Kafka, Node, Express & TypeScript Backend Completion

I'm seeking a skilled developer to finalize the backend logic of my Node, Express, and TypeScript project.

Key Responsibilities:
- Seed a SQL Lite DB with JSON objects
- Completing database queries
- Ensuring smooth integration with SQL Lite
- Sequelize ORM w/transactions

Skills:
- Proficient in Node, Express, TypeScript (avoid 'any' at all costs)
- Extensive experience with SQL databases
- Strong problem-solving skills for backend logic
- ESLint/TSLint
- Unit Tests with Jest/Mocha
- Code Coverage with Istanbul
- Data input validation (against SQL injection)
- Data input validation (JSON Schema, as a middleware)
- Security is the most important
- Concurrency is critical as well, hence the use of Kafka (locally)

Notes:
- There is no need for a front end, this is purely a back-end mini-system.
- Around 6 APIs to build/complete
- SOLID principles
- Security first

Please bid if you have the relevant experience and can deliver high-quality work in a short period.
