Hi, I'm Ayush Saxena, a software engineer.
I build high‑scale, low‑latency systems. multi‑tenant AI platforms. distributed systems. products thousands rely on every day. AI that cuts costs, not corners.
I specialize in software architecture, distributed systems and generative AI, and I enjoy turning hard problems into simple, scalable systems. Right now I'm an SDE 2 and founding engineer at Meesho AI Services, building the core platform the vertical runs on.

Real-time insights and guided actions for 2,000+ concurrent support agents, all in one interface, which also brought agent costs down.
−35%average call handling timeNo-code agent builder
DAG-based orchestration on a config-driven CRM and data platform. 50+ product and business people launch agents themselves, with far less dependence on engineering, and new clients onboard much faster.
Config, experiments and rules engine
One platform for configuration, live A/B experiments and business-logic changes across 10+ services.

Region selection and cross-model fallbacks that cut mean latency by 200ms and let the platform recover from provider incidents 90% faster.
−75%LLM error rateLower voice bot cost per call
Reduced through a model experimentation platform and cross-model fallbacks, enabling faster evaluation and onboarding of new LLM, TTS and ASR models.

About
I'm a Software Development Engineer 2 at Meesho. I joined as an intern in 2024, helped launch India's first LLM-powered customer support voice bot at scale, and then became a founding engineer of Meesho AI Services.
I like problems where distributed systems and AI meet: routing across models and regions, keeping latency low on real-time voice, and building platforms that let other people ship agents without waiting on engineering.
