FAQ
Questions candidates ask us.
Is the company independent?
Yes. FEILIU TECH is operated by OBSYRA TECH PTE. LTD., an independent legal entity backed by strategic industry partners who provide ongoing support in technology, talent and delivery.
How stable is the business?
We have a clear product roadmap and customer path, focused support from our partners over the next 6–12 months, and a B2B paid model with a clear route to cash flow.
What is the product and the tech stack today?
A mini-program demo app, the algorithm SDK and API, and the console. The backend uses a mainstream stack — Go/Java, gRPC/HTTP, Kafka/Flink, vector retrieval and PyTorch — with a strong focus on observability and rollback.
What is your advantage over large platforms?
Fast delivery, customisation, explainability and compliance. We focus on putting useful recommendation capabilities in our customers’ hands, not on running a content platform that competes with them.
What does career growth look like?
Many chances to own a core module and work directly with online metrics and customer results, on technical and management tracks with transparent performance and incentives.
