Ayush Soni — My Engineering Journey

This document is a deep, end‑to‑end narrative of my work as a full‑stack engineer, covering how I think, design, build, scale, and ship products from 0 → 1 and 1 → N. It explains real problems, trade‑offs, system design decisions, technical depth, and impact, rather than listing surface‑level responsibilities.

I strongly believe in ownership, scalability, maintainability, and performance‑first engineering. Across startups and product companies, I’ve consistently built production‑grade systems, led initiatives independently, and acted as a force multiplier for teams.

Engineering Philosophy

Before diving into individual companies, it’s important to understand how I approach engineering:

• Ownership first: I take responsibility from the idea → architecture → implementation → monitoring → iteration
• Design before code: I reason about system boundaries, data flow, failure modes, and extensibility
• Performance as a feature: Core Web Vitals, streaming, concurrency, memory usage, and network efficiency matter
• Scalable abstractions: Reusable components, domain‑driven modules, and predictable APIs
• Pragmatic excellence: Avoid over‑engineering, but never ship fragile systems
• Readable, maintainable code: Clear naming, modularity, strong typing, clean Git history

Attentions AI — Senior Ownership, Distributed Systems & AI Infrastructure

Role: Software Development Engineer (Frontend‑Heavy Full Stack)

Location: Pune, India (Onsite)

Attentions AI is where I operated closest to a senior / lead engineer, building multiple enterprise‑grade AI products almost entirely from scratch.

High‑Level Responsibilities

• Designed and shipped multiple micro‑frontends used by enterprise clients
• Built real‑time systems using WebSockets, SSE, pub‑sub architectures
