Responsibilities & Context:

You will be responsible for building the entire backend system from zero to MVP and making it ready for real users. This role is about clarity, and execution, not just writing code.

1. Core Backend Architecture

• Design and build the main backend architecture from scratch

• Decide service structure, codebase organization, and system boundaries

• Build systems that are simple first, but scalable later

• Think long-term while delivering fast for MVP

2. API Design & Integration

• Design clean, consistent, and well-documented APIs

• Ensure smooth integration with:

  • Frontend (web)

  • Android app

  • iOS app

• Handle request validation, error handling, pagination, and versioning

• Make APIs easy for other developers to use without confusion

3. Authentication, Authorization & Security

• Implement secure authentication systems (token-based, session-based, etc.)

• Manage roles, permissions, and access control

• Protect APIs from common threats (rate limiting, input validation, abuse prevention)

• Secure secrets, keys, and environment variables properly

4. Data Storage & Management

• Design and manage databases (SQL / NoSQL where appropriate)

• Handle structured data, unstructured data, and metadata

• Ensure data consistency, indexing, and performance

• Plan for backups, recovery, and data safety from day one

5. Cloud, Infrastructure & Performance

• Deploy backend services on cloud infrastructure

• Configure servers, containers, storage, and networking

• Optimize performance for speed and cost

• Handle concurrency, background jobs, queues, and async tasks

6. Reliability, Monitoring & Debugging

• Implement logging, monitoring, and alerting

• Identify and fix performance bottlenecks

• Debug production issues calmly and systematically

• Make the system stable before adding complexity

7. CI/CD & Development Workflow

• Set up clean development, staging, and production environments

• Automate builds, tests, and deployments

• Write readable, maintainable, and testable code

• Follow clear Git workflows and code review practices

8. Collaboration & Ownership

• Work closely with frontend, Android, and iOS developers

• Communicate API changes clearly and early

• Divide responsibilities cleanly with another backend engineer

• Take ownership of backend decisions and outcomes

9. Use of AI & Modern Tools

• Use AI tools to improve productivity (code generation, debugging, design)

• Write effective prompts and validate AI output carefully

• Know when to trust AI and when to rely on engineering judgment

10. MVP Delivery Mindset

• Focus on delivering a working, stable MVP, not over-engineering

• Prioritize correctness, security, and clarity

• Build systems that can grow without full rewrites

• Take responsibility until the backend is production-ready
