Web & App Development
Custom Web & App Development That Scales With Your Business
We engineer production-grade Next.js applications, React Native mobile apps, and full-stack SaaS platforms for companies that take their product seriously. Not template resellers — real engineers who own the outcome.
Based in Kolkata. In-house team. No subcontracting. Transparent pricing.
What We Build
Three Services. One Expert Team.
Whether you need a blazing-fast marketing site, a cross-platform mobile app, or a multi-tenant SaaS platform, we have the architecture and delivery experience to get it right.
Next.js Development
Production-grade React for marketing sites, dashboards, and enterprise apps
We build server-rendered, App Router–powered Next.js applications that score 95+ on Core Web Vitals by default. From a two-week landing page sprint to a multi-year enterprise portal, we ship clean, type-safe code your team will actually enjoy maintaining.
- SSR & SSG for SEO: Server-rendered and statically generated pages mean your content is indexed in full — no client-side rendering penalty.
- App Router architecture: React Server Components, nested layouts, streaming suspense boundaries, and parallel data fetching — used properly, not cargo-culted.
- TypeScript-first by default: Every new project starts typed end-to-end; we retrofit types to legacy code as part of our migration engagements.
- Vercel & edge deployments: Instant preview URLs for every PR, global CDN edge functions, and zero-downtime production deploys out of the box.
- Integrated CMS & headless: We connect Contentful, Sanity, or Strapi for content teams while keeping the dev experience clean and type-safe.
Common use cases
React Native Apps
One codebase, native performance — iOS and Android shipped together
Building two separate native apps doubles your burn rate without doubling value. Our React Native teams ship a single high-quality codebase that compiles to true native components on both platforms — then we own the release pipelines through App Store Connect and Google Play so you don't have to.
- Native modules where it matters: Biometrics, push notifications, BLE, camera — we drop down to native Kotlin/Swift when JavaScript isn't enough.
- Expo & bare workflows: Expo Go for fast iterations in early product stages; bare workflow for apps that need custom native modules in production.
- Offline-first architecture: Local SQLite or WatermelonDB with sync strategies — your app works on a train through a tunnel.
- Deep linking & push notifications: Universal links, Firebase Cloud Messaging, and in-app notification centres configured and maintained.
- OTA updates via EAS: Deploy JavaScript bundle updates directly to users without App Store review delays — critical bug fixes in hours.
Common use cases
SaaS Platforms
End-to-end SaaS engineering — from MVP to multi-tenant scale
We've seen what happens when a promising MVP hits a wall at 500 tenants. Our SaaS builds are architected for multi-tenancy, observability, and compliance from day one — so your scale-up doesn't require a full rewrite. We handle everything from schema design to Stripe billing to audit logs.
- Multi-tenancy done right: Row-level security in Postgres or schema-per-tenant — chosen based on your isolation requirements, not convenience.
- Role-based auth with NextAuth / Clerk: Organisations, teams, permissions, and SSO out of the box. We configure it; you own it.
- Stripe billing integration: Subscriptions, usage-based pricing, proration, invoice webhooks, and a self-serve billing portal — the full Stripe suite.
- Admin panels & analytics: Internal operator dashboards with impersonation, feature flags, and real-time usage metrics from day one.
- SOC-2-ready foundations: Audit logs, secret rotation, environment separation, and dependency scanning baked in — not retrofitted.
Common use cases
How We Work
Our Delivery Process
Every engagement follows the same disciplined process — because discipline is what makes the difference between an agency that demos well and one that ships on time.
Discovery
We spend time understanding your users, business model, and technical constraints before a single line is written. This session typically uncovers scope that would otherwise arrive as expensive change requests.
Architecture
Data model, system design, tech stack selection, and a rough component tree. We share this as a written document — you know exactly what we're building before we start.
Build
Two-week sprints, daily standups, and a shared Notion board so you see progress without chasing us for updates. Feature branches reviewed and merged by senior engineers only.
QA
Automated unit tests, Playwright end-to-end flows, cross-browser checks, and a structured UAT session with your team before anything goes live.
Deploy
Zero-downtime deployments with rollback capability. We configure CI/CD pipelines, observability dashboards, and error alerting so day-one production is boring — in the best way.
Support
Three months of post-launch support included in every engagement. We monitor, patch, and respond — because shipping is not the finish line.
Our Stack
Modern Tools. Battle-tested in Production.
We pick tools based on ecosystem maturity, developer experience, and long-term maintainability — not hype.
Why Bizotic
Why Companies Choose Us for Web & App Development
Performance-first builds
95+ Lighthouse scores are a baseline requirement, not a stretch goal.
Transparent estimates
Fixed-scope quotes or time-and-material with weekly budget tracking — your choice.
Modern stack only
We don't maintain a jQuery portfolio. Every project uses battle-tested, actively maintained tools.
In-house team in Kolkata
No subcontracting. The engineers you meet in discovery are the engineers who write your code.
Full code ownership
You own 100% of the repository and IP from day one. No lock-in, no proprietary platforms.
Post-launch support
Three months included; extended SLA retainers available for teams that want an ongoing engineering partner.
Pricing
Transparent Pricing. No Surprises.
Every engagement starts with a fixed written estimate. These tiers give you a ballpark — the final number is always agreed before we start.

What Our Clients Say
Real feedback from real teams we've shipped products with.
“Bizotic rebuilt our checkout flow in Next.js — conversion went up 28% in the first month. They delivered on time, with zero drama, and the code is actually clean.”
Priya Sharma
Founder, RetailLink
“We needed a React Native app with offline sync for our field agents. Bizotic delivered it in eight weeks. The architecture they chose has held up perfectly at 3x our initial load.”
Arjun Mehta
CTO, FieldForce India
“They built our entire SaaS platform — multi-tenant Postgres, Stripe billing, team permissions. The foundation is so solid that our own developers love onboarding to the codebase.”
Sonal Bose
Co-founder, ClearBooks SaaS
“The Bizotic team flagged scaling issues in our data model before they became problems. That kind of proactive engineering saved us a painful rewrite six months later.”
Ravi Kulkarni
Director, LogiTrack Logistics
