A personal blog and project portfolio by jiajie, a software engineer with a background in graphics and special effects rendering transitioning into a Forward Deployed Engineer (FDE) role within the education sector. The site features projects such as 100-minds (a cross-disciplinary mental model knowledge base) and weread-wise (an AI-driven reading assistant), alongside reflections on LLM concepts, systems thinking, and professional growth.

What's inside jiajie

  1. Overview of weread-wise intelligent reading assistant

    weread-wise is a tool designed to connect the process of selecting books with the process of retaining knowledge. It focuses on two primary functions: goal-driven book recommendations (mapping a user's goal to a specific set of books) and the unified accumulation of reading notes by aggregating highlights and comments from WeChat Reading into a thematic knowledge graph.

  2. Use Trae for AI-driven code editing and text manipulation

    Trae is an AI-powered code editor suitable for any task involving text character modification. Beyond coding, it can be used for writing, generating flowcharts (via text-to-chart tools), and knowledge Q&A to improve overall productivity.

  3. Technical architecture of weread-wise

    The weread-wise system is built using the following technical stack and logic:

    • Tech Stack: LangChain, MiniMax M2.5, and MiniMax Speech.
    • Recommendation Layer: Uses LLMs to decompose goals into a capability map, employs embedding retrieval and topic modeling for candidate recall, and utilizes a ReAct Agent to explain the reasoning behind recommendations.
    • Accumulation Layer: Pulls notes via the WeChat Reading skill, uses LLMs for topic clustering and concept extraction, and stores the results in a local knowledge base.
    • Interfaces: Planned for CLI and Web access.

  4. Use Markdown for structured content and AI interaction

    Markdown is a lightweight markup language used to create structured documents without complex formatting. It is highly recommended for developers and AI users because it is one of the most mainstream input formats for Large Language Models (LLMs), reducing the friction when interacting with AI tools.

  5. Understand the Money Spectrum framework

    The Money Spectrum is a conceptual model used to analyze an individual's relationship with money and how it reflects their identity and values. It posits that a person's attitude toward wealth evolves through three primary stages: Survival, Freedom, and Power. This is not a set of absolute categories but a spectrum where individuals can slide between stages or share characteristics of multiple stages depending on their current financial state and psychological needs.

  6. Understanding the Forward Deployed Engineer (FDE) role

    A Forward Deployed Engineer (FDE) is a software engineer who operates at the intersection of product engineering and the customer's real-world environment. Unlike traditional product engineers who build a single feature for many customers, an FDE focuses on a specific customer to combine multiple capabilities and solve their most complex, immediate problems. They are responsible for bringing product capabilities into real-world scenarios and feeding field experience back into the product system.

  7. Implement a Personal Board of Directors for personal growth

    The 'Personal Board of Directors' is a concept introduced by Jim Collins. It involves curating a mental group of role models—people who possess the skills, attitudes, or character traits you wish to acquire—to serve as a benchmark for your own growth and decision-making.

    Key principles for managing your board include:

    • Selection Criteria: Members do not need to be perfect or share your exact worldview. Focus on specific areas where they excel (e.g., high achievement, noble character, or a specific skill) and ignore their flaws.
    • Dynamic Membership: The board is not static. You should rotate members based on your current needs (e.g., switching from a 'peacetime' advisor to a 'wartime' strategist) or replace a member once you have learned everything they have to offer.
    • Raising Standards: Use the high standards of masters to challenge your own. For example, adopting Charlie Munger's standard of not expressing an opinion unless you understand the opposing argument better than the opponent.
    • Measuring Success: The board provides a scale to measure your actions, but the goal is not to compete with the role models. The only true competitor is your past self; success is defined as being slightly better today than yesterday.

  8. Understand the role of a Forward Deployed Engineer (FDE) in AI implementation

    A Forward Deployed Engineer (FDE) focuses on the practical application of AI within a client's business environment. Rather than just coding, the FDE handles complex high-level judgments and operational challenges, including:

    • Determining if a problem is worth solving.
    • Deciding how to modify business processes.
    • Designing evaluation standards for AI performance.
    • Managing organizational resistance to change.
    • Defining security boundaries.
    • Abstracting field experience into scalable product capabilities.

  9. Adopt the 'CEO of Self' mindset for knowledge work

    The transition from manual labor to knowledge work requires a fundamental shift in management: the individual must move from following instructions to becoming the 'CEO' of their own professional life. This 'self-management' is necessary because the traditional assumptions of the industrial age—that organizations outlive employees and that employees remain in one place—are no longer true. Knowledge workers now typically outlive their organizations and possess higher mobility, making self-directed management of their skills, values, and career paths a requirement for success.

  10. Manage your career as a 'CEO of One'

    In the modern knowledge economy, organizations no longer plan career paths for employees. Individuals must take full responsibility for their own professional development. This requires a deep understanding of:

    • Personal strengths and weaknesses
    • Learning styles (how you acquire new knowledge)
    • Work methods (how you actually get things done)
    • Core values
    • Areas of maximum contribution

  11. Adapt learning strategies to the trend of knowledge explosion

    Scientific knowledge is estimated to double approximately every 17 years, leading to rapid specialization and the emergence of thousands of distinct professional fields. To remain effective in a technical career, practitioners must focus on 'meta-education' (learning how to learn) to develop the ability to acquire new skills quickly and adapt to shifting technological landscapes, rather than relying solely on static traditional education.

  12. Distinguish between Goal-oriented and System-oriented approaches

    The author argues that a system-oriented approach is more effective for long-term success and happiness than a goal-oriented one.

    • Goals are specific outcomes you hope to achieve in the future. They often lead to a persistent feeling of failure until the goal is reached, and a sense of emptiness or lack of direction once achieved.
    • Systems are regular, repeatable actions or processes that you perform consistently. They provide immediate satisfaction and a sustainable path toward improvement without a fixed deadline.

    Comparison Examples:

    • Weight Loss: Losing 10 lbs is a goal; maintaining a healthy diet is a system.
    • Fitness: Running a marathon in 4 hours is a goal; exercising daily is a system.
    • Business: Earning $1 million is a goal; becoming a serial entrepreneur is a system.
