About

Hello, I’m Mark. I care about readable code, performance, and delivering reliable products end to end. I partner closely with stakeholders to cut scope smartly and ship on time. My bias is toward pragmatic solutions that scale as needs grow.

I’ve worked across childcare, healthcare, finance/crypto, and telecom companies, helping teams design and deliver reliable, scalable web applications. My focus is on clear architecture, practical tradeoffs, and smooth end‑to‑end experiences. From internal tooling to customer-facing flows so products ship confidently and grow gracefully.

Welcome and thanks for stopping by. Feel free to explore my work, and reach out if something sparks an idea.

Side Projects

• V60 Brewing Calculator

  Built a simple brewing calculator for the famous 4:6 pour-over method. Allows flexible adjustments based on taster's preference.

• My Ride Log

  Built a one-pager visualization of my cycling workouts where I get to see different data points about my training. Main purpose for making this is mostly for motivating myself to train regularly and take fitness seriously.

• Lolpedia

  I watch pro games of `League of Legends` and often get to a point where I don't know stuff. What does this `champion` do? What's the use of this `skill`? How does this `item` work? By using their API, I've built an app that allows me to answer all these questions.

• Jimny Maintenance Help

  I own a Jimny and had a few difficulties in the past figuring out which part(s) need checking or replacing based on mileage. This web app (which is based on the official car manufacturer's booklet) allows me to figure this out, and with so much ease.

• Axie Scholar Management

  Made my own management tracker during the good days of the game `Axie`. I have a few players working for me and this app enables me to manage and know how much to pay them accurately and on-time.

• COVID-19 Daily SMS Alerts

  During the COVID-19 pandemic, I had to build a tool that reports COVID-19 numbers daily through SMS. While I don't particularly think this was helpful for some people, I'm more than happy enough to have helped a few people receive the reports.
