- Assess the current project status and identify unfinished features, bugs, and technical gaps.
- Develop and improve frontend interfaces and backend services.
- Build, maintain, and integrate APIs, databases, and third-party services.
- Debug existing functionality and resolve complex technical issues.
- Refactor code to improve performance, security, scalability, and maintainability.
- Implement remaining product features based on business and technical requirements.
- Write clean, reusable, well-tested code following software engineering best practices.
- Work with Git, automated testing, and deployment workflows.
- Collaborate with stakeholders to prioritize tasks, communicate progress, and meet project milestones.
- Help prepare the application for production deployment and ongoing maintenance.
Required Qualifications
- Significant professional experience as a Full Stack Engineer or Senior Software Developer.
- Strong proficiency in Python and experience developing backend applications.
- Experience with modern frontend technologies, such as JavaScript or TypeScript and React.
- Experience designing and integrating REST APIs.
- Strong knowledge of databases, data modeling, and SQL.
- Experience taking over and extending an existing codebase.
- Strong debugging, troubleshooting, and problem-solving skills.
- Familiarity with Git, automated testing, and modern development workflows.
- Ability to work independently, make technical decisions, and deliver high-quality results.
- Strong communication skills and a practical, delivery-focused mindset.
Preferred Qualifications
- Experience with Python frameworks such as Django, Flask, or FastAPI.
- Experience with React, Next.js, or similar frontend frameworks.
- Familiarity with PostgreSQL, MySQL, or other relational databases.
- Experience with Docker, cloud infrastructure, and CI/CD pipelines.
- Knowledge of application security, performance optimization, and production monitoring.
- Experience completing partially developed software products and preparing them for launch.
What Success Looks Like
- Quickly understanding the existing application and its architecture.
- Completing the remaining features and resolving critical bugs.
- Improving the reliability, maintainability, and overall quality of the codebase.
- Delivering a fully functional application that meets the project's requirements.
- Providing clear technical documentation and a maintainable solution for future development.
