About

I care most about accuracy in distributed systems, databases, and concurrency. Tiny details decide whether a system stays correct or quietly falls apart.

Currently, I am an intern at Clockwork Labs, where I am building SpacetimeDB, a distributed real-time database that combines the database, application server, and synchronization layers into one high-performance environment.

I have also worked on scheduling performance and security at Cal.com and on GPU attestation and deterministic evidence pipelines at Ashiba Research. I have the most respect for code with clear, unambiguous, and explicit invariants.

Right now, I am drawn to real-time infrastructure, distributed databases, backend performance, open source systems software, indexing, search, schema design, correctness, and technical writing that makes complex systems easier to understand.

Experience

Jun 2026 - Present

Software Engineer Intern, Clockwork Labs

  • Developing SpacetimeDB, a distributed real-time database combining storage, application logic, and synchronization.
  • Improving correctness, scalability, and low-latency access for open-source multiplayer and collaborative infrastructure.
  • Writing practical technical material that helps developers understand real-time and distributed systems.

May 2026 - Jun 2026

Research Engineer Intern, Ashiba Research

  • Built ARC, a deterministic verification system for GPU telemetry, attestation tokens, and deployment logs.
  • Engineered NVIDIA attestation checks with nonce-based freshness guarantees for GPU identity claims.
  • Designed a canonical evidence pipeline across nvidia-smi, NVML, DCGM, OTEL spans, CloudTrail, and NVIDIA EAT JWTs.

Jun 2025 - Oct 2025

Software Engineer Intern, Cal.com

  • Improved reliability, performance, and security across high-traffic booking flows.
  • Replaced O(n²) scheduling logic with faster sorting, early-exit scans, and two-pointer techniques.
  • Strengthened conflict detection, availability filtering, cross-locale correctness, and reviewed 200+ PRs.
