AI staff engineer that designs systems and guides coding agents
Lalit Kundu, Founder
Hey everyone 👋 we’re Lalit & Catherine, co-founders of Delty.
TL;DR
🚀 Delty is your AI Staff Engineer, trained on your team’s code, docs, and systems. With its deep systems understanding, it helps design and iterate upon enterprise-scale software systems.
Use Delty to:
- Design new features, services, or migrations with an expert AI teammate.
- Supercharge AI coding agents like Copilot with systems and team context.
- Onboard engineers fast—ask Delty how your systems works.
Ask: Is your software engineering team seeing the gap between AI prototypes and enterprise-scale software implementation? Email lalit@delty.ai or book a demo here.
🚩 The Problem
The most impactful engineering happens outside the codebase, in designing systems, technical strategy, and implementation planning.
But today’s AI tools skip all that. They write code without understanding your systems or engineering norms, leading to tech debt, incidents, and rework.
Staff engineers have expert systems knowledge, guide teams, and scale quality. AI tools can’t do that today. It looks good in demos, but breaks down in production.
🛠️ Our Solution
We’re a team of former Google staff engineers and AI experts building Delty—AI that works like an expert enterprise engineer, not just a code generator.
Delty develops a deep system-level understanding of your codebase, team practices, product, and engineering norms. You onboard your context once and Delty becomes a persistent, trusted teammate.
Use Delty to:
-
🧠 Design systems with a thinking partner
Get first-pass design docs, architecture feedback, and tradeoff discussions
-
⚙️ Supercharge your AI coding agents with system context
Make Copilot or Cursor aware of your systems, dependencies, and conventions -
🧑💻 Get 24/7 help from an experienced engineer
Ask deep technical questions and get clear, informed answers
Hear from our users: “Delty proposed an idea I hadn't even considered. It felt like pair-designing with a Staff Engineer who had been working at our company for years.”
👫 The Team
Lalit and Catherine built large-scale systems together at YouTube, handling billions in revenue. That’s where they first saw the gap: AI tools that could code, but couldn’t engineer.
Lalit launched Google Pay in India and rose to Staff Engineer at YouTube in just six years. He led a 45-person team building monetization systems driving $XXB+ ARR. A lifelong programmer, his journey began with competing in the ACM-ICPC World Finals during college.
Catherine started her career at YouTube as a SWE before joining Google’s APM program, where she worked on ChromeOS and internal GenAI infrastructure, including multimodal model evals and AI agents for enterprise use. She holds a BA in Computer Science from Dartmouth.
