## Case studies

- [Django to React with a Claude skill set](https://balajisankar.com/work/django-to-react-ai-migration): Procurement / B2B SaaS. I built a Claude Code skill set that knows how to port a legacy Django screen to our React stack, then let it carry out the migration of four live project boards.
- [Chargebee Docs](https://balajisankar.com/work/chargebee-docs): B2B SaaS / subscription billing. I moved a subscription-billing leader’s product documentation off a proprietary markup and a Java build onto a modern React site.
- [Vehicle Dealer Hub](https://balajisankar.com/work/vehicle-dealer-hub): Vehicle platform / dealer operations. I merged a standalone upfitter portal into the main dealer dashboard of a vehicle platform: one login, one design system and one codebase, with no business logic lost.
- [Simfoni Suite](https://balajisankar.com/work/simfoni-suite): Procurement / spend analytics / B2B SaaS. I’m rebuilding a live procurement suite one product at a time, without ever switching it off.
- [Scabbr](https://balajisankar.com/work/scabbr): EdTech / student transport safety. Live school-bus tracking, end to end.
- [AI Sales Copilot](https://balajisankar.com/work/ai-sales-copilot): Sales tech / AI SaaS. An AI sales assistant that researches each prospect and drafts outreach across email, LinkedIn and WhatsApp, with a review queue so a rep approves every message - plus a Chrome extension that works inside Gmail and LinkedIn.
- [Storybook Print Engine](https://balajisankar.com/work/storybook-print-engine): D2C ecommerce / print-on-demand. From checkout to printing press for a personalised book brand selling in two countries.
- [Ubox](https://balajisankar.com/work/ubox): Hospitality / venue booking. Online booking for a private mini-theatre and celebration venue: hall browsing, time slots, add-ons and online checkout, backed by a NestJS API and a staff dashboard - later simplified and handed over cleanly.
- [Marketplace Analytics](https://balajisankar.com/work/marketplace-analytics): E-commerce / seller tools / SaaS analytics. A profit-first analytics cockpit for brands selling on Amazon, Flipkart and other Indian marketplaces.
- [Industrial Sales CRM](https://balajisankar.com/work/industrial-sales-crm): Industrial manufacturing / B2B sales. A custom sales CRM built around how an industrial manufacturer really sells: pipeline, targets, ERP-backed billing and leadership-grade funnel reports for a field sales force spread across India.
- [Learning Habit App](https://balajisankar.com/work/learning-habit-app): Edtech / K-12. A platform that helps children build a daily learning habit: a playful learner app with schedules, journals and voice answers, and a console where parents approve content and experts give feedback.
- [Tax API Portal](https://balajisankar.com/work/tax-api-portal): Fintech / tax compliance / developer tools. The public developer portal for a global tax-compliance platform: API references generated from Swagger, integration guides, SDK docs and demos that make live API calls right from the page.
