Built an AI-powered crypto signal engine delivering real-time, explainable trading intelligence across 10 languages.

• Designed a polygonal signal engine fusing technical indicators, on-chain data, order-book microstructure, and multilingual news feeds from 50+ sources with sub-second latency.
• Engineered a Python backend (FastAPI/Django) with Redis caching and Celery task queues, reducing p95 latency by 45% and database load by 60%.
• Implemented sequential route evaluation for up to 9-hop trading paths, enabling capital-efficient execution.
• Developed regime-aware scoring models with backtesting infrastructure for model validation.
• Deployed a privacy-first, non-custodial architecture with risk overlays, discipline guardrails, and zero external funding.
• Built CI/CD pipelines with pytest, Docker, and zero-downtime deployments; scaled to 1,000+ daily active signals.

Led backend infrastructure and deployment automation for a fast-growing platform.

• Delivered MVP using Django REST Framework and FastAPI; improved API response times by 45% through query optimization and Redis caching.
• Hardened production systems (Linux, Nginx, SSL/TLS, 2FA), reducing security risks and ensuring compliance.
• Established Docker-based CI/CD pipelines enabling daily zero-downtime releases.
• Mentored cross-functional teams on best practices, cutting technical debt by 30% and accelerating feature delivery by 2×.

Built a high-performance platform for Persian-speaking first-grade students.

• Architected a Django-based system serving 2,500+ students, handling 27K+ monthly requests on minimal VPS resources.
• Reduced SQLite load by 60% via Redis caching and query optimization; achieved 99% uptime.
• Integrated book-scanning with audio playback for interactive learning.
• Configured full DevOps stack: Docker, Nginx, Cloudflare CDN, TLS/SSL, automated backups.
• Served 9GB/month traffic with 7GB cached via Cloudflare.

Launched censorship-resistant VPN for adversarial environments.

• Designed a socket-based networking layer bypassing deep packet inspection using DNS tunneling and protocol obfuscation.
• Scaled to 50+ nodes with automated Linux deployment; achieved 99.9% uptime under active attacks.
• Implemented zero-log policy, end-to-end encryption, and real-time attack detection.
• Served 1,000+ users in restrictive regions.
