Sumit Kulkarni
Building systems where markets meet machines.
02 — Manifesto
I design and build the machinery behind modern trading: real-time market data, risk engines and automation, and the products people actually touch. I like problems where a millisecond matters and the details are the whole point. Boring technology, exciting outcomes.
03 — What I build
Five things I keep coming back to.
02
Risk & trading engines
Real-time risk, order management, and the rules that keep accounts alive.
03
Automation
Bots and copiers that execute with discipline, twenty-three hours a day.
04
Products & brands
Dashboards, portals and websites that people enjoy using.
05
Experiments
Small tools, generative art, and things that don’t need a reason.

04 — Playground
Touch the signal.
A few thousand particles and one finger. Drag sideways, tap to burst, tilt your phone.
Drag · Tap · Tilt
05 — Principles
Four rules I don’t break.
Latency is a feature.
Speed isn’t polish. In markets it is correctness: a late answer is a wrong answer.
Boring tech, exciting outcomes.
Proven tools used well beat clever tools used badly. Novelty belongs in the product, not the plumbing.
Measure, then believe.
Every claim gets a dashboard, and every dashboard gets questioned.
Details are the product.
The last five percent is the part people remember.
