Subject: Backend Developer – Allo.Delivery

Please include a short note describing a backend system you’ve built that involved wallets, payments, or logistics flows.

Final Note

Allo.Delivery ;today; is a small, focused team — fewer than four people at this stage. You will be working directly with the Product Owner and Flutter Developer, shaping the core architecture that everything else will build on.

We’re not looking for someone who just codes tasks — we’re looking for a builder who treats this project as their own, makes decisions with ownership, and takes pride in seeing an idea come to life from zero to launch. If you’re passionate about creating structure from vision and love the challenge of startup simplicity, this is your place to shine.
