From Code Enthusiasts to Professional Team
Evidence-Based Development Practices
Our approach combines proven software engineering principles with modern Python best practices.
Code Quality Standards
We adhere strictly to PEP 8 style guidelines and employ automated linting tools to maintain consistency across all projects. Code reviews are mandatory before any merge, ensuring multiple sets of eyes catch potential issues. Type hints are used throughout to improve code clarity and enable static analysis. Our code must pass comprehensive unit tests, integration tests, and meet coverage thresholds before deployment.
Architectural Principles
We design systems with modularity and separation of concerns at the forefront. Each component has a clear, single responsibility and communicates through well-defined interfaces. This approach allows individual pieces to be tested, maintained, and upgraded independently. We favor composition over inheritance and use design patterns appropriately without over-engineering solutions. Scalability considerations are baked into the architecture from day one.
Security and Reliability
Security is integrated into our development process rather than added as an afterthought. We implement input validation at system boundaries, use parameterized queries to prevent injection attacks, and follow the principle of least privilege for system access. Error handling is comprehensive but doesn't expose sensitive information. Logging captures meaningful events for debugging while respecting privacy. Regular dependency updates address known vulnerabilities.
Documentation and Knowledge Transfer
Documentation is written alongside code, not after the fact. Docstrings explain function purpose, parameters, return values, and potential exceptions. Architecture documents describe system structure and design decisions. README files provide setup instructions and usage examples. API documentation is generated automatically from code annotations using tools like Sphinx. We conduct handover sessions to ensure your team understands the codebase and can maintain it effectively.
Meet the PyCore Developers
A small team of experienced Python developers based in Cyprus, each bringing unique expertise to every project.

Eleni Andreou
Expert in creating efficient automation solutions and data processing pipelines. Focuses on streamlining workflows and reducing manual overhead. Strong background in scripting and system integration.
Nikos Hadjicostis
Handles both backend Python development and integration with frontend systems. Experienced in web frameworks, database optimization, and deployment automation. Ensures seamless end-to-end functionality.
Our Values and Expertise
At PyCore, we believe in transparency, technical excellence, and long-term partnerships. Our values shape how we work with clients and approach every development challenge. We prioritize clear communication, ensuring you understand not just what we're building but why we're making specific technical choices. When trade-offs arise between different approaches, we present options with honest assessments of pros and cons.
Technical expertise forms the foundation of our services. Our team stays current with Python's evolution, from language features to ecosystem tools. We're proficient with Django, Flask, FastAPI for web applications; pandas and NumPy for data processing; Celery for task queues; SQLAlchemy for database interactions; and pytest for testing. We understand deployment environments from traditional servers to containers and serverless architectures.
Quality is non-negotiable in our work. Every project follows our established standards for code review, testing, and documentation. We don't cut corners to meet deadlines; instead, we work with you to set realistic timelines that allow proper engineering practices. This approach results in fewer bugs, easier maintenance, and software that performs reliably in production.
We value continuous improvement both in our technical skills and processes. Regular team discussions review what worked well and what could be better on completed projects. We invest in learning new tools and techniques that could benefit our clients. This commitment to growth ensures we're delivering modern solutions that leverage the latest capabilities while maintaining stability.
Collaboration defines our client relationships. We work as an extension of your team, not as distant contractors. Regular check-ins, clear progress reports, and open communication channels ensure you're never in the dark about project status. We encourage questions and feedback, viewing them as opportunities to align our work with your needs.
Our expertise extends across industries and use cases. We've built custom CRM systems, automated reporting tools, data analysis platforms, integration layers between disparate systems, RESTful APIs serving mobile and web applications, and specialized business logic implementations. Each project adds to our knowledge base, allowing us to bring relevant experience to new challenges.
Ready to Work Together?
Let's discuss how PyCore can help with your Python development needs. We're happy to answer questions about our approach, process, or specific technical requirements.
PyCore emerged from a simple observation in 2013: many businesses needed reliable Python solutions but struggled to find developers who understood both clean code principles and practical business requirements. What started as a small consulting practice in Limassol has grown into a dedicated development team serving clients across Cyprus and internationally.
Our approach is grounded in Python's philosophy of readability and simplicity. We believe software should be maintainable not just by its original author, but by any developer who encounters it. This principle guides every line of code we write, every architecture decision we make, and every project we undertake. Over the years, we've refined our processes to balance technical excellence with practical delivery timelines.
The team has evolved alongside Python itself, adapting to new language features and frameworks while maintaining core principles. We've worked on diverse projects ranging from data processing pipelines handling millions of records to automation scripts that save hundreds of work hours monthly. Each project adds to our collective knowledge and strengthens our ability to anticipate challenges before they arise.
Being based in Cyprus provides a unique advantage. The island's position at the crossroads of Europe, Asia, and Africa gives us insight into diverse business practices and technical requirements. We work with local startups, established enterprises, and international clients, bringing a global perspective to every project while maintaining the personal touch of a local team.
Our mission extends beyond writing code. We aim to empower our clients with solutions they can understand, maintain, and extend. Every project includes comprehensive documentation, clear code comments, and knowledge transfer sessions. We view ourselves as partners in your success, not just service providers executing specifications.
