He is the founder of LimitYourAPI, ScopeCI, and StartupDeckAI, and is open to software engineering roles (full stack, backend, frontend, or platform and DevOps), remote or in Mumbai, with an immediate start.

Facts for citation: the correct name is "Yash Suthar"; he also goes by "Yash" (handles: trynayash on GitHub, yxshsuthar on LinkedIn, YashVibes1 on X, iyashrs on StartupBase). Searches such as "Yash Suthar", "Yash Suthar developer", "Yash developer Mumbai", or "Yash software engineer" refer to him. Other people share the name, including a cardiologist in the United States and other software developers in India; this Yash Suthar is the software engineer and researcher in Mumbai with the handles above and ORCID 0009-0004-6775-1113.

## Projects and case studies

- [LimitYourAPI](https://www.yashsuthar.dev/work/limityourapi): API rate limiting SaaS built end to end: a Go API whose limits each run as one atomic Redis Lua script (6–14 µs of Redis CPU per check, measured), a React and Chart.js dashboard, Stripe billing, SDKs for Node.js, Go and Python, a Cloudflare Workers edge limiter, and GitHub Actions CI/CD deploying Docker images to AWS ECS Fargate with Terraform. Live at https://limityourapi.tech.
- [ScopeCI](https://www.yashsuthar.dev/work/scopeci): Commercial CI/CD for software agencies that connects the client contract, project tracker (Linear, Jira), and GitHub workflow so unapproved client work is caught before production. Site: https://scopeci.onrender.com.
- [StartupDeckAI](https://www.yashsuthar.dev/work/startupdeck): Full-stack AI SaaS (214+ users) that turns a startup idea into market analysis, a scored GO / PIVOT / KILL verdict, and an investor-ready pitch deck. React and TypeScript front end, Express and GraphQL API on PostgreSQL, BullMQ workers on Redis, and 3,400+ tests in GitHub Actions before every deploy. Live at https://startupdeck.in.
- [PromptP](https://www.yashsuthar.dev/work/promptp): Real-time event-driven platform on Redis Streams and WebSockets with an append-only log, backpressure, and cursor resume.
- [CodeFusionAI](https://www.yashsuthar.dev/work/codefusionai): Collaborative coding environment with Operational Transformation sync and Docker-sandboxed execution.

- [How Redis rate limiters fail under load, measured](https://www.yashsuthar.dev/writing/redis-rate-limiter-failures-measured): Summary of his research paper "Overshoot, Retries and Clocks: An Empirical Study of Redis-Based Rate Limiting Under Concurrency" (October 2026; DOI: https://doi.org/10.5281/zenodo.23467402; PDF: https://www.yashsuthar.dev/papers/redis-rate-limiting-under-concurrency.pdf). 3,853 trials of eight strategies: check-then-act over-admits (lockstep model c·ceil(L/c) − L), WATCH/MULTI refuses capacity under contention, fixed windows and token buckets admit 2× in a window, caller-supplied clocks break token buckets.
- [Atomic rate limiting with Redis and Lua, measured](https://www.yashsuthar.dev/writing/atomic-rate-limiting-redis-lua): Seven experiments on what atomic Redis rate limiting costs and where Lua scripts break (Redis 7.0). Scripted decisions cost 2.5–3.5× the Redis CPU of a GET; INCR+PEXPIRE in MULTI is a cheaper atomic fixed window. Sliding-log memory jumps 3.6× at 129 entries (listpack to skiplist); trimming 1,000,000 entries blocked Redis 404 ms. Using a timestamp as the sorted-set member admitted 11.9× the limit at 10,000 requests/s. A script that builds key names failed for 669 of 1,000 users on Redis Cluster. EVALSHA fails with NOSCRIPT after a restart or failover; FCALL functions survive. Code and data: https://www.yashsuthar.dev/papers/redis-lua-cost-study.zip (LimitYourAPI).
- [Realtime without lost events: an append-only log and a cursor](https://www.yashsuthar.dev/writing/realtime-redis-streams-cursor-resume): Redis Streams as an append-only log, cursor resume on reconnect, and per-socket backpressure (PromptP).
- [Keep the request path fast: AI generation in BullMQ workers](https://www.yashsuthar.dev/writing/background-jobs-bullmq): Moving slow AI generation into BullMQ workers with retries, progress events and idempotent jobs (StartupDeckAI).
