I'm Jigyasu Dhingra, a software engineer specialised entirely in fintech - the automated trading systems, execution infrastructure and financial platforms that have to be right when money is moving.

Since late 2024 I have acted as the de-facto CTO and sole engineer for a trading SaaS company - building the entire technical foundation from scratch: fourteen production systems across execution engines, real-time infrastructure, full-stack product, and cloud automation. All of it live, handling real capital, maintained and evolved by one person who knows every line of it.

The through-line across all of it is delivery. Architecture decisions get made fast, hard problems get automated rather than worked around, and nothing ships late. When you are the only engineer on a live trading system, those are not nice-to-haves.

I work alone and deliberately. One engineer, accountable from architecture to deployment, means no handoffs, no diluted understanding, and a single person who knows exactly why every decision was made. For the kind of system where a race condition is a financial event, that focus is the point.

I don't name my clients - and I won't name you either. In this industry, discretion is part of the job.

Currently open to new freelance project builds and the right full-time engineering role - particularly at a firm where the trading infrastructure is the product.
