Lead end-to-end full‑stack development across TypeScript/React frontends and Node.js backends. Design and version APIs, scale backend infrastructure (Docker, Kubernetes, Prometheus, Grafana), collaborate with product and external partners, ensure high code quality and automated testing, and own feature lifecycle from prototype to production.

Build and own data-driven dashboards and backend services for DeFi risk analysis. Develop React frontends, GraphQL APIs, and cloud-native data pipelines. Collaborate with research and protocol teams, mentor junior engineers, drive architectural improvements to the Alert Portal, ensure code quality through testing and reviews, and identify product and technical enhancements.

Design and build core payment infrastructure end-to-end: high-performance transaction processing, ledgers, reconciliation, settlement, and on-call support. Own system architecture for distributed, event-driven systems ensuring strict consistency, idempotency, fault tolerance, security, and continuous delivery in a high-throughput financial environment.

Lead frontend architecture and own web (React Router, Vite) and mobile (Expo) platforms. Design and ship complex user-facing trading features, drive performance and scalability, execute cross-stack adjustments with TypeScript/Node.js backends, and integrate AI-augmented developer tooling. Provide technical leadership and translate product goals into robust technical plans.

Design and build an internal platform and developer tooling to enable reliable, self-service deployments. Own a TypeScript-based Pulumi codebase and Kubernetes runtimes, implement IaC and GitOps patterns, define SLIs/SLOs and monitoring, and participate in production operations, on-call rotations, and incident response to ensure platform reliability and security.

Design, build, and operate large-scale, fault-tolerant web crawlers and data pipelines that collect, clean, deduplicate, and normalize web-scale datasets (terabyte to petabyte). Navigate anti-bot defenses and dynamic JS sites, optimize crawl performance and cost, and collaborate with research teams to produce ML-ready datasets.

Design and analyze A/B tests, perform deep-dive analyses to identify product opportunities, build dashboards and predictive models, partner with product and engineering to implement solutions, and establish analytical best practices across the organization.

Lead design and build of high-performance trading infrastructure: optimize transaction landing, prevent MEV, implement proprietary routing and cross-chain solvers, deploy advanced trading features, and provide technical leadership to a small engineering team.

Join as a founding full-stack engineer to design and build scalable systems, implement AI/ML for fraud detection and candidate evaluation, own features end-to-end, and shape the technical roadmap at a rapidly scaling startup.

Design, scale, and operate multi-region, high-availability cloud infrastructure; lead incident response and on-call rotations; build automation and tooling in Python/Go; enforce risk, security, and operational standards; mentor teams and drive infrastructure architecture decisions.
