Building d8a.academy in public · 20/30 Hard lesson on gamification: a leaderboard motivates the top 10% and quietly demotivates everyone else. The person in the middle looks up, feels behind, and leaves. I had to design for them, not the people already winning. It cuts both ways. #buildinpublic

Building d8a.academy in public · 19/30 Adding a community changed the product more than any feature. Motivation is fragile in private, durable in public. Accountability isn't a soft extra, it's a core feature. #buildinpublic #data #productivity #motivation #community

Building d8a.academy in public · 18/30 Onboarding is key. The first minutes decide whether someone ever comes back. I spent more time on that first session than on entire features. Highest-return work I did. You don't get a second chance at the first impression. #data #buildinpublic #onboarding

Building d8a.academy in public · 17/30 The data path nobody talks about enough: Business Analyst. Barely any code, huge influence on what gets built, and your past career transfers straight in. From finance, healthcare or ops? You're already half a BA. #business #Analyst #data #businessanalysis

Building d8a.academy in public · 16/30 I built a public portfolio for a fictional analyst just to show what "good" looks like. Showing the destination motivates people far more than describing the path. Most people aren't lazy, they just can't picture the finish line #buildinpublic #data #portfolio

Building d8a.academy in public · 15/30 Most of a business analyst's value is invisible. It lives in conversations, careful emails, and requirements that quietly keep a project on track. So if the work is invisible, how do you prove you can do it? #data #business #buildinpublic #businessanalyst

#data #learn #student #job #portfolio

Building d8a.academy in public · 14/30 SEO is the most boring, highest-leverage work I've done. One article that ranks brings people in quietly, every day, while I sleep. Nothing goes viral. But compounding beats viral over any timeline that matters. #SEO #Buildinpublic #data #saas

Building d8a.academy in public · 13/30 I wrote a post that didn't mention my product until the very end, as one of three resources. It beat every aggressive version I'd tried. People smell when you're taking vs giving. Lead with the give and the rest takes care of itself. #Data #buildinpublic

Building d8a.academy in public · 12/30 Marketing lesson that changed everything: nobody clicks something that smells like an ad. The posts that worked were honest stories with the product buried among other useful resources. Give first. Be the least salesy person in the room. #data #buildinpublic

Building d8a.academy in public · 11/30 Pricing humbled me. I treated it like math when it's really psychology. The number mattered far less than how clearly I explained what you get. When the offer was confusing, no price worked. When it was clear, the price stopped mattering. #data #buildinpublic

Building d8a.academy in public · 10/30 A free signup that reaches a real, working dashboard beats a locked tour every time. People won't pay for value they haven't felt yet. Let them touch the thing first. The paywall comes after the "oh, this is useful", never before. #buildinpublic #data

Building d8a.academy in public · 9/30 I kept adding things. Users were asking me to remove friction. It took me too long to learn that "what can I delete" is a better product question than "what can I add". Most of my best work this year was subtraction. #buildinpublic #data #product #saas

Building d8a.academy in public · 8/30 Every feature I was sure people would love got ignored. Every feature I almost cut got used daily. I've stopped trusting my own taste about what's valuable. Now I ship it, watch what gets touched, and let usage decide. #Buildinpublic #Data #Job #Shipit

Building d8a.academy in public · 7/30 Uncomfortable truth about data jobs: the work is mostly SQL, dashboards, and explaining things to people who don't speak data. Not deep learning, not fancy models. Build for that reality, not the Twitter fantasy. That's what gets you paid. #data #buildinpublic

Building d8a.academy in public · 6/30 I shipped the first version as soon as possible. Also the best call I made: real users showed me in a week what I'd have guessed wrong for six months. Shipping early isn't reckless, it's the fastest way to stop being wrong. #buildinpublic #data #job #portfolio

Building d8a.academy in public · 5/30 So many juniors are stuck in the same loop: they think they need to "finish learning" before they're allowed to build, so they never start. But you don't learn data then build. You learn data by building. #data #portfolio #student #learning

Building d8a.academy in public · 4/30 Making content is the easy part. The hard part is getting someone to pick a small, messy, real project where you actually get stuck, and getting stuck is the whole point. Most of the work is convincing people that's worth it. #data #portfolio #buildinpublic

Building d8a.academy in public · 3/30 Biggest lesson so far: a certificate says you watched a course, a portfolio says you can do the work. Recruiters tell the difference in 30 seconds. The whole product is just a machine to move people from the first to the second. #buildinpublic #data #portfolio

The gap shows up fast once you stop consuming and start shipping small proofs. A single worked dataset beats another certificate every time.

Building d8a.academy in public · 2/30 People grind through course after course, then apply and hear nothing back. Not even rejections, just silence. The reason is brutal but simple: nobody hires you for what you watched. They hire you for what you can show. #buildinpublic #data #job #learning

Building d8a.academy in public · 1/30 Online courses are lying to people. You finish 10 of them with certificates, and still can't get hired. So I'm building the opposite: a place where you learn data by shipping projects. I'll share the day by day here. Follow along #buildinpublic #data

Last time I tried to do the 30 days post challenge and failed haha. I'm trying a new one 🫡

Day 5/30 Today I asked for as much feedback as possible on the app. And I think we are gonna pivot a bit, doing a better version of what we do, but everything well integrated. The app right now is just an addition of too much feature. I will let you know the next few days #data #buildinpublic

Day 3/30 Today I'm deep in the 14+ project roadmap. SQL, Python, Power BI, BigQuery, R, ETL… Each project mirrors real analyst work. Each one builds your portfolio. The hardest part isn't building the content, it's making sure every project actually prepares you for the job. #buildinpublic #data
