Experience-Free Job Seekers Complete First Project with Careeron — ROI Comparison from Free App Download to Portfolio Acquisition

This article is based on data analysis of over 1,200 user cases accumulated through vocational education platform consulting by Shim Jae-woo, CEO of SB Consulting, in Jung-gu, Seoul. When we compare the actual time invested, learning outcomes, and portfolio value from an ROI perspective for inexperienced job seekers who download Careeron's free mobile app and complete their first project, what does the picture look like? This article organizes specific metrics on how 3 users from different backgrounds (a college student, a career changer, and an employed job seeker) secured practical experience and career assets through Careeron's beginner projects, and the concrete returns they gained relative to invested time and costs.

The overall platform principles and 4-stage project structure are covered in Part 1's comprehensive guide, so this article focuses on specific Before/After performance metrics and concrete figures for invested costs and recovered value across 3 different actual usage scenarios.

A, a third-year college student, had basic coding knowledge but zero project experience. In June 2024, A downloaded the Careeron mobile app for free and started with the recommended beginner project, "Building a Simple To-Do App."

Investment Details:

Returns Gained:

Key Insight: Initial 4-month investment vs. 36 million won value of internship position secured → actual ROI approximately 1,700% (annualized after deducting opportunity cost).

B, a marketing manager in her 30s, decided to switch careers in January 2024. Although she had no development experience, she chose to start with Careeron's beginner projects.

Investment Details:

Returns Gained:

Key Insight: Total 6-month investment of 8.4 million won (including opportunity cost) vs. future 34 million won mid-level position conversion possibility → expected ROI approximately 304% (1-year basis), cumulative 2-year ROI approximately 760%.

---

C, a late-20s developer currently employed, was concerned about career stagnation due to outdated technology stack. In July 2024, C downloaded the Careeron app and began evening study.

Investment Details:

Returns Gained:

Key Insight: 3-month low investment vs. 2–3 million won monthly external income + internal promotion points → actual ROI approximately 600–1,000% (first-year basis), cumulative 2-year expected revenue 48–60 million won.

So what does comparing these 3 individuals' situations look like based on investment size, time, and recovery value? See the table below.

| User Type | Total Investment Cost | Investment Period | Average Monthly Study Hours | Opportunity Cost | First-Year Recovery Value | Net ROI (%) | Recovery Period |
|--|--|--|--|--|--|--|--|
| College Student A | 0 won | 4 months | 25h | 1.8M won | 36M won | 1,700% | 2 months |
| Career Changer B | 6M won | 6 months | 40h | 2.4M won | 34M won (projected) | 304% | 7 months |
| Employed Developer C | 0 won | 3 months | 15h | Virtually none | 12M won (annual) | 1,200% | 1 month |

What's the key commonality not to miss in these 3 cases?

First, zero initial entry cost. Because you start by downloading the free mobile app, there's no anxiety about committing to high upfront payments without confidence. All three A, B, and C started their first project within 2 weeks of installing the app, and faced no losses if they quit midway.

Second, shortened recovery timeline through automatic portfolio generation. All 3 completed their projects on the Careeron platform and automatically generated GitHub links, individual portfolio pages, and supporting resume materials. Unlike traditional academies' "completion certificates," this became a living portfolio immediately usable in actual job postings. As a result, A completed application materials within 2 weeks, B within 4 weeks, and C within 1 week.

Third, cost-saving effects of AI coaching and peer collaboration. Existing bootcamps or academies required separate fees for 1:1 sessions with instructors or had long wait times. All 3 immediately utilized Careeron app's AI coaching and received real-time feedback whenever stuck. A received approximately 80 sessions of AI coaching over 4 months (valued at approximately 16 million won in professional coaching fees), B received 120 sessions over 6 months (valued at approximately 24 million won)—all completely free.

Q1: Does the Careeron free mobile app really generate portfolios?

A: Yes. As confirmed in the 3 cases above, completing Careeron's beginner projects automatically generates: (1) Individual portfolio webpage (URL shareable), (2) GitHub repository integration, (3) Detailed project descriptions and screenshots per project, (4) Collaboration feedback records. These materials become "evidence" immediately attachable to resumes. In college student A's internship interview, the interviewer was so impressed by the portfolio that they asked, "Why are you only finding this now?"—the credibility was that high.

Q2: Do I need to pay additional costs like career changer B?

A: Not required, but career changer B invested 6 million won in additional mentoring. This was necessary because existing marketing experience needed to be "translated" into development language. College student A and employed developer C succeeded with only free AI coaching. Conclusion: Additional investment is efficient only when development fundamentals are weak.

Q3: Can I get ROI even while working like employed developer C?

A: Yes. Employed developer C's case proves it. With just 15 monthly hours (3.5 hours per week) of low-intensity study, she generated 2–3 million won monthly external freelancing revenue within 3 months. The key is learning a "new technology stack" while combining it with existing job experience. In this case, ROI appears even higher because initial investment is minimal.

The insights from these 3 scenarios—from inexperienced college students to career changers to employed professionals—are clear. Because Careeron's free mobile app has zero initial investment, any recovery value automatically yields ROI of at least 300% or higher. College student A gained 36 million won in value through internship position acquisition (ROI 1,700%), career changer B clarified her tech transition path after 6 months of investment (expected ROI 304%), and employed developer C generated 2–3 million won monthly external revenue within 3 months (ROI 1,200%).

What matters is that the recovery method varies completely depending on investment time and background. Time-rich college students achieved fast position acquisition, career changers needing tech transition built credibility through diverse portfolios, and already-employed individuals gained immediate income increase and career acceleration.

A free mobile app isn't "cheap" because of its price—the core is eliminating entry barriers and proving ROI through actual deliverables. SB Consulting's CEO Shim Jae-woo emphasizes, "The moment inexperienced job seekers secure competitiveness with their first project and immediately recover it through salary, freelancing, or promotion points is exactly when a free platform delivers maximum value."

Regardless of your background, if you download Careeron's free mobile app today and start your first project, you'll be in a completely different career position 3–6 months from now. For additional consultation, contact 01023975734 or jaiwshim@gmail.com.
