Our Stack
Battle-Tested Technologies
We use the right tool for the job — proven technologies with strong ecosystems, not chasing hype.
What We Build
Full Backend Coverage
From a single microservice to a distributed system — we architect, build, and maintain it all.
REST & GraphQL APIs
Clean, versioned, well-documented APIs built to REST best practices or GraphQL schemas — designed for mobile, web, and third-party consumers.
Database Design
Relational and NoSQL database architecture optimised for query performance, integrity, and scale — from schema design to indexing strategies.
Auth & Security
Enterprise-grade authentication flows, role-based access control, and security hardening to keep your data and users safe.
Microservices
Event-driven microservice architectures with message queues, service discovery, and resilient inter-service communication patterns.
Real-time Systems
WebSocket servers, push notifications, and streaming APIs for live dashboards, chat, collaborative tools, and IoT data pipelines.
Third-party Integrations
Seamlessly connect payments, CRMs, ERPs, and any SaaS tool via robust webhook handling and idempotent API consumers.
Why Vewnex
Backend That
Never Lets You Down
We've built backends that handle millions of requests — we know where systems fail under load, how security holes get exploited, and what makes a codebase a nightmare to maintain. We build none of those things.
API-first by design
Every system is built to be consumed — clean contracts, versioning, and documentation from day one.
Security is non-optional
Auth, rate limiting, input validation, and OWASP hardening are built in, never bolted on.
Scale without rewrites
We design for 10× your current traffic so you never need an emergency refactor at 3 AM.
Full handover & docs
Comprehensive API docs, architecture diagrams, and runbooks so your team owns the system completely.
How We Work
From Brief to Production
A structured process that ships clean, tested code fast — without skipping architecture or documentation.
Discover
We map your data flows, existing systems, and integration requirements to design the right architecture from the start.
Architect
Schema design, API contracts, auth model, and infrastructure plan — agreed and documented before any code is written.
Build
Clean, tested, documented code shipped in sprints. Every endpoint comes with automated tests and Swagger docs.
Monitor
APM dashboards, error tracking, and monthly performance reviews to keep your backend fast and reliable.
Investment
Backend Packages
Fixed-scope projects or ongoing retainer — choose what fits your stage.
