My Mission
Hi, I'm Danny.
SIERRA is my answer to common OSINT pain points. Professional analysis tools should be clear, affordable, and private by default.
My goal is simple:
To give those around me and my community tools that help them feel safer, more confident, and more in control of the truth.
And if I can scale that, bit by bit, it becomes a way to make the wider world just a little better for everyone.
Born from Real-World Need
A friend's complex case exposed gaps in existing tools. Many were costly or rigid, and few supported freeform thinking. SIERRA grew from that need, favoring notes first, then entities, tags, and relationships as insights emerge.
Two Years of Solo Development
For the past two years, I've poured my heart into SIERRA. Balancing a full-time job with nights and weekends of building hasn't been easy, but it's been deeply rewarding. Every feature carries the weight of research, testing, and the hope that it will help someone solve a case that matters. This isn't just code — it's my way of putting better tools in the hands of those seeking truth.
What Drives Me
These principles guide every decision I make in developing SIERRA.
Community-Driven
I listen to every user, every feedback, every suggestion. SIERRA evolves based on real-world needs from actual investigators.
Accessibility First
Professional tools shouldn't bankrupt individuals or small organizations. I keep SIERRA affordable and powerful.
Innovation & Privacy
I push technological boundaries while respecting user privacy. MCP features that supports offline, automation that stays local.
