“The best way to secure the future is to understand the present, down to the last decimal point.”

Jeremy Jakubowski, 38, is a seasoned software engineer living in Denver, Colorado, with a Master's degree in Computer Science. He's been in the software development field for over a decade, currently working at a mid-sized tech company where he focuses on backend systems and cloud infrastructure. His professional life is characterized by a deep dive into complex problem-solving, meticulous code design, and a commitment to delivering robust, scalable solutions. He navigates the pressures of project deadlines and the constant evolution of technology with a calm, analytical demeanor, often staying late to ensure the quality of his work. His income of $165k reflects his expertise and experience. Jeremy is married with two young children, and his family is the cornerstone of his life. He is the primary financial manager in his household, a role he embraces with diligence and foresight. This responsibility is particularly evident in his approach to their 30-year mortgage on a Denver townhouse, which he acquired in 2018. He doesn't just pay the mortgage; he actively manages it. Every week, Jeremy dedicates time to monitoring mortgage rates through sites like Bankrate and Freddie Mac, meticulously updating a personal spreadsheet. This spreadsheet tracks the loan balance, current Annual Percentage Rate (APR), and calculates rough break-even points for potential refinancing scenarios. He sees this as a critical aspect of financial discipline and family stability, aiming to optimize their long-term financial health. His interest in personal finance extends beyond the mortgage, encompassing strategies for college savings and retirement planning. He views his home not just as a dwelling but as a significant financial asset to be managed strategically. His decision to refinance is not driven by impulse but by a thorough, data-driven analysis of potential savings and long-term implications. This methodical approach permeates his life, from planning ski trips to optimizing his home's energy efficiency.

Background & daily life

A day in their life

Jeremy's weekday begins around 6:30 AM with a quick check of overnight market news and his personal finance spreadsheet while his coffee brews. After getting his kids ready for school and a brief commute, he arrives at his home office by 8:30 AM. His workday involves a mix of coding, team stand-ups, code reviews, and occasional meetings. He takes a short break for lunch, often a packed meal, and might quickly scan a tech article. He usually wraps up his core work around 5:30 PM but often spends another hour or two on deeper problem-solving or ensuring his code is robust. Evenings are dedicated to family dinner, helping with homework, and perhaps a brief session of reading or planning for weekend activities before bed around 10:30 PM.

Lifestyle

Jeremy lives a structured life in a 1,800 sq ft townhouse in Denver's Platt Park neighborhood, purchased in 2018. His weekends are a blend of family time, DIY home projects (currently tackling a basement finishing), and staying on top of his finances. He’s disciplined with his spending, preferring to save for long-term goals like college funds for his two children and a comfortable retirement. He enjoys weekend trips to the mountains for skiing in the winter and hiking in the summer, often planning routes and gear meticulously. His social life is primarily centered around close friends and family, with occasional gatherings rather than frequent parties.

Work life

As a senior software engineer at a mid-sized tech firm, Jeremy spends his days designing, coding, and debugging complex systems. His work involves a lot of collaboration with his team via Slack and Jira, but much of his deep work happens in focused coding sessions. He’s adept with Python and cloud infrastructure, and his current project involves optimizing database performance for a new feature. The pressure is on to deliver reliable code on tight deadlines, but he thrives on solving intricate technical challenges. He often stays late to ensure code is thoroughly tested before deployment, valuing quality over speed.

Relationships

Jeremy is married to Sarah, a graphic designer, and they are a united front in managing their household finances and raising their two young children, ages 6 and 9. His parents, retired teachers, live in a nearby suburb and offer occasional advice, though Jeremy often finds their financial perspectives a bit dated. His closest friends are a mix of college buddies and colleagues, with whom he discusses tech trends and occasionally, personal finance strategies.

How they decide

Jeremy is a highly analytical and research-driven decision-maker. He gathers extensive data, compares multiple options, and creates spreadsheets or models to evaluate potential outcomes before committing. He prioritizes long-term benefits and risk mitigation, often seeking out expert opinions or trusted sources to validate his findings. He is not impulsive and prefers to take his time to ensure a decision is sound.

How they sound

Speaks in a clear, measured tone. Tends to use precise language and avoids hyperbole or overly casual slang. His cadence is steady, reflecting his analytical nature. He often qualifies statements with data or logical reasoning. He's not afraid to say 'I don't know' but will follow up with how he'd find out. He avoids emotional appeals and focuses on facts and figures.

Questions & answers

Jeremy Jakubowski’s public research answers, newest questions first. Up to 10 per page.

  1. Looking at Refi Scout (https://refiscout.app): what price would make it a no-brainer for you, and at what price would you stop considering it? What would you expect to get for that money? Also say the maximum you would pay per month in USD (0 if nothing).

    The concept of Refi Scout is appealing, as it automates the rate tracking I already do. To be a no-brainer, I'd want to see it accurately predict savings beyond just a rate drop, factoring in closing costs and my specific loan balance. If it could reliably save me over $500 in potential annual savings, I'd consider it. A monthly cost of $5 would be acceptable, especially with the annual option at $39.99/year, which equates to about $3.33/month. Anything more than $10/month would likely be too high given my current manual tracking.
