Custom Development

This is the nLotus Method applied bespoke — one architect-led delivery method, expressed here as a one-off engagement built to your exact requirements, instead of the productized Products Portfolio or our own shipped proof of the Method, MDWeaver. From custom web application development to native mobile and desktop apps, we pick the right stack for your problem instead of forcing a one-size-fits-all template. From a single API to a multi-platform product, we cover the full lifecycle, and every engagement now runs on our AI-powered delivery model — architect-led, AI-accelerated.

What Is Custom Development at nLotus?

Custom Development is the nLotus Method applied bespoke: one architect-led delivery method, expressed as a one-off engagement built to a client's exact requirements, instead of the productized Products Portfolio or nLotus's own shipped proof of the method, MDWeaver. It covers full-stack engineering across every layer — from custom web application development to native mobile and desktop apps, backend APIs and realtime services, data and storage design, cloud and DevOps, AI integrations, security and compliance, and documents and reporting. nLotus picks the right stack for each problem — across .NET, React, Next.js, Angular, SwiftUI, Kotlin, and Avalonia — rather than forcing a one-size-fits-all template. Every custom engagement now runs on the same AI-powered delivery model as the rest of the portfolio: architect-led, AI-accelerated, with senior architects reviewing every line, and a written commitment that client code and data are never used to train AI models.

Capabilities

What Does nLotus Custom Development Cover?

Full-stack engineering across every layer and platform — designed, built, secured, and shipped.

Responsive, accessible, high-performance web apps — from marketing sites to complex multi-tenant SaaS dashboards.

  • ASP.NET Core (Razor Pages & MVC), Node.js
  • React, Next.js, Angular, Vue, TypeScript
  • Tailwind CSS & design systems
  • Progressive Web Apps (offline-first)

Mobile App Development

Native and cross-platform mobile apps with offline sync and push notifications, published to the App Store and Play Store.

  • iOS — SwiftUI & Core Data
  • Android — Kotlin & Jetpack Compose
  • React Native & Flutter
  • Push (FCM / APNs) & deep linking

Desktop Applications

Cross-platform desktop software with a single codebase running natively on Windows, macOS, and Linux.

  • Avalonia UI on .NET
  • Native OS integration & file handling
  • Audio, media & data-intensive tooling
  • Offline-capable, installable builds

Backend, APIs & Realtime

Robust, well-architected services that scale — with clean separation, background processing, and live updates.

  • REST & GraphQL APIs
  • EF Core & Dapper data access
  • Realtime with SignalR / WebSockets
  • Background jobs — Hangfire, Quartz.NET

Data & Storage

The right database for the workload — relational, document, or in-memory — modelled for performance and integrity.

  • SQL Server, MySQL, PostgreSQL
  • MongoDB & document stores
  • Redis caching & queues
  • Migrations, seeding & reporting

Cloud & DevOps

Cloud-native deployment with automation, observability, and cost discipline built in from day one.

  • AWS architecture & cost optimization
  • Docker & Kubernetes
  • CI/CD pipelines & Terraform
  • Monitoring, logging & alerting

AI & Integrations

Intelligent features and seamless third-party connections that automate work and remove friction.

  • Claude / Anthropic & Google GenAI
  • Chatbots, document processing & OCR
  • Payments — Razorpay, Stripe, PayU
  • WhatsApp Business API, SendGrid, Google Calendar

Security & Compliance

Security designed in, not bolted on — protecting data and access at every layer of the stack.

  • Role-based access control (RBAC) & JWT
  • Encryption at rest & in transit
  • PCI DSS-aligned payment flows
  • Audit logging & vulnerability assessments

Documents & Reporting

Pixel-perfect documents and exports generated on the fly — invoices, statements, and reports.

  • PDF generation with QuestPDF
  • HTML-to-PDF via PuppeteerSharp
  • Excel & CSV exports
  • Templated, branded outputs
