Backend-focused software developer specialized in Python, FastAPI, automation, real-time systems, and Bitcoin Core integrations.

I build practical, reliable, and maintainable software with a strong focus on APIs, reproducible environments, technical documentation, automated testing, Docker-based workflows, and operational stability.

My work includes open-source projects around Bitcoin Core observability, PSBT workflows, cold wallet systems, automation platforms, and internal administrative tools.

Open to opportunities in Python backend development, FastAPI, APIs, automation, system integration, developer tools, and Bitcoin infrastructure.

• Python backend development
• FastAPI and REST APIs
• System integration and workflow automation
• Real-time data processing
• Bitcoin Core RPC/ZMQ integrations
• Docker and reproducible development environments
• Automated testing, CI/CD, and technical documentation
• Operational dashboards and internal tools

I build practical solutions around Bitcoin Core using RPC, ZMQ, regtest environments, mempool monitoring, UTXO handling, PSBT workflows, watch-only wallet flows, offline signing, and cold wallet concepts.

Current focus:

• Real-time Bitcoin node observability
• Transaction and mempool monitoring
• PSBT construction and signing workflows
• Cold wallet and offline signing systems
• Dockerized environments for technical evaluation
• Backend services connected directly to Bitcoin Core

Bitcoin Core intelligence dashboard built with Python, FastAPI, React, TypeScript, Docker, RPC, ZMQ, Prometheus, pytest, and GitHub Actions.

Real-time observability layer for Bitcoin Core nodes, combining RPC snapshots, ZMQ streams, mempool monitoring, structured logs, transaction classification, metrics, and a reproducible technical validation workflow.

Bootable Bitcoin cold wallet focused on offline signing, PSBT workflows, BIP39/BIP32 derivation, QR/UR transfer, watch-only exports, and air-gapped operation.

Designed for secure cold storage, offline signing stations, and key recovery workflows.

Suite of Bitcoin Core applications covering RPC mempool snapshots, real-time ZMQ monitoring, and multi-wallet PSBT workflows.

Built with FastAPI, React, Docker Compose, pytest, mypy, GitHub Actions, and reproducible regtest environments.

Adaptive study and exam platform built with React, TypeScript, Vite, Node.js, Vitest, ESLint, and pdfjs-dist.

Includes question bank management, adaptive recommendations, analytics, anti-repetition filters, and PDF-based data ingestion.
