Technology stack

Modern Tools. Battle-Tested Choices.

We don't chase trends: we pick technologies with deep ecosystems, long support horizons and proven records in production. These 44 are what our own products and client projects run on today.

Backend

.NET 10 & ASP.NET Core

Our default for APIs, background workers and business platforms, on the current long-term-support release of .NET.

Entity Framework Core 10

Typed data access and migrations for PostgreSQL and SQL Server, so schema changes ship with the code that needs them.

SignalR

Real-time updates pushed to browsers and phones: live restaurant floors, ticket queues and dashboards without refreshing.

OpenID Connect & OAuth 2.0

Single sign-on across products with OpenIddict, plus JWT-secured APIs and two-step sign-in where a product needs it.

Background Jobs

Hangfire and .NET worker services for scheduled reports, reminders, imports and anything that should not keep a user waiting.

Node.js

Server-side JavaScript for Next.js sites, automation workers and integrations, on Node 24.

Python & FastAPI

Fast, typed Python APIs for data-heavy and AI-backed services, as used in our telematics and healthcare projects.

Frontend

React 19

The foundation of every web interface we ship, from admin consoles to customer portals.

Next.js 16

Server-rendered, search-friendly websites and web apps, including our own product sites.

TypeScript

Type-checked code across web, mobile and Node projects, so whole classes of bugs are caught before release.

Tailwind CSS 4

A consistent design system in code, with light and dark themes that stay in step across a product.

Vite 8

Fast builds for single-page business apps such as field-tracking and ticketing dashboards.

TanStack Query

Server data cached and kept fresh in the browser, so screens load quickly and stay in sync.

Mobile

React Native

One codebase for Android and iOS apps, sharing types and logic with the web.

Expo SDK 57 & EAS

Native builds, over-the-air updates and device features such as camera, location and secure storage.

Push Notifications

Expo push and Firebase Cloud Messaging for approvals, alerts and reminders that reach the phone.

Maps & Location

Google Maps and Leaflet with background location for field teams, geofences and live tracking.

Database

PostgreSQL 17

Our default database for new products, with pgvector where search needs to understand meaning, not just keywords.

SQL Server

The backbone of many ERP, HR and point-of-sale systems we build and support.

MongoDB

Flexible document storage for apps whose records vary in shape, such as our godown (warehouse) inventory app.

Redis

Caching and real-time message fan-out for busy, multi-server applications.

Cloud

Microsoft Azure

Cloud servers, Windows desktops and business application hosting for clients who run on Microsoft.

AWS

Cloud servers, S3 storage and off-site backups for applications and data.

Cloudflare

DNS, proxying, bot protection with Turnstile, and edge functions with Workers.

Vercel

Hosting for Next.js and front-end sites, including aptivix.in.

Linux & Windows Servers

Managed servers running our applications as systemd or Windows services behind Nginx.

DevOps

Docker

Containerised services, so an environment runs the same on a developer laptop as in production.

GitHub Actions

Automated builds, tests and deployments on every change.

Kubernetes

Container orchestration for client workloads that need to scale across machines.

Nginx

Reverse proxy and TLS in front of our APIs and web apps.

Automated Testing

Playwright for end-to-end browser tests and Vitest for unit tests, run in CI before a release.

Logging & Tracing

Structured logs with Serilog and traces with OpenTelemetry, so problems can be followed across services.

Data & AI

Claude (Anthropic)

Large language models behind assistants, document understanding and automation in our CRM, help desk and voice products.

OpenAI

GPT models for drafting, summarising and extracting data, chosen per task alongside Claude.

Google Gemini

Multimodal models for apps that work with images, audio and live conversation.

Sarvam AI

Speech-to-text and text-to-speech for Indian languages in voice applications.

ONNX Runtime

Machine-learning models run on our own servers, such as face matching for attendance.

Dashboards and governed reports that put live KPIs in front of decision-makers.

Integrations

WhatsApp Cloud API

Alerts, verification codes and notifications sent on WhatsApp from our products.

Razorpay & UPI

Online payments and UPI collection for Indian businesses.
