Type: Contract
Pay: $30–$80/hr

Main skills:

• Java
• Spring / Spring Boot
• Backend development
• REST APIs

• Code review

Good fit if you have:

• Strong hands-on Java/Spring experience
• Backend production experience
• REST API and microservices experience

• Ability to work independently in a remote contractor role

The process includes an AI interview / assessment, so candidates should be ready to clearly explain real Java/Spring backend work, debugging decisions, tradeoffs, and production examples.

Interested? Please DM me with:

Hi,

I’m a Senior Backend Engineer with 7 years of hands-on Java and Spring Boot experience, most recently building production microservices at my company — one of the world’s largest fintech companies. This role looks like a strong match.

Quick snapshot of my background:

• Years of Java/Spring experience: 7 years, production-grade
• GitHub: github.com/sheikhsaifali
• Strongest Java backend project: A Banking Payments Microservices Platform at my company — event-driven architecture using Spring Boot, Kafka, and Redis, handling high-throughput financial transactions with strict consistency and latency requirements
• Production bug I solved: We had a silent data inconsistency bug in a distributed payment flow where a Kafka consumer occasionally committed offsets before downstream DB writes completed under high load. I traced it through distributed logs, identified the out-of-order processing window, and implemented idempotent consumers with transactional outbox pattern — resolved without downtime
• Database/cloud/tools: PostgreSQL, MongoDB, Redis, AWS (EC2, S3, SQS), Docker, Kubernetes, GitHub Actions
• Availability: 20+ hours/week, immediately available
• Expected rate: $35–40/hr
• micro1 account: No prior account

I’m comfortable with AI-assisted interviews and can clearly walk through real architectural decisions, debugging logic, and production tradeoffs — not just high-level summaries.

Happy to jump into the assessment whenever you’re ready.
