Tech We Use

Frameworks & Technologies

N
Next.js 15
Top Pick 2026

App Router, React Server Components, streaming, ISR, and edge deployment. Best for SEO-critical apps, e-commerce, and content-heavy platforms.

Django
Battle-Tested

Django REST Framework for APIs, Django ORM for complex data queries. Excellent for data-driven apps, admin panels, and enterprise backends needing security and compliance.

Node.js / Fastify
High Throughput

Ultra-fast APIs for real-time applications, WebSockets, event-driven architectures, and microservices with high request concurrency.

FastAPI
Python · Fast

Async Python API framework with automatic OpenAPI docs, type validation, and excellent performance. Ideal for ML-integrated backends and data APIs.

React SPA
App Dashboards

Rich interactive dashboards, internal tools, and admin panels. React with TypeScript, Zustand/React Query for state, and Vite for fast builds.

PostgreSQL + Redis
Data Layer

Relational data with PostgreSQL, caching and pub/sub with Redis, and full-text search. Designed for ACID compliance, complex queries, and scaling reads with replicas.

We build with Next.js 15 (App Router), React, and TypeScript for the frontend, and Django REST Framework, FastAPI, or Node.js/Fastify for the backend. We choose the stack based on your SEO requirements, performance targets, and team's existing skills.
Yes. We architect websites with server-side rendering (SSR), static generation (SSG), structured data markup, Core Web Vitals optimization, semantic HTML5, and proper canonical/meta tag management. We target 95+ Lighthouse scores on all pages.
A marketing website takes 2–4 weeks. A web application with auth, database, and dashboards takes 6–12 weeks. Complex platforms with API integrations, real-time features, and advanced workflows take 12–24 weeks. We provide accurate estimates after a free scoping call.
Yes. We migrate legacy PHP, WordPress, and outdated React codebases to modern Next.js or Django architectures. We run parallel environments and phase migrations to eliminate downtime risk and validate functionality incrementally.
Yes. We handle cloud deployment on AWS, GCP, or Vercel, with CI/CD pipelines, staging environments, SSL, CDN configuration, and monitoring setup. We document everything so your team can operate it independently.
