Andrew Nuisud

I'm a CS student at Boston University (expected May 2028), currently a Software Engineering Intern at Arcfield working on messaging and authentication infrastructure for Navy submarine systems in C++.

Previously: software engineering at CVS Health / Aetna on the 2FA auth flow serving 36M+ members, founder and backend engineer at Pixeltools.cloud, and research assistant at UC Merced building simulation tooling for protein expression dynamics.

Always happy to chat — say hi!

experience

Software Engineering Intern — Arcfield Aug 2026 – Present
Contributing to Navy submarine systems, implementing messaging and authentication infrastructure using C++.
Innotech Software Engineering Intern — CVS Health / Aetna May 2026 – Aug 2026
Migrated the 2FA auth flow serving 36M+ Aetna members to AWS, cutting redirect latency by 100ms; prevented QA outages across 5 teams via Redis caching; built a Dockerized log aggregation pipeline reducing incident response time for 3 teams; improved homepage LCP by 200ms on health.aetna.com.
Founder, Backend Engineer — Pixeltools.cloud Jan 2025 – Jan 2026
Increased peak trade execution throughput 62% via a real-time valuation engine; sustained 40K+ weekly API requests at 99.9% uptime; built an operations console serving 100+ users with sub-200ms response times.
Research Assistant — University of California, Merced Jul 2025 – Sep 2025
Built a Flask app simulating protein expression dynamics with BioCRNpyler, validated across 1K+ configs; optimized the simulation pipeline via compiled CRN caching, cutting average latency 53x (2.9s to 0.02s).
