Nothing falls between two contractors. - SaaS Product Development: Multi-tenant products with billing, roles and usage limits built in from the first sprint rather than retrofitted after launch. - AI Integration & Automation: Claude, GPT and embedding pipelines wired into real workflows, with provenance and confidence thresholds so the output can be trusted. - iOS & Android Apps: One React Native or Flutter codebase shipped to both stores, sharing the same API and data model as the web product instead of drifting from it. - REST API Development: Versioned, documented APIs with authentication, rate limits and idempotency, the parts that decide whether integrations stay stable. - Dashboards & Admin Panels: Internal tools that stay fast as data grows, using pre-aggregated reads instead of dashboards that scan the whole history. - Payment Gateway Integration: Stripe and Razorpay implemented properly, webhook replay safety, refunds, mandates and a ledger that reconciles. - CRM & Business Systems: Lead capture, pipelines and follow-up automation that reacts to what a customer actually did, not to a schedule set days earlier. - Performance Optimization: Profiling a slow product and fixing the cause: query plans, N+1s, cache layers, bundle weight. Not more hardware. ## Case studies - [SHINY](https://www.naveentehrpariya.dev/projects/shiny-soms): Scheduling and operations for Japanese welfare providers, on the web and in the hand.
