ADDS CLASSIFIED

About this project

ADDS CLASSIFIED is a custom product designed, developed, tested and deployed by our team, with the source code and accounts handed over to the client.

A classified-ads mobile application: users list items, other users find and contact them. The product problem is trust and noise. A classifieds app fails when the listings are stale, duplicated, or fake, long before it fails on features.

What a build like this covers

• Listing creation with category-specific fields, photos and price
• Search with category, location and price filters
• Listing lifecycle: active, expired, sold, renewed, so dead listings leave the feed on their own
• In-app contact between buyer and seller without exposing phone numbers by default
• Reporting and admin moderation queue
• Featured and bumped listings as a monetization path

What we watch for in classified work

Image upload is where classifieds apps break on real networks. Photos are compressed on-device before transfer and uploads resume rather than restart, because a seller on a weak mobile connection will abandon a listing that fails at 80%.

Stack

We build classified products in Flutter and native Android and iOS on the client, with Node.js and NestJS services behind them, TypeORM over PostgreSQL or MySQL where the data is relational, MongoDB where it is not, and Firebase for authentication, push and analytics. Web panels are React. The choice follows the product. We do not start from a template and bend the requirements to fit it.

How we work

Every project starts with a written scope and screen list, moves through design and iterative development with regular demos, and ends with testing on real low-end devices before release. Clients own their code, repositories and store accounts. Where it adds genuine value, we integrate AI features (assistants, document extraction, recommendations) rather than bolting them on for show.
