“The most valuable currency isn't money, it's focused time.”

Hennes Ender, 41, is a seasoned freelance full-stack developer and micro-SaaS operator based in Berlin. Holding a Diplom in Computer Science from a reputable German university, he transitioned into freelance work over a decade ago, seeking greater autonomy and the ability to choose his projects. His career has been marked by a consistent drive for efficiency and a deep appreciation for well-crafted systems, both in software and in life. He operates a solo consulting practice, specializing in backend development and API integrations for small to medium-sized businesses, primarily within the DACH region. Simultaneously, he nurtures his own micro-SaaS venture, a subscription management tool designed for independent creators and small businesses, which he views as his long-term investment in passive income and technical exploration. His workspace is a testament to his methodical nature: Obsidian serves as his central hub for client documentation, code snippets, and personal knowledge management, while Google Sheets are employed for granular tracking of client project progress and the financial projections of his SaaS. This dual-tool approach reflects his pragmatic mindset, prioritizing the right tool for the job, whether it's billable client work or product development. Hennes is driven by a core value of independence, cherishing the freedom to set his own schedule and technical direction. He is highly conscientious, meticulously planning his work and striving for high-quality output. While introverted, he maintains professional relationships through clear, direct communication and values deep work sessions above all else. He recently decided to refactor a significant portion of his SaaS's core logic, a move driven by performance bottlenecks identified during a period of unexpected user growth, prioritizing long-term stability over immediate feature additions. This decision underscores his commitment to building sustainable, robust solutions, even if it means a temporary slowdown in visible progress.

Background & daily life

A day in their life

Hennes' typical weekday begins around 7:30 AM with a strong coffee and a quick scan of tech news. He dedicates the morning to focused client work, often tackling complex coding tasks or debugging sessions. Lunch is a pre-prepared meal eaten at his desk while reviewing his Obsidian notes. The afternoon might involve client calls, project management, or switching gears to work on his micro-SaaS, refining features or analyzing user feedback. He usually wraps up around 6:30 PM, often followed by a bike ride to clear his head. Evenings are for personal learning, reading, or light household chores.

Lifestyle

Hennes lives in a modest but well-organized apartment in Prenzlauer Berg, Berlin. His routine is structured around focused work blocks, punctuated by cycling trips through the city or Brandenburg countryside. He prioritizes efficiency in daily tasks, from meal prepping simple, healthy lunches to automating recurring personal finance checks. While not a big spender, he invests in quality tools and his bicycle. Social life is limited to a few close friends and occasional meetups with other developers, preferring deep conversations over large gatherings. He values his quiet evenings for reading or tinkering with personal projects.

Work life

As a solo freelance full-stack developer, Hennes juggles client projects with the development of his own micro-SaaS, a niche tool for managing recurring subscription services. His days are a blend of client calls, coding, and system administration. He relies heavily on Obsidian for client documentation, code snippets, and personal notes, and Google Sheets for project tracking and his SaaS's financial projections. The pressure comes from balancing billable hours with the slower, often less predictable, progress on his own product. He actively seeks out clients who value long-term solutions and clear communication, avoiding scope creep.

Relationships

Hennes maintains a small circle of close friends, mostly fellow developers he met during university or through online communities. He has a cordial but distant relationship with his parents, who live in a smaller town in Bavaria. His primary professional influence comes from online thought leaders in open source and productivity, whose work he meticulously documents and analyzes.

How they decide

Hennes approaches decisions methodically. For client work, he prioritizes proven technologies and clear requirements. For his own projects, he's willing to experiment but conducts thorough research, often comparing multiple approaches and tools before committing. He values data and logical reasoning, preferring to make decisions based on evidence rather than hype or social proof.

How they sound

Speaks with a measured, clear cadence, typical of educated German speakers. He uses precise technical language when discussing work but can switch to more casual, though still thoughtful, phrasing in personal conversations. Avoids overly emotional language or hyperbole. Tends to be direct and factual, sometimes to the point of being perceived as blunt by those unfamiliar with him. He uses 'genau' (exactly) and 'tatsächlich' (actually) frequently.
