# Job Skill Enhancement System

## CORE INSTRUCTION:
You are an AI that extracts and identifies coding languages and frameworks from job descriptions. Your goal is to find ALL relevant technical skills mentioned in the job posting, even if they're mentioned in different ways or aliases.

  "job": {"job_id":3653,"title":"Backend Developer, Tech Lead","company_name":"UNIwise ApS","description":"We are looking for an experienced backend developer to take up the backend tech lead role in UNIwise. \n\n \n\n\n\n\nWhat you will do \n\nAs tech lead you will be a driving force in defining and evangelizing best practices for backend development for our platforms WISEflow and WISEflow Originality. Alongside this, you will be working as a senior backend developer in one of our WISEflow teams, where you will be taking the technical lead in the team’s backend projects, ensuring we deliver the right quality at the right time. \n\n \n\n\n\n\nYou have experience working with both micro service and monolithic architectures and you have strong opinions on what good looks like. You focus on software design patterns and principles and how they can be generalized across our many services for better maintainability, extensibility and testability. \n\n\n\n\n \n\nAt the same time, you have a pragmatic mindset and know how to balance theory and practice. When to make compromises and when to stand your ground. Most importantly you appreciate input and opinions from your colleagues and are not afraid to change your mind when someone presents a different perspective. \n\n \n\n\n\n\nAs a senior developer you are used to mentoring and coaching your colleagues and enjoy conducting small training and knowledge sharing workshops for your fellow backend developers. \n\n \n\n\n\n\nYou are particularly strong on testing strategies, and care more about test relevance than test coverage, although the latter should also be high. \n\n \n\n\n\n\nUNIwise can offer some exciting challenges where you will be working on a product with millions of users, where the stakes are very high due to the nature of exams. This means we have a very high focus on quality and performance. When we build something, we build it for scale and resilience. \n\n \n\n\n\n\nOur backend stack consists of an (originally) monolithic PHP app, as well as an array of Go based microservices and a few Node- and python-based services as well. You will be working mostly in Go and PHP and should be well versed in both. \n\n \n\n\n\n\nWe host everything in Kubernetes and expect you to have familiarity with it. \n\nAs tech lead you will also be part of driving an AI agenda in product development. We believe that the combination of highly skilled developers and agentic coding has a very big potential. In this role you will be a part of defining how we can roll out agentic coding across the backend chapter to increase the development speed without compromising quality and security. \n\n \n\n\n\n\nYou will be working out of our office in Aarhus. We believe in trust and accountability, and no one will question you working from home or leaving early when needed, but your preference should be to work out of the office, and you enjoy the company of your colleagues. \n\n \n\n\n\n\nWhat you can expect from us \n\nA friendly and collaborative work environment. \nThe possibility to be part of an exciting growth journey. \nA culture built on trust and accountability that empowers creativity and encourages continuous learning professionally and personally. \nOwnership and impact based on trust and accountability. \nThe opportunity to have significant impact on our software development standards and becoming a key player in our growth journey. \n\n\n\n\nHow to Apply \n\nIf you are passionate about building software the right way, then we would love to hear from you. Please submit your resume and a cover letter detailing your relevant experience and why you are the perfect fit for this role. \n\n \n\n\n\n\nAbout Us \n\nUNIwise is a leading provider of digital exam and assessment solutions headquartered in Aarhus, Denmark. We are dedicated to enhancing the educational experience for institutions and students alike. Our innovative products, WISEflow & Wiseflow Originality, are used by some of Europe's most renowned educational institutions, facilitating millions of exams annually.","brief_summary_of_job":null,"existing_skills_from_job":["Fysisk tilstedeværelse","Fuldtid","PHP","Backend-webudvikling","Søg","Kubernetes","Microservices","Software Design Patterns","Coaching og mentorarbejde","Skalerbarhed"],"existing_skills_from_database":[]},

## TASK:
1. **Extract ALL coding languages and frameworks** mentioned in the job description
2. **Use the skill_aliases mapping** to normalize skill names (e.g., "JS" → "JavaScript", "React.js" → "React")
3. **Only include skills from the coding_categories** (languages and frameworks)
4. **Avoid duplicates** - if "JavaScript" and "JS" are both mentioned, only include "JavaScript"
5. **Be thorough** - look for skills mentioned in:
   - Job title
   - Job description
   - Brief summary
   - Requirements sections
   - Nice-to-have sections

## SKILL CATEGORIES TO EXTRACT:
- **Languages**: JavaScript, Python, Java, C#, PHP, Go, Rust, etc.
- **Frameworks**: React, Angular, Vue.js, Laravel, Django, Spring Boot, etc.

## EXCLUSION RULES:
- Do NOT include soft skills (communication, teamwork, etc.)
- Do NOT include methodologies (Agile, Scrum, etc.)
- Do NOT include general tools (Git, VS Code, etc.) unless they're specifically coding-related
- Do NOT include skills already in existing_skills_from_database

## OUTPUT FORMAT:
Return ONLY valid JSON in this exact structure:
{
  "job_id": <integer>,
  "extracted_skills": [
    {
      "skill_name": "<normalized_skill_name>",
      "category": "<languages|frameworks>",
      "confidence": <integer 0-100>,
      "mentioned_as": ["<original_mention_1>", "<original_mention_2>"],
      "context": "<brief_context_where_found>"
    }
  ],
  "reasoning": {
    "total_skills_found": <integer>,
    "skills_by_category": {
      "languages": ["<skill1>", "<skill2>"],
      "frameworks": ["<skill1>", "<skill2>"]
    },
    "duplicates_removed": ["<original_mention> → <normalized_name>"],
    "excluded_skills": ["<skill>", "<reason>"]
  },
  "confidence": <integer 0-100>
}

Return nothing outside the JSON object.
