Six services, one team — web, mobile, AI, DevOps, SaaS and UI/UX, built and owned end-to-end. No handoffs between departments, no gaps between design and code.
Stack46 builds fast, search-ready web applications on Next.js, React and TypeScript — the same stack that powers the FourSix46 ecosystem. From marketing sites to complex platforms, engineered to perform, rank, and scale.
Stack46 builds cross-platform apps that feel native on iOS and Android, using React Native, Flutter and Expo. We handle design, development, store submission and ongoing maintenance — backed by the same full-stack backend that powers the FourSix46 ecosystem.
Stack46 builds practical AI and machine-learning features into production software — LLM-powered tools, semantic search, recommendation and automation — engineered in Python on AWS, Google Cloud and Azure. Real features shipped into real products, not proof-of-concept demos.
Stack46 builds and runs cloud infrastructure that stays fast, secure and online — CI/CD pipelines, containerised deployments and multi-cloud architecture across AWS, Google Cloud and Azure. The same infrastructure discipline that keeps the FourSix46 ecosystem running in production.
Stack46 builds multi-tenant SaaS platforms from first MVP to production scale — auth, billing, dashboards and APIs on Next.js, Node.js and PostgreSQL. The same full-stack engineering that built the FourSix46 ecosystem's own platforms, applied to yours.
Stack46 designs interfaces and product experiences that are clean, accessible and built to convert — from research and wireframes to polished, production-ready UI. Design and engineering under one roof, so what's designed is exactly what ships.
The largest platform in the FourSix46 ecosystem — digital infrastructure for the global film industry, launching Phase 1 in India.
The founder platform behind FourSix46 — Dinesh Koyyalamudi's personal site, live and built on the same production stack as the ecosystem it anchors.
The digital home of the FourSix46 ecosystem — the entity, ventures and legal identity that every Stack46 build answers to, live and content-managed in-house.
A living registry where every rescued street dog becomes a permanent, followable record — landing page live, full platform in active development.
A live UK courier and logistics platform — an inherited codebase taken over, enhanced, and re-deployed on the ecosystem's cloud infrastructure by Stack46.

Building since
We learn your goals, users and constraints — then map the fastest path to a product that lasts.
Interface and flows designed and prototyped, so the idea is validated before a line of production code is written.
Senior engineers build on production-grade foundations — clean architecture, real documentation, the same standard as our own products.
We ship, monitor, and iterate — engineered to stay fast, findable, and stable as you grow.
Proposal in 48 hours. No commitment. Just a conversation about your product.
