Chinmai Siddhartha

I design trading systems and lead the teams that build them.

Right now I'm Tech Lead at Equicom Technologies in Bengaluru, building a crypto derivatives exchange with a team of 30+ engineers and QA.

Over six years I've worked on exchanges, DeFi trading systems and smart contracts. For the last three I've led teams and advised on architecture.

What I'm responsible for

Architecture

I set the system design with the founders and chief architect: how order management, matching, wallets and market data fit together as Go services built for millisecond-and-below latency.

Teams

I lead 20+ engineers across backend, frontend and mobile, plus 10+ QA. I own release cadence, code review standards and architecture alignment across teams.

Risk and margin

I lead the design of perpetual futures margining, risk checks and liquidation: the parts of an exchange where a wrong number costs traders real money.

How a leveraged position gets liquidated

Margin and liquidation are where an exchange's risk engine earns its keep, and a big part of what I work on. Open a position, then drag the mark price and watch what the risk engine sees.

Side
Try:

100,000.00

  • Entry 100,000.00
  • Liquidation 90,452.26
  • Bankruptcy 90,000.00
Position size
10,000 USDT (0.1 BTC)
Liquidation price
90,452.26
Distance to liquidation
−9.55%
Unrealized PnL
0.00 USDT
Margin balance
1,000.00 USDT
Margin ratio
5.00%

Margin ratio is 5.00%. This long is liquidated if the mark price falls to 90,452.26, a move of 9.55%.

Show the formulas
Position size
margin × leverage
Margin ratio
maintenance margin ÷ margin balance, where maintenance margin = rate × quantity × mark price
Liquidation price, long
entry × (1 − 1 ÷ leverage) ÷ (1 − maintenance rate)
Liquidation price, short
entry × (1 + 1 ÷ leverage) ÷ (1 + maintenance rate)
Bankruptcy price
where margin balance reaches zero: entry × (1 ∓ 1 ÷ leverage)

Isolated margin on a USDT-margined perpetual. Fees, funding and tiered maintenance rates are left out so the math stays readable. This is a teaching model, not any exchange's production logic.

Selected work

Most of what I've built ran inside companies, under NDA, or on products that have since closed. Here's what I can share.

2025 – now

Equicom Technologies

In development

Crypto derivatives exchange

A centralized crypto exchange with perpetual futures. I lead the engineering org and own the architecture with the founders and chief architect, across matching, risk, margin and liquidation, wallets and market data.

Details stay private until launch.

Personal project

Running on Binance

Multi-strategy perpetuals trading system

A trading system for Binance USD-M futures that I designed, built and run on AWS. Live books trade on real and demo Binance accounts, while a dozen paper books run different strategies on the same 544-coin market feed, so ideas are tested side by side before money moves.

Every order passes a shared risk layer first: per-trade risk, exposure and per-coin caps, a daily loss brake, a liquidation buffer, price and data-freshness checks, a safe mode and a kill switch. Each live book has a paper twin, and every trade the live book refuses is recorded with its reason, so the gap between paper results and real execution is measured, not guessed.

UnTrade (formerly Kings Charts), built at Zeltatech

Retired

Algorithmic trading platform

A platform that ran quantitative strategies on Bitcoin perpetual futures for retail investors. I worked on its on-chain asset management and how it scaled. Assets under management peaked close to $1 million before the product was retired.

2022 – 2023

Zeltatech

No longer operating

Gaming Arcade

A Polygon arcade where players wagered crypto on 1v1 matches and tournaments, with NFT passes for holders. I wrote the smart contracts, which passed a CertiK audit, and co-authored the scaling whitepaper.

Our scaling work raised transaction capacity by about 30% and cut gas costs by about 25%. The product didn't take off commercially and was wound down.
