NewMatrytech AI Studio is live — build production-grade AI agents in weeks, not quarters.
— Web Application & SaaS Engineering

Full-stack web platforms built to scale from day one.

React, Next.js and Node.js applications with real-time features, multi-tenancy, Stripe billing and production-grade architecture. We build SaaS products that work for 10 users and for 10,000 — without a rewrite in between.

— What we build

Six capabilities. One production team.

Every web project is delivered with automated tests, CI/CD pipelines, staged deployments and monitoring wired in. Production-grade from the first commit — not bolted on at the end.

— 01

Full-stack Web Applications

React and Next.js frontends paired with Node.js or Python backends. Server-side rendering for SEO, client-side for interactivity, and edge functions where latency matters.

  • Next.js App Router, React 18
  • Server Actions + API routes
  • Edge middleware, ISR, streaming
— 02

Multi-tenant SaaS Platforms

Architecture that separates tenant data properly — not row-level tenant_id hacks. Stripe billing, usage metering, plan limits, customer dashboards and a superadmin panel included.

  • Schema-per-tenant or row isolation
  • Stripe / Paddle billing + webhooks
  • Usage metering, plan enforcement
— 03

Real-time Features

Live dashboards, collaborative editing, chat, notifications and event feeds. WebSockets, Server-Sent Events or Pusher depending on the use case — chosen for your scale, not ours.

  • WebSockets, SSE, Pusher / Ably
  • Optimistic UI, conflict resolution
  • Presence, typing indicators, feeds
— 04

Admin Panels & Back-office

Custom-built admin interfaces, not Retool or Airtable hacks. Data tables with bulk actions, export, real-time sync and role-based access — the tool your ops team actually wants to use.

  • Tanstack Table, server-side pagination
  • CSV / PDF export, bulk ops
  • RBAC, audit logs, impersonation
— 05

API-first & Headless Platforms

Backend APIs consumed by web, mobile and third-party clients. GraphQL for flexible query, REST for broad compatibility, event-driven for async workflows. Documented with OpenAPI from day one.

  • REST + GraphQL + WebSockets
  • OpenAPI spec + SDK generation
  • Event-driven: SQS, Kafka, Pub/Sub
— 06

Performance & SEO Engineering

Core Web Vitals optimisation, server-side rendering for SEO, CDN strategy and image pipelines. We inherit broken Lighthouse scores and fix them — measured before and after, not estimated.

  • Core Web Vitals: LCP, INP, CLS
  • Next.js ISR + CDN edge caching
  • Structured data, sitemap, meta

— How we work

From spec to production deploy.

No discovery theatre. No 4-week "kickoff sprint" before we write code. Fixed quote in 48 hours, working software by week two.

01

Discovery — Week 0

60-minute call covering user journeys, integrations and the one metric that defines success. Fixed quote in writing within 48 hours.

02

Architecture — Week 1

Data model, API contract, auth strategy, infrastructure diagram. Your sign-off before production code begins. No surprise rewrites later.

03

Build — Weeks 2–6

Two-week sprints, Friday demos, GitHub access from day one. CI/CD running from the first commit. You test on staging after every sprint.

04

Launch — Week 7+

Production deploy with monitoring, alerting and a runbook. Handover session with the engineer who built it. Retainer available or clean handover — your call.

— Why us

Architecture decisions that survive year two.

Most agencies optimise for shipping fast. We optimise for not having to rewrite in six months. The two goals are compatible — if you make the right choices in week one.

— 01 · Architecture-first, not framework-first

We pick the boring technology that won't embarrass you at 100k users.

We've inherited systems built with whatever was trendy in the year it was written. Postgres over MongoDB for transactional data. Server-side rendering where it matters. No premature microservices on a product with 200 users. The tech choices we make in week one are the ones you won't have to pay someone to undo in year two.

— 02 · Tests ship with the code, not after

CI blocks on test failure. Always. From the first sprint.

We don't treat testing as a handover checklist. Integration and end-to-end tests are written in the same sprint as the feature. Playwright for critical user flows. The CI pipeline blocks deployment on test failure from week one. You inherit a codebase with real coverage — not a coverage badge that counts string assertions.

— Proof in production

Fleet management dashboard for 50K+ operators.

One example from a larger portfolio of web platforms under our maintenance.

Real-time fleet dashboard used by Govt. of Karnataka and Renault across India.

A full-stack Next.js and Node.js platform with real-time telemetry, AI route planning, driver management, billing and multi-tenant fleet operator dashboards. Built from zero to 50,000+ active operators in three months.

— Frequently asked

Five questions every web buyer asks.

Anything missing — email Prakash directly, replies same day.

Do you build on WordPress or Webflow?
No. We build custom web applications with React and Next.js. If you need a marketing site or content-heavy landing pages, Webflow or a headless CMS is often the right call — and we'll tell you honestly. But if you're building an application with users, data, and business logic, a custom stack will serve you better.
How do you handle authentication?
We use Clerk for most greenfield projects — fast to integrate, good UX, handles social login, MFA and session management. For enterprise requirements (SAML, SCIM, custom identity providers) we integrate with Auth0 or implement a custom OAuth2 server. We never build auth from scratch unless there's a compelling reason.
Can you build SaaS with subscription billing?
Yes — it's a standard part of our SaaS engagements. Stripe integration including subscriptions, usage-based billing, invoices, trial periods, dunning and customer portal. We also handle Paddle for non-US SaaS (handles VAT automatically). The billing system ships with your app, not as a separate phase.
What happens when we reach scale?
We design for it from the start. Connection pooling (PgBouncer), Redis caching, queue-based background jobs (BullMQ), CDN for assets, horizontal scaling via containers. We don't build throwaway MVPs — if you come back in a year with 100x more users, we want the architecture to handle it without a rewrite.
Do you offer post-launch support?
Yes — a maintenance retainer of $1,500–3,000/month covers bug fixes, dependency updates, security patches and a feature iteration budget. Alternatively, we do a thorough handover and you take it forward internally. We write runbooks and document the deployment process either way.
