Full-stack engineer · Python & real-time systems
Dhananjay Mishra
I build backend systems that run while you sleep — trading engines, market simulators, automation — and I design websites like this one, end to end.

System status
The stack
Deep on the backend,
sharp on the front.
-
Python
The core language. Trading engines, distributed pipelines, and the glue between every system I ship.
runtime -
Django
For products that need everything: DRF APIs, Channels for WebSockets, and battle-tested patterns.
framework -
FastAPI
For speed: async endpoints, typed contracts, and docs that write themselves.
framework · async -
AI & LLMs
Claude and OpenAI APIs put to work — chatbots that know your business, document Q&A, pipelines that read and write for you.
integration -
JavaScript
And everything the browser can do — canvas animation, scroll choreography, responsive design. This site is the demo.
frontend -
Payments
Razorpay and Stripe, wired end to end — checkout, webhooks, refunds, reconciliation. Your website can take money from day one.

Deployment
Docker, Nginx, SSL, and a VPS tuned to stay up. I don't hand over code — I hand over a running system.

Algorithmic Trading Engine
[ fintech · low-latency ]A multi-account engine on FIX 4.4 with dual-session architecture — fault-tolerant order retry, cancel-replace, and position reconciliation, with trend, entropy, and mean-reversion signals driving the decisions.
Python · FIX Protocol 4.4 · cTrader -
Trading Simulator
[ fintech · real-time ]A deterministic market sandbox: Brownian Bridge price paths that hit their targets every time, reproducible for audits, with live PnL streamed over WebSockets.
Django Channels · Redis · Celery · cTrader Open API -
Email Campaign Automation
[ automation ]A multi-tenant platform for bulk campaigns and follow-up sequencing — Celery fan-out for concurrent batches, SMTP pooling for throughput, IMAP threading for reply detection.
Django · Celery · Redis · IMAP -
AAA
[ telecom · access control ]Advanced Authentication, Authorization, and Accounting for carriers, service providers, and wireless operators — who gets on the network, what they're allowed to use, and what it costs, all tracked in one system.
Python · Django · DRF · MySQL · LDAP -
This Website
[ design · full-stack ]The page you're reading — designed and hand-coded from scratch: canvas particle system, scroll-driven animation, dual themes, no templates, no frameworks. I build sites like this for businesses too.

The short version
fits on one page.
I'm taking on freelance projects and new clients right now — a trading system, an automation backend, or a complete website like this one for your business. And when the scope needs more hands, I have a team I bring in — you still get one point of contact. Let's talk.
