About Me
Hey, Im Jona — a backend & blockchain engineer who builds systems that are fast, reliable, and built for real world scale. I specialize in designing production grade microservices, payment workflows with a focus on performance, security, and long term maintainability.
Ive led core engineering at a product startup, shipping systems from 0→1, optimizing high throughput pipelines, and integrating payment gateways, payouts, PSP flows, and reconciliation workflows. My work is driven by clarity, correctness, and operational reliability — not just code that runs.
If you need:
• Fast, secure backend APIs FastAPI / Node / Go
• Payment gateway or UPI/Banking integration
• Blockchain smart contracts / tokens / DeFi models
• High performance data or pricing pipelines
Then Im the right person for the job.
Let’s build something that works under load, scales cleanly, and lasts.
