E-commerce and ticketing platform development
Saksham Jain builds e-commerce storefronts and ticketing platforms where inventory stays correct under load: pessimistic or optimistic locking chosen per case, Redis reservation holds, cached server-side pricing and idempotent payment webhooks. Live examples are Skyxis, a D2C audio store, and FindYourVibe, an event ticketing marketplace.
Works with technology companies, startups and product teams in India and internationally, remotely.
What you get
- Catalog, cart, wishlist, quick view and checkout
- Guest cart that merges into the account on login without losing items
- Inventory re-checked at checkout so a stale stock badge never sells a gone item
- Server-side pricing and promos, cached in Redis and invalidated on change
- Order events published to a queue so checkout never waits on email
Proof from shipped products
- Skyxis: D2C audio store; optimistic stock locking across many SKUs, correct under 100+ concurrent checkouts.
- FindYourVibe: Event ticketing; pessimistic lock on the last tickets plus Redis hold, no overselling under 300+ concurrent buyers in testing.
How the work runs
- Understand requirements. Business requirements, workflows, edge cases, and user journeys — before any UI or schema gets touched.
- Architect the solution. Database design, APIs, permissions, scalability, and deployment planning, mapped out before a line of production code.
- Build production systems. Type-safe APIs, reusable frontend, optimized backend, and testing — built for real load, not a demo.
- Optimize & ship. Performance tuning, monitoring, documentation, deployment, and maintenance until it's genuinely production-ready.

Common questions
How do you stop overselling during a high-demand drop?
Decrement stock inside a short transaction with a pessimistic row lock on the hot item, reserve each unit in Redis with a time-to-live, and make the payment webhook idempotent on order ID. The second buyer waits milliseconds and sees sold out; abandoned checkouts release their stock automatically.
How much does it cost and how long does it take?
Indicative ranges for an e-commerce or ticketing platform are $550 to $1,900 (about ₹45,000 to ₹1.6 lakh) over 5 to 10 weeks, depending on user roles, workflows, integrations and the deadline. Treat this as a starting point: a fixed quote follows a requirements conversation, before any build starts, so the price reflects real scope.
