๐จ Starting the challenge!
So I officially started my 0 โ $4,000 MRR SaaS in 365 days challenge today.
DAY1:
The product is called FeatureNest. It's for collecting feedback and feature requests for your projects.
I want to make it stand out from the competition by implementing some unique features.
The coming soon page is ready. Let me know what you think about the design.
If you're interested, you can join the waiting list. ๐
almost all of my SaaS ideas come from expired domains
one of them made me ~$2k with a ~$270 investment
here's how ๐
I browse expired domains about once a week, used to do it daily when I was flipping domains for profit, but now I'm more focused on building.
I still think that a good domain from the start can boost your launch
back in February, OpenClaw was blowing up. I was scrolling through GoDaddy auctions and spotted ClawTeam dot com
so I thought: pre-built agent configs, people want OpenClaw but don't know how to set it up... sell them ready made packs - simple idea
so I asked my own OpenClaw agent to help me figure it out, turns out agent configs are just a few markdown files with instructions and skills.
30 minutes later I had 5 agent packs ready to sell
I spent another hour building a simple landing page, added Stripe, and had everything ready before I even owned the domain.
2 days later I won the auction for ~$270 and launched ClawTeam dot com
for marketing I submitted to a few OpenClaw directories, and also started showing up in some GitHub repos, which started bringing good traffic and sales.
one landing page, a few agent configs, a good domain
~$2k in revenue
with minimal marketing effort
maybe it was luck, maybe right place right time
now the OpenClaw hype is gone, traffic is low and no sales
but the takeaway is simple - you can make money from almost anything... just ship it!
Iโve worked on enough apps to know that search is usually one of those features that starts simple and gets complicated fast.
At first, a basic keyword search feels fine.
Then users start searching the way real people actually think:
โShow me the most powerful car you haveโ
โHigh performance Italian cars above 700hpโ
โA Honda or BMW with at least 200hp, rear-wheel drive, from 20K to 50Kโ
And suddenly your search logic turns into a mix of filters, conditions, parsing rules, aliases, and edge cases.
Thatโs why @typesense caught my attention.
Typesense is an open-source search engine built for modern app and site search, and their built-in Natural Language Search support in v29+ is especially interesting.
Instead of forcing users to search with exact keywords, Typesense can translate plain English queries into structured search filters and sorting logic automatically using your preferred LLM provider.
So instead of manually handling queries like:
โA Honda or BMW with at least 200hp, rear-wheel drive, from 20K to 50Kโ
Typesense can understand:
โข car brands
โข horsepower requirements
โข drivetrain preferences
โข price ranges
โข sorting intent
without needing to build complex parsing logic on the application side.
Itโs a much cleaner way to build intelligent search experiences.
Other things I like about it:
โข Typo tolerance out of the box
โข Fast search-as-you-type performance
โข Simple relevance tuning
โข Laravel Scout and Django integrations
โข Minimal setup for production-ready search
If youโre building search into a SaaS product, ecommerce app, docs site, or internal tool, itโs worth checking out.

If you're stuck in your career as .NET developer
You can't get a better job or promotion.
Read this ๐
๐๐๐ป๐ถ๐ผ๐ฟ:
You're learning fast, but the .NET ecosystem is enormous.
โ You don't know which topics actually matter for getting hired
โ Interview questions feel random and you can't tell what's important
โ You're guessing what to study next and often guessing wrong
๐ ๐ถ๐ฑ-๐น๐ฒ๐๐ฒ๐น
You ship features, but the senior label keeps slipping past you.
โ You can't pinpoint what separates you from the seniors on your team
โ DI lifetimes, caching, messaging - you use them but couldn't explain them in depth
โ You're not sure what options to select. What are the trade-offs, pros and cons?
๐ฆ๐ฒ๐ป๐ถ๐ผ๐ฟ
You're senior on paper, but blind spots show up at the worst moments.
โ Topics you skipped early on now surface in architecture reviews
โ Interviewers probe areas you've never had to formalize
โ You want a structured map of what 'senior' actually covers
Instead, you need a system:
๐ฆ๐๐ฒ๐ฝ ๐ญ โ ๐ ๐ฎ๐ฝ ๐๐ต๐ฒ ๐๐ฒ๐ฟ๐ฟ๐ถ๐๐ผ๐ฟ๐.
Get a clear list of every topic .NET interviewers actually test on:
- C#
- OOP
- Async code, threads and locking
- Optimizations
- ASP .NET Core
- EF Core
- Caching
- Messaging
- Auth and security
- Architecture.
๐ฆ๐๐ฒ๐ฝ ๐ฎ โ ๐ฃ๐ฟ๐ฒ๐๐๐๐ฟ๐ฒ-๐๐ฒ๐๐ ๐๐ผ๐๐ฟ ๐ธ๐ป๐ผ๐๐น๐ฒ๐ฑ๐ด๐ฒ.
Run yourself through the same questions hiring managers ask in real interviews. If you can answer them with confidence, you're ready. If you can't โ you just found the exact gap to close.
๐ฆ๐๐ฒ๐ฝ ๐ฏ โ ๐๐น๐ผ๐๐ฒ ๐๐ต๐ฒ ๐ด๐ฎ๐ฝ๐, ๐ผ๐ป๐ฒ ๐ฏ๐ ๐ผ๐ป๐ฒ.
Stop jumping between random blog posts and half-watched YouTube videos.
Study what matters, in the order it matters, the same way the seniors who got there did it.
That's how:
โณ Juniors stop guessing and start studying with intent.
โณ Mid-levels finally close the gap to senior.
โณ Seniors patch the blind spots before they show up in an architecture review.

Most developers optimize for addition, meaning new features, extended functionality, and growing systems.
Good code is easy to remove.
This is such a great tip! ๐งโ๐ป
