Professional niche, not consumer
Each product solves the pain of a specific trade. Engine tuner, HVAC tech, pump calibrator. Not a generic productivity app.
ABOUT THE FACTORY
I build tools for
professional niches.
Microforge is an indie microSaaS factory for professional niches. Solo, no investors, no corporate team. Focused on products that solve real pain for people who work with their hands.

With a BSc in Computer Science, I've worked in infrastructure, networks and security for over a decade. Microforge is my attempt to build the tools professionals deserve — without waiting for a VC to decide it's worth it.
I started with fuel blending because it's the calculation I got wrong most on paper when I got into turbo-ethanol engines. Lambda began as a personal tool — it became a product when other tuners started asking how I did it.
No investors, no corporate team, no runway pressure. My call. The roadmap follows real customer pain, not an exit timeline. Whoever pays, decides.

Education & certifications
Formal foundation, not a tutorial.
The factory's rigor — auditable math, infra that doesn't fall over, customer data kept in-region — comes from real education and certification. Not a weekend hobby.

WHAT GUIDES THE FACTORY
6 non-negotiable principles.
Auditable math
Formulas with cited sources (ANP, ASTM, ACCA, Pearson, Anderson). Public tests on GitHub. No black box — the pro checks before paying.
Mobile-first on the shop floor
Works offline on a dirty phone, no signal, bad light. Not an office dashboard — a field tool.
Indie, no investors, no runway pressure
My call. Roadmap driven by real customer pain, not a VC exit timeline. Whoever pays decides — not a term sheet.
Serious infra · compliance by design
Customer data stays in its own region. LGPD/GDPR-ready, local payments, zero data brokers, zero marketing pixels.
