Company Description:
offload4u helps Indian SMEs automate workflows that cost them time and money.

Responsibilities
You are the only engineer on the product. There is no CTO above you and no team below you yet. You report directly to the founder. You will make the architectural decisions, execute them, and flag tradeoffs in plain language. If you need a junior, you can hire one and manage them.
What you will own
The full ExpoScan codebase — backend, frontend, database
Multi-tenancy architecture and migration from single-tenant to SaaS
Billing integration, tenant onboarding flows, and access control
Migration from current hosting to Railway/Vercel
MongoDB schema decisions and data integrity
Any new features scoped with the founder
Qualifications
What we need from you
4 to 7 years of fullstack experience
You have shipped a multi-tenant SaaS product in production — not designed one, shipped one
Strong on FastAPI and Python backend, comfortable with React 19
MongoDB at scale — you know when to index, when to embed, when to separate
You can read an existing codebase, understand it, and improve it without someone explaining every line
You communicate technical decisions in plain language to a non-technical founder
Based in Kolkata, comfortable working in-office
What we do not need
Someone who needs daily direction
Someone who has only worked in large teams with senior oversight
Someone who knows the theory but has not shipped Stack
