Shubhanshu Aarsay — Senior Software Engineer Build in stealth. Ship loud.
Senior Software Engineer & founder of Optimus Foundry. I design and build backend platforms, CI systems and applied-AI products — for teams that need them fast, solid and easy to run.
Also open to senior / staff engineering roles.
What I do
/servicesPlatforms & CI/CD
Build pipelines, developer platforms and the Go services behind them — tuned for throughput, like the 20k req/s internals I worked on at CircleCI.
Event-driven backends
Microservices, queues and multi-tenant APIs on AWS — RabbitMQ, Lambda, GraphQL, Postgres — designed to scale without surprises.
Applied AI
LLM agents and AI features wired into real products and workflows — built through Optimus Foundry, from prototype to production.
How I build
/non-negotiablesClean architecture
Clear boundaries and boring interfaces, so the system is easy to change next year.
Observable by default
Logs, metrics and traces ship with the first release, not after the first incident.
Accessible by default
Interfaces work with a keyboard and a screen reader from day one.
Documented
Decisions, runbooks and APIs written down, so the next engineer isn't guessing.
