Database & API Design

  • Model, query, and optimize relational data structures in PostgreSQL.
  • Design, build, and maintain clean RESTful APIs and microservices.

Code Quality & Best Practices

  • Apply SOLID principles, basic design patterns, and clean code principles to write maintainable, scalable, and self-documenting code.

Testing & Quality Assurance

  • Implement comprehensive test suites using Jest, React Testing Library, or backend testing frameworks (e.g., PyTest) to maintain high code coverage and prevent regressions.

Agile Execution

  • Actively participate in Agile ceremonies (sprints, stand-ups, retrospectives, and planning) to deliver quality code incrementally.

Collaboration & Mentorship

  • Partner with cross-functional teams and mentor junior engineers through constructive code reviews and technical guidance.

Requirements & Qualifications

Technical Skills

Frontend

  • 3–5 years of hands-on experience with React, TypeScript, Tailwind CSS, and modern UI component libraries like Shadcn UI.

State & Data Fetching

  • Experience with modern client-side state management and data-fetching libraries (TanStack Query, Zustand, or Redux Toolkit).

Backend

  • Strong expertise in server-side development using Node.js or Python (FastAPI).

ORMs & Data Layer

  • Experience with ORMs or Query Builders such as Prisma, Drizzle, TypeORM, or SQLAlchemy.

Database

  • Strong expertise in relational database modeling, query optimization, indexing, and management with PostgreSQL.

System Design & Patterns

  • Practical experience applying SOLID principles, basic software design patterns (Factory, Singleton, Observer, etc.), and clean architecture principles.

API Development

  • Solid grasp of API design standards, authentication/authorization using OIDC and OAuth 2.0, and backend-frontend integration.

Testing

  • Proficiency in unit, integration, and component testing using Jest, React Testing Library, and PyTest.

Methodologies

  • Strong operational knowledge of Agile/Scrum software development workflows.

Culture & Mindset

Analytical & Data-Driven

  • Problem-solver who relies on metrics, root-cause analysis, and objective evidence to make sound technical and design choices.

Entrepreneurial & Agile

  • Thrives in a fast-paced, high-growth environment, displaying high ownership, adaptability, and resilience.

Leader & Doer

  • Balanced builder who can lead initiatives and mentor peers while remaining deeply hands-on in code implementation and debugging.

Communication

  • Exceptional written and verbal communication skills to articulate technical concepts, align with stakeholders, and author quality documentation.

Nice to Have

Database & Caching

  • Experience with caching strategies using Redis, or exposure to NoSQL databases (e.g., MongoDB).

Architecture & APIs

  • Exposure to GraphQL, microservices architecture, and event-driven patterns (e.g., Kafka, RabbitMQ).

Cloud & DevOps

  • Hands-on experience with containerization (Docker, Kubernetes), CI/CD pipelines, and cloud infrastructure (AWS, GCP, or Azure).

Security & Performance

  • Understanding of web security best practices (OWASP Top 10, OAuth2, JWT) and web performance optimization techniques.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
