You will get Stripe subscriptions, billing, and payment flows set up for your SaaS
Top Rated
Project details
Stripe billing looks simple until a webhook silently fails, a proration edge case overcharges a customer, or a failed payment has no retry logic - problems that don't show up in testing, only in production with real customers.
I've built subscription billing, multi-tier pricing, and Stripe Connect marketplace payouts for live SaaS products, and I test everything in Stripe's test mode before going live.
As a Top Rated Plus developer with a 100% Job Success Score, I set this up correctly once, so you won't have to revisit it after a billing incident.

Battle Rap Ranking Platform (React + Supabase)
Kenil is an exceptionally versatile full-stack developer - equally strong on frontend and backend. He worked on BattleRapHub.com, TalkAdvantagePro.com, ImageMax, and Director's Palette, delivering quality across very different technical requirements. When we needed Replicate API integration for AI image generation, he learned it quickly and delivered with no issues.
Over time, I've come to rely on him as an essential member of my team. He's a hard worker who's proactive and detail-oriented, yet still sees the big picture. His extensive experience lets him leverage a wide range of services and tools effectively - he brought practical solutions I wouldn't have thought of.
What I really appreciate: he's not a yes-man. When I ask for his opinion, he gives thoughtful, honest feedback. He was also patient in teaching me new approaches and sharing his knowledge.
Anyone would be lucky to work with Kenil. Highly recommended for teams looking for a reliable, well-rounded developer who can own projects end-to-end.

Surat, India - 9:17 am local time
With 6+ years of architecting and shipping full-stack systems, I've built SaaS platforms, AI-powered applications, real-time dashboards, and B2B tools handling thousands of active users.
🏆 TOP 3% on Upwork · 🏅 Top Rated Plus · 💯 100% Job Success Score
💪 I use Claude Code and Cursor daily - I pick up existing codebases fast and ship features without hand-holding.
━━━ What I build ━━━
→ SaaS platforms with multi-tenant architecture, authentication, and role-based access
→ AI-powered apps: LLM integration, RAG pipelines, AI agents, OpenAI & Claude API
→ Real-time dashboards with live data, WebSockets, and complex filtering
→ Stripe billing flows: subscriptions, Connect, and payment processing
→ MVPs from zero to production, and existing codebases taken the final mile
→ No-code handoffs - take over and extend apps built in Lovable, Replit, or Base44 when founders are ready to scale beyond the builder

I don't just write code; I architect scalable solutions and take full ownership.
→ Work independently - clear specs are enough; no daily check-ins needed
→ Fast communication - responses within hours, not days
→ Proactive updates - you always know where things stand
→ End-to-end ownership from architecture to deployment on Vercel or AWS

Steps for completing your project
After purchasing the project, send requirements so Kenil can start the project.
Delivery time starts when Kenil receives requirements from you.
Kenil works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery - review your stack and pricing model
I review your current setup (or lack of one) and your pricing model - flat, tiered, or usage-based - to confirm the right scope for your tier.
Build - checkout, webhooks, and billing portal
I implement the checkout flow, webhook handling, and billing portal features included in your tier, testing against Stripe's test mode throughout.
