Our Tech Stack — Every Choice Made for a Reason.
We don't follow trends. Every technology on this page is here because it's the right tool for a specific problem — proven across 50+ products shipped for clients in US, UK, and Australia.
Flutter
One codebase ships to iOS and Android. Near-native performance. We've shipped ClinikPe (12K+ DAU, 4.8★) and 20+ other apps on Flutter.
React Native
Best choice when your web team is already deep in React. Shares business logic with your web app and reduces total engineering overhead.
Swift & Kotlin
For apps that need deep platform access — ARKit, HealthKit, background processing, or hardware integrations where cross-platform frameworks hit limits.
React
Our go-to for complex dashboards, admin panels, and SPAs. Component architecture scales well. TypeScript + TanStack Query for production-grade state.
Next.js
When SEO matters — marketplaces, SaaS marketing sites, content platforms. SSR, App Router, and edge functions. Used for Delinow's marketplace.
WordPress
When the client team needs to own their content without developers. We build fast, secure custom-theme WP sites — not bloated page builders.
Node.js
Our default API layer. Non-blocking I/O handles mobile API patterns perfectly. Express for pragmatic builds, Fastify when we need sub-10ms response times.
Python
The only sensible choice when your product touches AI, ML, or data pipelines. FastAPI for async APIs, LangChain for LLM chains, pgvector for embeddings.
Laravel
Batteries-included PHP framework for complex enterprise web apps. Eloquent ORM, queues, broadcasting, and a large ecosystem — production-proven at scale.
Shopify
Our preferred eCommerce platform. Custom theme development, headless Shopify via Hydrogen, plus app integrations. ₹30K/mo+ retainer clients run on Shopify.
WooCommerce
For India-based sellers who need full control, Razorpay/PayU integrations, and lower transaction fees vs Shopify. Built on WordPress — clients own everything.
AWS
Our default cloud for production workloads at scale. EC2, ECS, RDS, S3, CloudFront — we architect for reliability, cost-efficiency, and compliance.
Firebase
The fastest way to ship a working MVP with auth, real-time database, and push notifications in days, not weeks. We plan the migration path to SQL from day one.
OpenAI / GPT-4o
GPT-4o for intelligent features — document analysis, chatbots, recommendation engines, and content generation. Paired with Python/FastAPI and pgvector.
Which Stack Is Right for You?
Quick reference — the short answer to the question we get asked most.
| If you're building… | We recommend |
|---|---|
| A mobile app (iOS + Android) | Flutter + Node.js |
| A SaaS dashboard / web app | React + Node.js + PostgreSQL |
| A marketplace or SEO site | Next.js + PostgreSQL |
| An AI-powered product | React + Python (FastAPI) + GPT-4o |
| An eCommerce store | Shopify (or WooCommerce for India) |
| A fast MVP (4–8 weeks) | Flutter + Firebase |
| A content / marketing site | WordPress (custom theme) |
We Choose Tech That Solves Your Problem — Not What's Trending.
Every recommendation on this page comes from real production experience. ClinikPe runs on Flutter + Node.js. PagarAI runs on React + GPT-4o + Python. Delinow runs on Next.js. We've seen what breaks at scale and what doesn't.
When you ask us what stack to use, we give you a straight answer backed by data — not a list of options that leaves you guessing.
Production-Tested
Every tech on this page has shipped in production. No experimental choices for your product.
Right Tool, Right Job
We don't push a single stack on every project. Mobile apps, AI products, and eCommerce all have different needs.
Migration-Ready
When we use Firebase or a quick MVP stack, we design the data layer for migration before writing line one.
India-Optimised
Payment gateways, OTP auth, low-bandwidth performance — our stacks account for Indian infrastructure realities.

Everything You Need to Know
Explore key insights about the technologies we use to deliver fast, reliable, and future-ready solutions.
Flutter is our default for cross-platform iOS and Android — one codebase, near-native performance, and ~40% cheaper than building separate native apps. We use React Native when the client team already has strong JavaScript expertise. Native Swift (iOS) and Kotlin (Android) are reserved for apps needing deep hardware integration — ARKit, HealthKit, or complex background processing.
Both, but for different reasons. React is our choice for complex dashboards and SPAs where server-side rendering doesn’t matter — SaaS admin panels, internal tools. Next.js is used when SEO is a priority — marketplaces, content platforms, landing pages that need to rank. Next.js App Router + Vercel is the fastest path to a performant, SEO-friendly product.
Node.js (Express or Fastify) for most projects — especially where the frontend team is JS-heavy and we want one language across the stack. Python with FastAPI or Django for AI/ML products, data-heavy applications, or anything touching LLMs. Laravel for enterprise-grade PHP applications where the client has an existing PHP codebase or team.
Shopify for international-facing stores, premium UX requirements, or headless setups with Hydrogen. It’s faster to launch on and has a stronger ecosystem for performance marketing integrations (Meta, Google, Klaviyo). WooCommerce for India-first stores that need Razorpay/PayU/COD flows, lower transaction fees, or full data ownership. Also better if the store is tightly integrated with an existing WordPress content site.
Yes. We inherit and extend existing codebases regularly — React frontends with legacy backends, Shopify stores that need custom app development, or WordPress sites getting a headless upgrade. We conduct a brief technical audit first to understand the architecture, then scope the work clearly before writing a line of code.
