03 / The person behind the projectsBanking by profession.
Banking by profession.
Building by instinct.
I’m a banking technology professional, AI practitioner and technology creator based in South Bangalore. I enjoy taking an idea from the first question through design, architecture, implementation and a working demonstration.
My work spans banking products, AI experiments and SDLC automation. Outside work, the same curiosity leads me to ESP32 boards, Raspberry Pi, embedded displays, robotics and amateur radio. This is where I document and share those explorations.
