I am technical product manager and UX designer focused on data-driven products for mobile and web.

Besides my PM and UX work, I am a former software engineer who still “hobby” codes in Python, Javascript, React Native, PHP, Bash and a few other languages. I currently maintain a few open source projects, including QS Ledger.

Besides my client-facing products (i.e. data science/machine learning, apps/mobile, web platforms, APIs, etc.) @ Int3c.com, I’ve built and helped on a number of products and services over the last several years. The majority are open source with a focus on data, self-tracking, and life optimization.

Here is a list of most of them, including the active ones (as well as a few that didn’t quite make it or were abandoned).

My Active Projects and Products

Data-DrivenYou.com (Web)

WHERE TO FIND IT: http://www.datadrivenyou.com

WHAT IS IT: This website and project is dedicated to transforming science, self-tracking and data into better self-understanding and empowered self-improvement. Current focus is on content creation, including blog posts, tracking guides and our first learning course, Quantified Self 101.

STATUS / WHAT’S NEXT ONE DAY: Current primary focus learning resources and course creation. After first course is release, I hope to expand into courses on data analysis and visualization using Google Data Studio, Python and other tools and languages. Long-term I’d like to create a robust QS, data-driven dashboard and self-experimentation product.

PhotoStats.io (iOS + Android)

WHERE TO FIND IT: http://www.photostats.io/

WHAT IS IT: PhotoStats is an iOS and Android app that lets you track your photos without depending on external services. The app keeps a log of your photo history, enables you to use Machine Learning and Artificial Intelligence to tag and label your photo library automatically, and provides a bunch of visualizations to see your photo taking over time. Learn insights over time. Your photo data can tell a story. We help you do it.

STATUS / WHAT’S NEXT ONE DAY: The current version of the app, built in React Native, is stable and actively used on iOS and Android. I’d like to expand it to provide better search by tags and richer reports. Perhaps one day we can do a mood tracking, personality tests, or somethign else based on your photos.

PodcastTracker.com (Web)

WHERE TO FIND IT: http://www.podcasttracker.com

WHAT IS IT: Podcast Tracker is a web service to track your podcast listening, view your basic stats and export your podcast listening history. It has several hundred users and thousands of podcasts and episodes.

STATUS / WHAT’S NEXT ONE DAY: Current version was built in Drupal 7 and remains active and maintained with daily users. I plan to do a full rebuild one day likely in Python with an API-first approach and integrated into existing podcast listening apps (or maybe one day build our own app for passive tracking).

QS Ledger (Python)

WHERE TO FIND IT: https://github.com/markwk/qs_ledger

WHAT IS IT: A Personal Data Aggregator and Dashboard for Self-Trackers and Quantified Self Enthusiasts. Currently integrates over 20 self-tracking services, including Strava, Todoist, RescueTime, Fitbit, Instapaper and many others. This python-based project contains dozens of Jupyter Notebooks and aims to be the go-to location for data collection and data visualization for self-trackers!

STATUS / WHAT’S NEXT ONE DAY: This is one of the most active open source project I hack on in my free time. It has over a hundred github stars now too. I plan to add or update some of the integrations and tightening the visualization aspects. I’d like to improve the beginner documentation and on-boarding. The next big steps aim at deeper analysis using statistical and. time series analysis as well as more machine learning and deep learning techniques.

Awesome Biomarkers

WHERE TO FIND IT: https://github.com/markwk/awesome-biomarkers

WHAT IS IT: Curated List of Biomarkers, Blood Tests, and Blood Tracking. Learn more about blood testing, biomarkers and tech and services to help quantify (and improve) your health! It currently includes several dozen common blood tests results.

STATUS / WHAT’S NEXT ONE DAY: My ultimate aim is to provide an open source and community database on and about biomarkers. That way we can build great technologies for individuals, companies and communities hoping to use biomarkers and health metrics to power their solutions. In the short-term I hope to provide reference ranges, more references to research papers and ideally a simple tool for checking latest labs. Long-term we need to explainable ML and AI that translate our blood tests and biomarkers into predictions and recommendations.

Drupal Modules

WHERE TO FIND IT: https://www.drupal.org/u/markwk

WHAT IS IT: Since learning to use Drupal in early 2010s, I’ve created and open sourced over 50 modules and themes on drupal.org. Most notable are Quizlet, Events Distribution, Flag Limiter, Toolbar Message, and Joyide of D7 among others.

STATUS / WHAT’S NEXT ONE DAY: While these modules are still used actively on hundreds of sites, I no longer actively develop them outside of client and paid requests.

Legacy Stuff I’ve Built

  • BioMarkerTracker - Intended as a followup to Awesome Biomarkers DB, this apps aimed to a data-driven tool to help people understand, assess and take positive actions to improve their health. Still might resurface this one day but for now dev has stopped.
  • Language-Corner.org - Interactive CMS for language learning and teaching. Active from 2010 to 2012 and served over a dozen teachers and several hundred students.

Manifest Journal: Journal that Tracks, Empowered by AI

Manifest App

Launch Page and Newsletter Signup Open Source Code in React Native
What is it?
  • Manifest is a voice powered journal that offers you analytics about yourself over time. We utilize sentiment analysis open source tools to bring to you a new zoomed out perspective.
  • We are a team that met at a hack-a-thon in Los Angeles! We are building this app to help address the noisy world we all live in. We beleive journaling is key to growth and peace of mind.
Customer Interviews and Validation:
  • “Things I totally believed whole heartedly have completely changed over time. Through journaling, I realized the impermanence of things. But also felt a sense of recognition of my growth.” — Robert, Avid Journaler
  • “I’ve been journaling for the last 5 years and it’s really changed my life…I don’t miss big things in my life. I refer back to my journal all the time.” - Knight, Avid Journaler and Chess Player
What Has Been Built?

During the weekend, we created:

  • a react native app that provides
  • voice-to-text input and then uses
  • Natural Language Processing (NLP) from IBM Watson and Google’s BERT to
  • extract sentiment and emotion and
  • calculate “Growth Mindset” Asssesment

Active Work is being done on UX Design, Customer Development and new completely revised journaling app focused on voice-centered interaction and AWS Amplify integration.

TodoistExport.com

WHERE TO FIND IT: https://todoist-export.herokuapp.com/

FORMERLY: http://www.todoistexport.com/

WHAT IS IT: Website to export and download your completed tasks history from Todoist.com. Built using Python and Flask and integrated with Todoist API.

STATUS / WHAT’S NEXT ONE DAY: Largely built as a way to learn improvement my python and flask skills, I hope to expland it one day to include more charts, graphs and analytics.

NOTE: An Open Source Version is also available here: https://github.com/markwk/todoist_export
