user roles and core workflows
- Platforms (web, iOS, Android)
- Third-party integrations
- Design depth and accessibility targets
- Data migration from existing systems
- Performance, scale and uptime requirements
- How long does it take?
- An MVP typically takes 8–14 weeks; larger platforms are delivered in phases with a usable release every few weeks.

Architecture
Engineered right from day one
The layers we typically design for web, mobile & full-stack engineering, adapted to your stack and partners.
- Performance budgetsCore Web Vitals and app start-time targets enforced in CI.
- AccessibilityWCAG-aligned components, keyboard navigation and screen-reader testing.
- Native vs cross-platformChosen per product based on performance, device features and team.
- API designConsistent, versioned, documented APIs that other teams can build on.
Delivery
How an engagement runs
- 1
Technical discovery
Requirements, platforms, integrations and non-functional targets.
- 2
Architecture & design system
Component library, API contracts and data model.
- 3
Parallel frontend and backend
Contract-first development so teams move independently.
- 4
Quality gates
Automated tests, Lighthouse and accessibility checks in CI.
- 5
Release and monitor
Staged releases, crash reporting and real-user monitoring.
Security
Security built into delivery
Controls we apply by default on this kind of work — not a separate phase at the end.
Secure SDLC
Code review, dependency scanning and secrets kept out of source control.
Authentication
Proven identity providers, MFA and least-privilege roles.
OWASP coverage
Protection against common web and API vulnerabilities, verified in testing.
Backups & recovery
Automated backups with tested restore procedures.

Learn moreReact vs Next.js: what's the difference and which should you build on?
React is a UI library; Next.js is a framework built on it. When a plain React single-page app is enough, and when server rendering, routing and SEO make Next.js the better choice.

Frequently asked questions
Do you build developer portals?
Yes — documentation sites with interactive references, getting-started guides, sandbox keys and change logs.
How do you handle breaking changes?
Through versioning, additive changes by default, deprecation notices and usage monitoring before removing old versions.
Native or cross-platform mobile?
Cross-platform frameworks such as Flutter and React Native suit most business apps and reduce cost. Native Swift and Kotlin are better for heavy device integration, advanced graphics or platform-specific experiences. We recommend per project.
Do you handle app store submission?
Yes — builds, signing, store listings, review guidance and release automation for both Apple App Store and Google Play.
