I am Sumit Joshi from Sacesta Technologies. I will integrate a single, reliable UPI flow that supports both customer collections and partner payouts, with real-time status, webhooks, and clean reconciliation in your existing backend. Preferred stack • Backend: Node.js or your current backend with REST webhook handlers • DB: Postgres or your current DB for transaction ledgering • Gateway: Razorpay or Cashfree UPI, based on your entity type, payout needs, and compliance What I will build • UPI collect on web and mobile with secure order creation and signature verification • Webhooks and callback handling for success, pending, failed, refunded • UPI payouts workflow with idempotency, retry rules, and clear error codes • Admin-triggered payouts and optional automated payout queue • Transaction dashboard endpoints for status, timelines, and audit logs What I need from you • Gateway account access plus API keys for sandbox and live • Webhook secret and allowed IPs or signature settings • Your existing backend repo access and current payment data model • Partner payout rules: when to pay, limits, and required identifiers Testing and rollout • Sandbox validation, then controlled live rollout right after approval, with monitored logs and rollback plan Questions • Do partners receive payouts to UPI ID or bank account, or both? • Should payouts be instant on order completion, or batched on a schedule? Regards, Sumit Joshi

Hi — I can add a clean UPI pay-in/pay-out flow to your platform, integrate it with your existing back-end, and deliver sandbox-tested + live webhooks, real-time statuses and robust error handling. Relevant proof: - Experienced Full Stack Developer able to implement backend integrations, APIs and admin flows needed for payments. - I build reliable webhook-driven flows, idempotent transaction handling, and end-to-end sandbox → live deployments. Short plan: - Approach: connect your backend to a UPI PSP/aggregator via their API, implement pay-in (collect) and pay-out endpoints, webhooks, retries, idempotency and secure credential storage. - Milestones (est.): discovery & spec 1 day; sandbox integration & web UI for payouts 2–3 days; testing, fixes & go-live support 1–2 days — total 5–7 days. - Quality & testing: unit/integration tests, webhook simulator, end-to-end sandbox verification, logging/alerts and live smoke tests. Questions: 1) What is your current backend stack (Node/Python/Ruby/Java)? 2) Do you already have a UPI PSP/aggregator or sandbox API keys, or should I recommend one? If that works I’ll start immediately and provide a fixed quote — you can check my reviews on my profile.

I specialize in high-concurrency, event-driven backends and have engineered systems handling 10K+ actions/hour. I will deliver a hardened, 100% UPI-focused integration using Node.js/Express and PostgreSQL to ensure your collections and payouts are atomic, traceable, and lightning-fast. Why I’m the right engineer for this urgent roll-out: Reliable Webhooks: I’ve built transactional outbox patterns (as seen in my Synq Flow project) to ensure you never miss a payment confirmation or payout status. Idempotency Focus: I implement strict idempotency keys so that even with network retries, a partner is never paid twice and a customer is never double-charged. Real-time Monitoring: I’ll set up a clean logging system using Redis/Postgres so your admin panel reflects the exact state of every transaction instantly. Production-Ready: My experience with AWS and CI/CD means I can move from sandbox to live deployment securely and swiftly. Tech Stack: Node.js (Backend), PostgreSQL (Ledger), Redis (Status tracking), Razorpay/Cashfree (UPI API).
