The Effective Developer - Work Smarter, Not Harder

The Effective Developer - Work Smarter, Not Harder

We’re agile, we work in cross-functional teams, and we use the latest dev-tooling. With all those methodologies and technologies we should be highly effective, right? Most of us still struggle with balancing coding speed & quality and working on the things that really makes a difference.

Effective developers don't just write clean and robust code. They also have a strong understanding of the problem that needs to be solved and they take time to learn and play. Learn how those developers build effective coding habits, use automations whenever needed, reserve time for deep work, and much more.

She’s learning programming on her own time while working her day job, and developing her own app as a learning tool/portfolio piece. She’s especially conscious of price and ease of use (in that order) since she’s paying for everything herself. Learning to program will put me on the path to a better career. MongoDB seems like the easiest data layer to learn on and it’s free! TINA The Statistician DATA SCIENTIST EXPERIENCE Current Role Relevant Experience SUMM Tina analyzes data from several databases, then builds can write scripts to query MongoDB but she learne working on shifting her mindset to a document mode with data from various sou LUCAS The Advocate FULL-STACK DEVELOPER EXPERIENCE Current Role BUYING POWER 1 Year Technology Roles 8 Years SUMMARY Lucas is a MongoDB superfan. He brought MongoDB into his company, follows Eliot on Twitter and attends MongoDB World annually. He’s very interested in the philosophy behind software tools, and prefers those that are open-source and responsive to customers of all sizes. I love building elegant software. I always try to keep business logic in the code instead of third- party tools so they're easy to change, even if it creates more work.

    Role Primary MongoDB Learning Tools MongoDB University Certificate in progress Documentation BUYING POWER Decider COMPANY TYPE Freelance (Individual) 2 Years Technology Roles 6 Months MongoDB Experience Beginner SUMMARY Jasmin is making a big career transition, from customer service to tech. She’s learning programming on her own time while working her day job, and developing her own app as a learning tool/portfolio piece. She’s especially conscious of price and ease of use (in that order) since she’s paying for everything herself. Learning to program will put me on the path to a better career. MongoDB seems like the easiest data layer to learn on and it’s free! WHAT I USE Atlas Beginner Compass Beginner Stitch Beginner WHAT I DO Juggle my day job with learning to code in my free time Install, develop, and troubleshoot the tech I choose Manage all aspects of my project PAIN POINTS Learning on my own without a good support network MongoDB University courses require prior programming and database knowledge Understanding what to do next after completing each MongoDB University course WHY I LIKE MONGODB Atlas, Compass, and MongoDB University are free Atlas is easy to set up and get started with on my own Plentiful third-party tutorials available GOALS Ultimately transition to a career as a Full-Stack Developer Troubleshoot my own IT issues at an advanced leve Build an app to manage call center schedules as a portfolio piece I MIGHT ALSO USE TINA The Statistician DATA SCIENTIST EXPERIENCE Current Role Primary MongoDB Learning Tools Documentation BUYING POWER Consulted COMPANY TYPE Corporate (50-1000 employees) 4 Years Relevant Experience 8 Years MongoDB Experience Beginner / Intermediate SUMMARY Tina analyzes data from several databases, then builds clean data sets when needed, usually in SQL. She can write scripts to query MongoDB but she learned how to work on relational databases, so she’s working on shifting her mindset to a document model. Visualizations are important to Tina as she works with data from various sources to provide insights. We would like to do machine learning. We're currently working on that, but we're learning, too. So the main thing for us is data integration and data visualization. WHAT I USE BI Connector Intermediate Charts Beginner MongoDB on GCP Beginner Compass Beginner WHAT I DO Use scripting to combine data from all sources into a single pipeline Identify opportunities for increased efficiency and improved operations Analyze the data using statistical methods Create visualizations using Charts, Excel, or Tableau Provide key performance indicator (KPI) data to key stakeholders PAIN POINTS Large and cross-collection queries are time- and resource- consuming Data is in multiple places and formats Gap in visualization tools that predict based on data trends WHY I LIKE MONGODB Compatible with Python, R, and other scripting languages Works well with Jupyter Notebook for sandbox-type exploration Easy to integrate different types of data from multiple sources GOALS Create a shared understanding of how the company is meeting its goals from a data-driven perspective Gain actionable insights from the data I MIGHT ALSO USE LUCAS The Advocate FULL-STACK DEVELOPER EXPERIENCE Current Role Primary MongoDB Learning Tools MongoDB University Certificate BUYING POWER Influencer COMPANY TYPE Small Business (1-50 employees) 1 Year Technology Roles 8 Years MongoDB Experience Advanced SUMMARY Lucas is a MongoDB superfan.
