Engineering approach
One system,five layers.
Product, frontend, backend, data and infrastructure are designed together, not handed between vendors. This is how the layers relate.
Next.js · React · React Native
Experience
The interface people actually touch. Frontends that feel less like websites and more like native software — fast, interactive and considered.
- Server-rendered (SSR)
- iOS & Android from one codebase
Node.js · Python
Application
Typed APIs and services that move and shape the data — the central nervous system of your product, executing your business rules.
- REST / GraphQL / gRPC
- Typed validation, automated tests
PostgreSQL
Data
Structured, secure storage — your single source of truth. Schemas and architecture designed for scale, resilience and fast queries.
- Relational / distributed design
- TLS-encrypted in transit
AWS · Oracle Cloud · Docker
Infrastructure
Containerised deployments, reverse-proxy and TLS setup, and automated CI/CD pipelines on managed cloud servers.
- Docker & GitHub Actions CI/CD
- Nginx, TLS/SSL, firewalling
LLM · WhatsApp · payment gateways · CRMs
AI & integrations
Cross-cutting by design: pragmatic LLM features and third-party integrations wired into the layers above, not bolted on beside them.
- Search, summarisation, extraction
- CRM, payment and ERP connectors
Company
Clean architecture,resilient infrastructure,practical delivery.
KelvionTech is a software development and technology solutions firm based in Ahmedabad, Gujarat. Our engineers, product designers, and cloud architects turn operational requirements into production-ready web platforms, mobile applications, and automated workflows. Beyond client engagements, we design and operate two SaaS products of our own — Jamanvar, a restaurant point-of-sale and kitchen display system, and Vartalaap, a WhatsApp-based ordering platform — so the standards we hold client work to are ones we run our own software against, every day.
Full-stack delivery
Design, frontend, backend, and DevOps handled by one dedicated team, not fragmented vendors.
Modern technology stacks
Next.js, React Native, Node.js, Python, and cloud-native infrastructure on AWS and Oracle Cloud.
