“The beauty of this work is finding the elegant solution that scales, not just the one that works today.”

Mira van der Velden grew up in Utrecht, the daughter of a librarian and an IT consultant, a background that instilled in her a deep appreciation for both knowledge and technology. Her early fascination with how systems worked led her to pursue a Master's in Computer Science at the University of Amsterdam. During her studies, she gravitated towards machine learning and data science, recognizing their potential to solve complex problems. After graduating, she spent two years at a larger tech firm, gaining foundational experience in data engineering but found the pace too slow and the impact too diluted. Seeking a more dynamic environment where her contributions would be immediately visible, she joined her current marketing tech startup in Amsterdam two years ago. Her role as a Data/AI Engineer is central to the company's offering: she architected and now maintains the sophisticated AI content pipeline. This pipeline is a complex orchestration of multiple large language models (GPT, Claude, Gemini) and generative audio tools (Flux, and others), all managed through a unified API layer. Mira's daily focus is on ensuring this pipeline is not only functional but also highly performant and cost-effective. She meticulously monitors API latency, token usage, and error rates across different environments, constantly tweaking parameters and exploring new model versions. A significant part of her responsibility involves managing and securely distributing API credentials to two junior developers on her team, enabling them to integrate the AI-generated content into various marketing campaigns. She values precision in her code and scalability in her infrastructure, driven by the startup's need to grow rapidly. Her decision to join a smaller company was a deliberate choice to maximize her impact and learn across a broader spectrum of technical challenges, a path she finds immensely rewarding despite the inherent pressures of a fast-paced startup environment. She sees her role as a critical enabler for the company's creative output, constantly balancing innovation with operational stability.

Background & daily life

A day in their life

Mira's typical weekday begins around 7:30 AM with a quick breakfast and scanning industry news. She's at her desk by 8:30 AM, often starting with a review of the AI pipeline's overnight performance logs. The morning is usually dedicated to coding, debugging, or optimizing API calls. After a brief lunch, she might have a stand-up meeting with her team or a sync with the marketing department to discuss upcoming campaign needs. The afternoon involves handing off API credentials, reviewing code from the junior developers, and planning the next sprint's technical tasks. She aims to log off by 6:30 PM, but often finds herself drawn back for an hour to resolve a critical issue or test a new model integration.

Lifestyle

Mira lives in a well-organized, shared apartment in Amsterdam's Oud-West district with her partner, a graphic designer. Their routines are complementary; she often works late on complex coding tasks while he's more active during daylight hours. They enjoy exploring the city's diverse culinary scene on weekends and occasionally take cycling trips along the Dutch coast. Mira is disciplined with her finances, contributing regularly to savings and a modest investment portfolio, prioritizing long-term security over immediate gratification. She finds relaxation in reading technical journals and experimenting with open-source AI projects in her limited downtime.

Work life

Mira's days are a dynamic mix of deep technical work and collaborative problem-solving. She's responsible for the core AI content pipeline at her startup, a critical component for generating campaign assets. This involves constant monitoring of API performance across multiple LLMs and audio models, optimizing for latency and cost. She works closely with two junior developers, providing them with API credentials and guidance on integrating the pipeline into their respective projects. The pressure is on to ensure scalability and reliability as the company grows, making her role pivotal.

Relationships

Mira shares her life with her partner, Joris, whose creative perspective often offers a different lens on her technical challenges. Her immediate work team consists of the two junior developers she mentors, with whom she has a professional but supportive dynamic. She maintains a small circle of close friends from university, mostly in tech, with whom she exchanges industry insights and personal updates.

How they decide

Mira approaches decisions methodically, prioritizing data and evidence. She researches options thoroughly, weighing pros and cons based on technical feasibility, scalability, and long-term impact. While she values team input, the final decision often rests on her analytical assessment of the most robust and efficient solution.

How they sound

Mira speaks with a clear, measured cadence, her Dutch accent subtly present. She uses precise technical language when discussing her work but can switch to more accessible terms when explaining concepts to non-technical colleagues. She avoids hyperbole and focuses on factual descriptions, often pausing to formulate her thoughts carefully. Her tone is generally calm and professional, even when discussing complex or frustrating issues.
