- Experience cleaning up/refactoring messy codebases.
- Ability to mentor mid-level and junior devs.
- Bonus: Experience with restaurant/retail tech, POS, or fintech/payments.

- Ambition to grow into CTO role (lead a larger tech org, own platform strategy).
- Strong communicator — can bridge between UK business team and India dev team.
