Experience
Research Engineer
04.2026 - present- Migrated research and intelligent-service workloads to Kubernetes; maintained GitLab CI/CD pipelines and Grafana monitoring.
- Fine-tuned language models for AI-powered legal-service applications, moving research prototypes toward operational deployment.
- Developed real-time AI chat-assistance functionality for a personality-assessment service.
- Designed and published an anonymous service-provision protocol using blockchain and decentralized storage.
- Worked across infrastructure, AI engineering, applied research, and product requirements rather than within a single technical layer.
Research Engineer, Assistant & Lecturer
08.2020 - present- Research and build distributed systems operating under adversarial conditions, combining protocol design, implementation, experimentation, and security analysis.
- Designed Federated Distributed Key Generation (FDKG), including its formal model and security proofs, and implemented experimental evaluation in Rust (FGCS, 2025).
- Built prototypes in Rust, Go, Python, TypeScript, Solidity, and Circom across distributed systems, blockchain, privacy, MPC, threshold cryptography, and zero-knowledge systems.
- Developed a quantitative framework for reasoning about trust, compromise, and collusion, and designed published protocols for privacy-sensitive applications.
- Taught Cryptography and Blockchain Technologies for 3+ years, supervised student research and engineering projects, and published 9 first-author papers.
Founder & Software Engineer
2019 - 2024- Built and operated Vape Tool, a consumer mobile product with 3M+ downloads and approximately 200k active users.
- Owned the complete technical lifecycle: architecture, Android application, backend services, data storage, deployment, monitoring, reliability, and ongoing product development.
- Made technical and product decisions independently, balancing delivery speed, maintainability, reliability, user needs, and business constraints.
- Architected and implemented backend systems for Tax Ledger, a cryptocurrency tax-accounting product integrating blockchain transaction data.
- Operated software and infrastructure used by real customers, with end-to-end accountability for outcomes rather than a single component.
Android Software Engineer
10.2014 - 01.2021- Delivered Android applications and features end-to-end for commercial projects.
- Worked directly with clients and loosely defined product requirements, translating them into shipped software integrated with backend systems and external services.
