Why this, why now

I keep running the same loop:

• Building products with AI at the core
• Wrestling with TypeScript, Python, and Go
• Trying to make the products actually grow instead of just looking flashy

I keep thinking these attempts should not stay locked in my head.

So this blog is how I express it:

• Force myself to write down what I learn about AI, business, and indie products
• Share concrete cases instead of vague motivation
• Build a small corner for people who care about this stuff

I am not starting because I have figured it out—I am starting because I have not, and I want to document while I go.

• You build things (or want to): apps, tools, scripts, services
• You are curious whether AI is useful in the real world, not just in hype or papers
• You care about software and business together: pricing, funnels, retention—not just clean code
• You like peeking behind the curtain: failed launches, messy dashboards, real trade-offs

The vibe I want:

• Less “thought leader,” more fellow builder leaving you long voice notes
• Less polished essays, more honest breakdowns, experiments, and failures
• Normal to talk about what worked, what was wasted effort, and what we will change next

I hope it becomes a small, nerdy, high-signal community of people who ship, share, and help each other avoid obvious cliffs.

Topics

• AI and product: how I use LLMs in real products—prompts, architectures, failure cases, bright spots
• Indie dev and entrepreneurship: validating ideas, shipping fast, moving through uncertainty, small bets vs big bets
• Engineering notes: React/Next.js production patterns; Python/Go for backends, automation, and glue; deployment and monitoring

Cadence

• Target one post per week, depth-dependent
• Shorter field notes when I find something useful
• Longer stories when there is a full arc from idea -> launch -> results
• Prioritizing signal and sustainability over volume

• If I ever add a paid tier, it would focus on deep case studies, build logs, or small-group AMAs, and I will keep it straightforward.
