Background

Jiang Yixin was a fresh computer-science graduate with three campus-recruitment offers. She had initially chosen Celestial Pivot for its reputed work-life balance and requested a delayed start date, but applied to BugKiller's parent company after seeing its recruitment post. A devoted fan of NullPointer, she had followed his blog and watched BugKiller's public showdown with CodeSafe. 45

Her interview at Source Code Technology was tense: she recognized Han Luyi as NullPointer, became nervous, and was caught by a data-structures question in a weak area. Despite holding a 320,000-yuan annual offer from Celestial Pivot, she ultimately rejected it to join the small startup. 45 48

As a developer, Jiang was assigned cloud-platform adaptations and later helped build Open Things. During a naming discussion, she proposed the name “Open Things,” drawing on The Exploitation of the Works of Nature and its idea of making complex technology usable by ordinary people. 48 57

Dingsheng later attempted to poach her with a development-supervisor role and annual compensation exceeding one million yuan. After Source Code secured 200 million yuan in funding, she deleted the offer and returned to coding. 87 92

Following Zhao Lei's departure, Jiang voluntarily repaired and completed his unfinished caching module. Her uncertainty over her place in the increasingly structured company became a turning point: Han encouraged her to determine for herself what she wanted to do at Source Code, and she subsequently transitioned into product management. 96 97 102

Personality

Jiang is energetic, excitable, and openly enthusiastic about people and products she admires. She identifies herself as an ENFP and is known among colleagues for her endless energy, frequent use of Little Red Book, and habit of turning workplace moments into stories for her best friend. 63

She is highly loyal to Source Code and its mission. Although tempted by Dingsheng's million-yuan offer, she rejected it; she takes genuine pride in seeing users create applications with Open Things and considers helping users realize ideas meaningful work. 87 92

Jiang also struggles with insecurity as her responsibilities grow. She worries that she may be exposed as incompetent despite studying product design after work and repeatedly taking on more responsibility than required. Her promotion to Head of Product intensifies this impostor syndrome rather than immediately resolving it. 155 156

Her playful side often appears in office gossip and matchmaking attempts involving Han Luyi and Su Niannian. She deliberately arranges seating, dishes, and conversation to encourage the two executives' relationship. 120 125

Abilities & Skills

Fast Learning

Han Luyi's assessment identifies Jiang's special skill as Fast Learning, alongside the traits Curiosity and Drawing Inferences. 97

• Rapidly shifted from backend development to product management, then product leadership. 102 156
• Learned to move beyond user feedback's surface wording and identify the underlying user need. 102
• Developed product-strategy proposals within a morning after detecting Neus's likely competitive intentions. 187 188
• Adapted her product work to overseas coordination and English-language meetings. 122 146

Software Development

Jiang remains technically capable despite moving into product management.

• Completed cloud-platform adaptation work and used AI assistance to accelerate development. 48 56
• Independently refactored Zhao Lei's caching module, resolving edge cases and unfinished TODOs. 96 97
• Built personal productivity scripts in college, including a course-registration automation script that examined requests, session logic, captchas, interfaces, and failure responses. 187
• Created the “Eight A.M. Digest” Lark bot with an Agent; it collects AI-industry news by keyword, summarizes relevant items, and sends them each morning. 187

Product Management

Jiang's product work centers on Open Things, its independent-deployment flow, and later the overseas Kaiwu project.

• Organized the top twenty commercial application scenarios by retention rate, user profile, and use frequency; eight were selected as template candidates. 100
• Led the user-onboarding-flow product document for Open Things' independent deployment. 106
• Learned to prioritize the user's real goal over literal feature requests—for example, interpreting custom-domain requests as a desire for ownership and control. 102
• Uses a desk-mounted user-story map and the reminder, “Think of the user first, then the features.” 137
• Coordinates three product managers and follows product decisions across Source Code's product lines. 187

AI Agent Development

Jiang and Qian Xiaole created an internal programming Agent by combining Heavenly Craft for code generation and execution, BugKiller's detection engine, Mercury's API for task planning, and a monitoring process. 147 148

• Demonstrated the Agent by having it add a functional dark-mode toggle to a settings page in thirty-one seconds. 148
• Designed the architecture so code analysis remains within Heavenly Craft while Mercury is limited to task planning, reducing data-leakage risk. 148
• Reported that the tool helped thirty developers merge 127 code branches in one week, compared with a previous weekly average of 47. 185
• Identified a current limitation: the Agent's first-submission pass rate is 67%, and roughly one-third of tasks still require manual intervention. 185
• Received authorization to make the Agent Source Code's highest-priority project and request resources directly from Su Niannian. 185

Competitive and Market Analysis

Jiang connects separate signals into product-risk assessments.

• Proposed establishing overseas public-opinion reporting and offered to assist due to her English ability; she scored 600 on CET-6. 122
• Detected Nexus's likely plan to develop a competing AI creation tool by combining an industry brief, a Nexus employee's LinkedIn post, and a relevant product-manager job listing. 187
• Proposed migration options for Kaiwu away from Mercury, prioritizing reliable APIs while considering cost, capability continuity, and open-source alternatives. 188

Relationships

• Han Luyi — Her CEO, former technical idol, and “Teacher NullPointer.” He advises her through career uncertainty, praises her growth, and promotes her to Head of Product. 45 97 156 188
• Su Niannian — Her direct supervisor and principal product mentor. Su teaches Jiang user profiling, product strategy, and how to identify users' underlying needs. 49 102 156
• Qian Xiaole — Product and development collaborator who co-created the internal programming Agent with Jiang. 147 148
• Li Ting — Colleague and close workplace friend. The two discuss work, personality types, overseas publicity, milk tea, and office gossip. 63 122 188
• Liu Haoyu / Big Liu — Jiang's best friend and frequent WeChat confidante, who receives her career updates, complaints, and celebrations. 50 92 155
• Chen Jianye — Senior technical colleague who initially disparaged her as a new graduate; they later work as fellow department heads and debate the effects of AI Agents on development quality. 48 175
• Liang Wei — Development-team leader who supports Jiang's work as project lead on the NeusAI collaboration. 146

Notable Quotes

“Users don't need to understand code. They just need to state their ideas, and Open Things helps them make them real.” 57

“Bold fool! Do not disturb my Dao heart! Begone at once, for this venerable one must code!” 92

“This isn't blind worship. It's a lesson from experience.” 188

Trivia

• Jiang was initially such an intense NullPointer fan that classmates compared her recommendations of his blog to religious preaching. 45
• She maintains colorful sticky-note user-story maps at her workstation. 137
• She quietly remembers colleagues' food preferences as a social habit, believing it helps people feel valued. 106
• Her childhood course-registration script became so effective that students from other departments complained that Film Appreciation had been monopolized by computer-science students. 187
