Catalog
Condition grading as a first-class field.
Every listing carries structured condition, warranty, and spec data — so a product page answers the buyer’s real question: “what exactly am I getting?”

A trust-first marketplace for phones and electronics in Bangladesh — a graded catalog, live bidding, a device trade-in flow, and a checkout wired to local payments. We shipped the storefront, seller tools, and the buy/sell/swap experience behind it.

I.The brief
Second-hand electronics in Bangladesh trade in Facebook groups — long on risk, short on trust.
Buyers couldn’t tell a graded device from a gamble, sellers couldn’t price fairly, and exchanges meant meeting a stranger with cash. There was no neutral platform that handled condition, pricing, payment, and warranty in one place.
Flipper needed a real storefront: a catalog with condition grading, a bidding mechanic for fair price discovery, a trade-in exchange path, and a checkout that accepted the payment methods people actually use — bKash, Nagad, and cards.
II.The approach
The decisions behind the work.
Bidding
Live bids for fair price discovery.
A “Latest Bids” engine lets the market set the price on resale devices instead of a guess, with clear deal badges and discount math.
Exchange
A trade-in flow, not a forum post.
Sell-your-old-device and recycle paths turn an exchange into a guided transaction with a quote — the core “flip” the brand is named for.
Payments
Checkout built for Bangladesh.
Cart and Buy-Now backed by local rails (bKash/Nagad/cards), with warranty, shipping, and billing handled at checkout.
Sellers
Onboarding so supply scales.
Tools for listing, repair, and warehouse deals so the catalog grows without a support bottleneck.

They understood the resale market here, not just the code. The exchange flow is the reason people come back.
