Hi there 👋, I'm Yash

Backend Engineer | Workflow Orchestration | Distributed Systems | Python & Go

I build the parts of a system that have to be right, not just fast — workflow engines, async data layers, streaming pipelines, and the compilers and schedulers underneath them.

🌍 Open Source

Zigflow

zigflow/zigflow

Durable workflows in YAML, powered by Temporal

✅ #568 — Merged · fix(utils): honour io.Writer contract in LogWriter.Write

An intermittent short write that killed script execution. A blank chunk returned n=0 with a nil error, and io.MultiWriter correctly treated that as a short write. Root-caused from a production symptom, reproduced with a regression test, fixed in one line.

📜 Listed in zigflow's AUTHORS · more on the way — I'm upstreaming a set of engine fixes one at a time.

🧠 What I Work On

  • ⚙️ Workflow orchestration & durable execution — Temporal, compensation, state you can reason about a week later
  • 🧩 Compilers & DSLs — graph traversal, lowering, validation, normalisation; the interesting bits are all edge cases
  • ⚡ Async Python at the data layer — SQLAlchemy 2.0, connection lifecycle, migration discipline
  • 🕐 Scheduling correctness — recurrence rules, occurrence generation, timezone-aware scheduling
  • 🔐 Auth & access control — asymmetric JWT, centralised verification, RBAC that holds at the fifth service
  • 🎥 Real-time media — RTSP, HLS, WebRTC, and the bandwidth arithmetic behind choosing between them
  • 🔍 Observability of distributed work — tracing an execution back to the intent that produced it

💻 Tech Stack

Languages & Frameworks

Python Go FastAPI Django DRF

Orchestration & Data

Temporal PostgreSQL SQLAlchemy Redis GraphQL

Infrastructure

Docker Kubernetes AWS Linux Git

Media & Protocols

FFmpeg OpenCV WebRTC

🎯 Currently

  • 🔭 Deep in workflow orchestration — compilers, durable execution, making failures legible
  • 🐹 Learning Go properly, mostly by fixing things in a runtime written in it
  • 🌍 Contributing upstream instead of carrying patches locally
  • ✍️ Getting better at the non-code half — design ownership, root-cause analysis, and writing things down
