Hire Backend Developers across Node.js, Java, Python, Go, PHP and .NET

Cortance backend developers work across Node.js, Java, Python, Go, PHP and .NET, layering on frameworks like Spring Boot, Django, Laravel, NestJS and Express.js depending on the job. They build REST and GraphQL APIs, split monoliths into microservices, and wire up message queues such as Kafka and RabbitMQ for systems that cannot afford to drop an event.

On the data side they work in PostgreSQL, MySQL, MongoDB and Redis, and deploy to AWS, Azure or GCP with CI/CD pipelines, logging, metrics and tracing rather than a single health check endpoint. Whether you need a dedicated backend team, one senior engineer to lead architecture decisions, or staff augmentation for a specific sprint, the match starts from your stack, not a generic developer profile.

What have Cortance backend engineers delivered?

Our developers' backend portfolio spans fintech, e-commerce and internal enterprise platforms that most teams never see outside an NDA. Recent work delivered:

1. Payment infrastructure. Kamal G. built internal APIs that connect a fintech platform to external payment providers, cutting processing latency by 20%.
2. Real-time multi-tenant platforms. Dmitry A. moved a customer support chat platform from a legacy AdonisJS backend to NestJS while it served over a thousand concurrent chat clients. He replaced automatic dialog assignment with a queue operators claim from, and cut one heavily used query from 1.5 seconds to 600 milliseconds.
3. Java microservices for internal banking. Anar K. designed the microservices that replaced a legacy monolith behind a bank's internal operations platform, with role-based permissions for transfers, payments, loan applications and card orders.
4. Banking and lending backends. Ivan S. masked personal data in logs and kept an audit trail for every credit decision on a .NET loan platform. Serhii Kro. built loan application, repayment and document modules for a Symfony lending platform integrated with Paysera, Kevin and Unnax.

Match the seniority to the job, not just the budget

1. A mid-level engineer owns a service independently, writes tests without being asked, and debugs production issues without hand-holding, which covers most of the feature work companies hire for.
2. A senior backend engineer decides where a monolith should split and is the person you want in the room before code gets written, not after it breaks in production.

Cortance matches you to the level the work requires instead of defaulting everyone to senior rates.

Five vetting stages before you see a profile

Every backend engineer goes through the same five-stage vetting process: application, AI screening, HR interview, technical assessment and profile completion. Backend developers hired through Cortance typically cost $30 to $50 an hour, depending on seniority and stack. So whether you are hiring for a compliance-heavy fintech or healthcare product or a straightforward internal API, the same vetting bar applies to every candidate.

AI-assisted backend development

We prefer backend engineers who are actively developing in GenAI, and on secure banking or healthcare projects that use stays inside the client's security rules. Denys P., a senior PHP and Symfony engineer, worked with Claude Code and Codex on a capacity management system for Astreya, an IT managed services provider. The system shows current demand and supply of technicians and forecasts the next two weeks. AI tools speed up test writing and code review, and what ships to production still goes through the same review as any other change.
