Engineering the infrastructurefintech companies bet on.
OpenFlare builds cloud-native trading platforms, real-time data infrastructure, and MVPs for fintech, healthcare, and e-commerce teams — with Go, React/Next.js, FastAPI/Flask, Kubernetes, and production-grade observability.
How we work
Build. Scale. Operate.
Build
Production-grade backend and frontend systems in Go, Python (FastAPI/Flask), and React/Next.js, engineered for correctness first, not just a demo that works once.
Scale
Deployed on Kubernetes with real-time infrastructure — Centrifugo, WebSockets, message buses — built to hold up under market-hours load, not just a local dev server.
Operate
New Relic and Sentry wired in from day one, so regressions and incidents get caught before your customers file a support ticket.
What we do
Full-stack fintech engineering
Cloud-Native Deployment & DevOps
Kubernetes, Docker, and CI/CD pipelines built for zero-downtime fintech releases.
Backend Engineering
Go, FastAPI, and Flask services designed for correctness under real trading-hours load.
Real-time Infrastructure
Centrifugo and WebSocket architectures for live market data, order updates, and notifications.
Fintech Platform Engineering
Broker integrations, options analytics, and trading terminals grounded in real production experience.
Security Audit & Assessment
OWASP Top 10 review, authentication hardening, and compliance-ready security posture.
MVP Development
Validated, production-ready MVPs for healthcare, e-commerce, and fintech teams in weeks.
Why fintech companies choose us
Engineering big fintech companies can trust
Built for market hours
Real-time infrastructure engineered to hold up at the 9:15 AM open, not just in a demo.
Observability from day one
New Relic and Sentry wired into every deploy from the start, not bolted on after the first incident.
Broker-grade integration experience
34 live broker integrations shipped in production across our open-source fintech platforms.
Cloud-native by default
Kubernetes, Docker, and CI/CD pipelines — not a manual deploy script someone runs from their laptop.
Security-first engineering
OWASP-aligned audits and hardened auth (Argon2, encrypted secrets) baked into every platform we ship.
We dogfood our own stack
The Fullstack Trading Terminal we're building in-house runs on the exact stack we bring to client work.
Real engineering, not slideware
We build in the open
Three production fintech products, fully open source. This is the same engineering bar we bring to client work.
OpenAlgo
Self-hosted algo trading platform connecting 34 broker integrations behind one unified API.
OpenBull
FastAPI options-trading platform with a Black-76 Greeks engine and sandbox settlement.
OpenAlgo Charts
From-scratch canvas charting engine — zero runtime dependencies, published to npm.
Trading Terminal
Our flagship product: Go, Kubernetes, Centrifugo, and React/Next.js tied together end to end.
