I build reliable backend systems, developer tooling, and distributed cloud infrastructure: SDKs, asynchronous pipelines, event-driven microservices, and client-server integrations across the web and mobile ecosystem.
My focus is system correctness & developer experience: debugging complex integration lifecycles, eliminating race conditions, building deterministic testing harnesses, and ensuring client SDKs talk flawlessly to backend services.
Bridging client-side developer experience (Expo / React Native, TypeScript, webhooks) with mission-critical backend execution: offline-first distributed synchronization, robust state machines, automated CI/CD security pipelines, and high-throughput API architectures.
- 3,000+ contributions in the past year across developer tooling, backend infrastructure, and cloud systems
- CASA Tier 2 & OWASP ASVS v4.0 security specification author (9.7 TAC Security ESOF score)
- Engineered high-stakes platforms: offline-first intercity transit systems, concurrent examination engines, and automated AI workflow pipelines
- Specialty: Distributed state machines, SDK & API integration debugging, asynchronous task queues (Celery/Redis), and Linux/cloud platforms (GCP, AWS, Hetzner)
- OpsSwipe - A phone pager for indie developers: a code fix can only merge after CI replays the exact production requests that failed. Expo app, Supabase backend, GitHub/Render/Railway/Google Cloud integrations, 114 backend tests. Built solo in under four days (demo).
- zerodom - Parses a live web page into a flat, addressable graph of what's clickable and fillable for AI agents, with every selector checked for uniqueness against the document.
- Infra-Guard - Autonomous observability agent on LangGraph and Groq: root-cause analysis on raw log streams, with a remediation report in under 5 seconds.
- OWASP OpenCRE - Contributed frontend E2E migration to Cypress for the OWASP OpenCRE security framework (PR #984).
Developer-facing infrastructure cannot afford black-box assumptions. When an SDK fails, a webhook drops, or a network link severs, the system must fail gracefully and tell the developer why. Building software that developers trust requires deterministic lifecycles, rigorous network tracing, idempotent operations, and zero tolerance for silent failures.
Available for full-time US-overlap engineering roles in Developer Experience, Support Engineering, and Full-Stack/Systems.
