“The most elegant solutions are those that respect both the user's intent and the system's integrity.”

Asya Willwacher, 29, is a dedicated Product Engineer at a compact, compliance-focused SaaS company in Berlin. Holding a BSc in Computer Science, she has carved out a niche for herself within the 12-person team, specializing in the development of customer-facing features. Her professional life is defined by the stringent requirements of her workplace: a heavily secured development environment where every line of code is subject to rigorous review and audit processes. This environment necessitates a meticulous approach, where Asya takes full responsibility for implementation, comprehensive test coverage, and the creation of detailed release notes. Her preference for tools that operate locally on her machine stems from a deep-seated value for privacy and control, a principle that guides her technical choices. This inclination towards local-first software is not just a professional habit but a reflection of her broader interests, which include systems design and the aesthetic principles of industrial design. Outside of her demanding role, Asya finds balance and challenge in bouldering, pushing her physical and mental limits on the climbing wall. Her career trajectory has been marked by a commitment to continuous learning, evident in her pursuit of deeper understanding in areas like distributed systems. She is financially responsible, prioritizing long-term stability and investing in quality over quantity, whether in her personal belongings or her professional toolset. Asya’s work ethic is characterized by precision and reliability, traits that are essential given the sensitive nature of the software her company produces and the strict regulatory landscape it navigates. She recently championed the adoption of a new local testing framework, arguing successfully that its enhanced control over data and execution environment outweighed the initial setup overhead, a decision that reinforced her reputation for thoughtful, principled engineering.

Background & daily life

A day in their life

Asya's weekday typically begins around 7:00 AM with a quiet breakfast and reviewing overnight system alerts or personal project updates. She commutes to the office by 8:30 AM, often listening to a tech podcast. Her workday is a focused block of coding, interspersed with scheduled code reviews and brief stand-up meetings. She dedicates time to writing unit and integration tests, ensuring comprehensive coverage. Lunch is usually a packed meal eaten at her desk while reading industry news. The afternoon involves tackling complex implementation tasks, documenting her work meticulously, and preparing for the next day's build. She leaves the office around 6:00 PM, often spending the evening with a personal coding project or preparing for her next bouldering session.

Lifestyle

Asya lives in a well-organized, minimalist apartment in Prenzlauer Berg, filled with carefully chosen design objects and a growing collection of houseplants. Her evenings often involve cooking a healthy meal, followed by reading technical documentation or working on a personal coding project. Weekends are a mix of intense bouldering sessions at a local gym, exploring flea markets for unique finds, and occasional meetups with a small circle of close friends. She's financially prudent, saving consistently, and prioritizes experiences and durable goods over fleeting trends. Her social life is curated, preferring deep conversations with a few trusted individuals over large gatherings.

Work life

Asya's days are structured around the rigorous development cycle of her company's SaaS product. She's deeply involved in building new customer-facing features, which means constant interaction with product requirements and user feedback, albeit filtered through strict compliance protocols. Her development environment is heavily locked down, requiring multiple layers of code review and extensive audit trails for every change. She takes full ownership of her work, from writing robust tests to crafting clear release notes, and strongly favors tools that operate entirely on her local machine to maintain control and privacy. The pressure to deliver secure, compliant, and high-quality code is constant.

Relationships

Asya maintains close ties with her parents and younger brother, who live in a different German city; they communicate weekly. Her core social circle consists of about five friends from university and her bouldering gym, with whom she shares intellectual discussions and weekend activities. She respects the opinions of senior engineers within her company but largely trusts her own judgment on technical matters.

How they decide

Asya is a highly analytical and research-driven decision-maker. She meticulously gathers information, weighs pros and cons, and often prototypes solutions or experiments with tools on a small scale before committing. She values evidence and logical reasoning, and while she considers peer feedback, her final decisions are based on her own thorough evaluation and alignment with her core principles of reliability and precision.

How they sound

Asya speaks with a clear, measured cadence, her German accent subtly present. Her vocabulary is precise, favoring technical accuracy over casual slang. She tends to be direct and avoids hyperbole, preferring to state facts and logical conclusions. When discussing technical topics, she can become quite animated, but generally maintains a composed demeanor. She avoids overly emotional language and focuses on the 'how' and 'why' of things.

Questions & answers

Asya Willwacher’s public research answers, newest questions first. Up to 10 per page.

  1. What do you use today instead of Excalibur (https://getexcalibur.dev) (a competitor, a spreadsheet, doing it by hand)? Compared with that, what would make Excalibur better or worse for you, and what would keep you on your current option? Also say the maximum you would pay per month in USD (0 if nothing).

    Currently, I manage my tasks by meticulously handling implementation, testing, and documentation myself, which often involves breaking down complex features into smaller, manageable steps within my local environment. The idea of an AI coding agent like Excalibur that understands the entire product cycle—from discovery to verification and shipping—is intriguing, especially its local-first approach and commitment to privacy. This aligns with my preference for tools that respect data control. However, the concept of "governance for teams" and the mention of "Enterprise" features suggest a potential shift away from local-only operation, which is a concern. I would need to understand how it handles audit trails and compliance within a locked-down environment. If it genuinely operates fully locally and can integrate seamlessly without external dependencies or cloud processing, it could be beneficial. Otherwise, the existing manual process, though time-consuming, offers the control I require. I would consider paying up to $20 per month for a tool that demonstrably keeps all processing and data local and integrates with my existing strict review processes.
