Frontend Development

  • Support the development and maintenance of user-facing web applications and interfaces using React / Next.js with TypeScript.
  • Assist in developing, testing, debugging, and improving frontend features based on business and technical requirements.
  • Work with the development team to improve application usability, functionality, and performance.
  • Follow coding standards and development practices (Git, code reviews, linting/formatting) to maintain code quality and consistency.

Backend Development

  • Support the development and maintenance of backend services, APIs, and application logic using Node.js (Express / NestJS).
  • Assist in integrating REST APIs, relational databases (PostgreSQL / MySQL), and third-party services into applications.
  • Support testing, debugging, and troubleshooting of backend functionality and system issues.
  • Assist in improving application performance, reliability, and functionality.

Development & Business Support

  • Translate business requirements into practical technical solutions in collaboration with relevant stakeholders.
  • Assist in developing internal tools, automation, or features that support business and operational needs — including workflow automation with n8n to connect internal systems and reduce manual work.
  • Participate in testing, documentation, code reviews, and development activities.
  • Support troubleshooting and continuous improvement of existing applications and systems.

Collaboration & Continuous Learning

  • Collaborate with developers, data teams, and business stakeholders to understand requirements and deliver solutions.
  • Stay updated on relevant technologies, tools, and development practices.
  • Take ownership of assigned tasks, communicate progress and challenges, and seek feedback to continuously improve technical skills.

Tech Stack You'll Work With

  • Frontend: React / Next.js, TypeScript, HTML/CSS
  • Backend: Node.js (Express / NestJS), REST APIs
  • Database: PostgreSQL / MySQL
  • Automation & Integration: n8n, webhooks, third-party APIs
  • Tools: Git / GitHub, Docker, Postman, CI/CD basics

Requirements

  • Able to commit to a minimum 3-month internship period.
  • Currently studying Computer Science, Computer Engineering, IT, or a related field (or self-taught with equivalent projects).
  • Basic understanding of JavaScript/TypeScript, HTML/CSS, and how web applications and APIs work.
  • Familiarity with any modern frontend framework and any backend/database is a plus — experience with Node.js, n8n, or other automation tools is a strong plus.
  • Willing to learn, take ownership, and communicate clearly with both technical and non-technical teammates.
