Focus20 Labs
Building practical AI solutions, agents, and workflow automation for real business problems.
A little about me
Curious about how things work.
My background is in software engineering and building technology. Over time, my interests have expanded into AI products, business workflows, financial systems, and entrepreneurship.
I'm interested in the gap between an idea that looks impressive in a demo and a system that genuinely works in the real world.
This site is where I document the products I build, the questions I'm exploring, and the lessons I learn along the way.
The work right now
AI products and trading research are separate lines of work. Both stay on the record: build the system, test it against reality, and write down what holds up.
Restro20
A restaurant POS for everyday operational workflows.
GrabSaaS
A public site for finding SaaS products, offers, and tools aimed at founders and small teams.
Own Research
Analytics and simulation tools.
Finance and Trading Systems
Building the trading systems and algorithmic market research for Treasure Capital.
Current interests
The notebook is where those interests stay connected: how I think, what I have read, and whose public work I am studying. None of it is finished.
Ask AI about me
How Karthick Aravindan can help you. Choose an assistant and it opens with that question, pointed at this site. The answer is the model's, not a message from me.
A conversation
I take on a small number of practical AI projects: implementation, workflow automation, and technical product problems. If that is the kind of work you have, write to me or find me on Instagram, LinkedIn, and X.
