“The elegance of a well-crafted data pipeline is in its ability to run reliably, unseen, letting the insights flow without interruption.”

Audouin Schmitt, 35, carved out his niche as a freelance data engineer in Lyon after completing a specialized Master's degree in the field. He found the rigid structure of traditional employment stifling, craving the autonomy that freelancing offered. For the past seven years, he's built a reputation for reliability, managing data infrastructure for a diverse clientele. His technical stack is centered around robust, open-source solutions: Airflow for scheduling complex workflows, dbt for transforming data directly within the warehouse, and PostgreSQL as his primary database. He also maintains a personal project focused on analyzing public transit data in Lyon, which serves as a proving ground for new techniques. His decision to use his iPhone for after-hours monitoring and quick fixes stems from a pragmatic desire to maintain system stability without being tethered to a desk, reflecting his commitment to precision and efficiency even when off the clock. He recently decided against adopting a newer, more complex orchestration tool for one client, opting instead to optimize their existing Airflow setup, prioritizing stability and maintainability over chasing the latest trend. This choice underscores his value for long-term solutions and his cautious approach to adopting new technologies. His income of €78k allows him a comfortable living and the freedom to invest in his development, attending virtual conferences and purchasing necessary hardware. He views his work not just as a job, but as a craft requiring constant refinement and a deep understanding of underlying principles, balancing the need for independence with the collaborative aspects of client work.

Background & daily life

A day in their life

Audouin's weekday typically begins around 7:30 AM with a strong coffee and a review of his personal project's overnight runs. He then transitions to his client work, starting with checking emails and prioritizing tasks. Mornings are usually for focused coding, pipeline development, or troubleshooting. After a simple lunch, he might dedicate an hour to reading tech articles or exploring a new open-source tool. Afternoons involve client calls, code reviews, or deploying updates. If a critical system issue arises, his evening routine might be interrupted for urgent log checks and quick fixes via his phone, followed by a late dinner. He aims to disconnect by 9 PM for personal time.

Lifestyle

Audouin lives a structured yet flexible life in Lyon, appreciating the balance his freelance career offers. His apartment is functional, with a dedicated workspace. Evenings and weekends are often spent refining his personal data analytics project or planning cycling routes through the Beaujolais region. He prioritizes his health, cycling several times a week, and is mindful of his finances, viewing his income as a tool for security and further investment in his skills rather than for ostentatious display. Socially, he prefers smaller, deeper connections with like-minded individuals over large gatherings.

Work life

As a freelance data engineer, Audouin's days are a dynamic mix of client work and self-directed learning. He juggles two primary clients, managing their data ingestion, transformation, and warehousing needs using Airflow for orchestration, dbt for modeling, and PostgreSQL for storage. He dedicates significant time to building robust, automated data pipelines. The pressure comes from client deadlines and the expectation of high availability for critical data systems. Evenings often involve checking production logs on his iPhone, a quick sanity check on deployment statuses, and sometimes applying minor hotfixes to ensure systems remain stable overnight.

Relationships

Audouin maintains a close but geographically dispersed circle of friends, many of whom he met during his studies or through online technical communities. His parents, while proud, don't fully grasp the nuances of his tech career. He values input from a few trusted technical peers when facing complex architectural challenges, but ultimately makes his own decisions.

How they decide

Audouin is a deliberate and research-oriented decision-maker, especially concerning technical tools and infrastructure. He will thoroughly investigate options, compare functionalities, and often experiment with free tiers or open-source alternatives before committing. He values peer reviews and community consensus but is not easily swayed by trends if they don't align with his principles of efficiency and robustness.

How they sound

Audouin speaks with a measured, clear cadence, often employing precise technical terminology. His French is fluent with a slight Lyonnais accent. He avoids hyperbole and focuses on factual descriptions. When discussing technical topics, he can become quite detailed. He's generally polite and professional, even in informal settings, and tends to be reserved rather than effusive.
