Backend • Middle • 5+ years exp • 31 year • Lagos, Nigeria • In office, Partially remote, Fully remote • Relocation • English: C1
Backend .NET engineer (early middle level) focused on building REST services and identity flows with practical integration glue as a strength. The strongest proven skill is building simple CRUD REST endpoints and MongoDB-backed services as shown in AgentyJobApplication/Services/MyResumeService.cs and AgentyJobApplication/Controllers/AgentyJobApplicationController.cs. There is limited evidence of production-grade observability, resilience patterns, advanced performance tuning or automated test coverage in the public code.

UI-focused frontend engineer (middle level) with a clear strength in building polished, responsive landing experiences and a custom client-side i18n solution. The strongest proven skill is the custom i18n engine that handles locales, RTL, DOM text replacement and persistent language selection (Amatis-dev/landing/assets/js/i18n.js). There is limited evidence of complex state management, automated testing, server-state handling or advanced build/tooling in the public code.

Backend • Intern • 5+ years exp • Hyderabad, India
Entry-level QA-focused generalist working with JavaScript projects, assessed at an Intern level with a primary strength in dependency maintenance and security updates. The clearest concrete artifact is the presence of multiple automated Snyk dependency-upgrade pull requests touching package.json and package-lock.json that show attention to dependency security. There is no human-authored source, test code, CI parametrization, or domain-specific logic available to evaluate test automation, API contract testing, performance engineering, or system design.

Backend • Middle • Warsaw, Poland • In office, Partially remote, Fully remote • Relocation
App-focused frontend engineer (middle level) specializing in building stateful React and Next.js business applications. The strongest proven skill is client-server state and data-flow design as demonstrated by the React Query hooks and invalidation logic in Cringenut/tapi-frontend/features/staff/hooks/useStaffAvailability.ts and the centralized reducer/context in Cringenut/ProductManagementApp/src/app/context/ProductContext.js. The public code has limited measured performance work, limited accessibility engineering and lacks automated tests or advanced cross-browser and internationalization handling.
