Lead Software Architect · India & Singapore
8+ years at Apple & Carbyne building distributed systems that handle millions of requests daily. I help enterprises reduce cloud costs, modernise legacy architecture, and integrate GenAI — with results you can measure.
I don't just write code — I design systems that outlast the sprint and move the metrics that matter to the business.
Designing fault-tolerant distributed systems from the ground up — built for reliability, horizontal scale, and the kind of traffic that wakes engineers up at 3am.
1M+ daily requests deliveredTransforming expensive monoliths into lean microservice architectures. I've cut cloud bills by 70% without sacrificing a millisecond of reliability — it's usually the first thing I find.
Up to 70% OpEx reductionBuilding production-grade RAG pipelines and LLM integrations that actually work in the real world — with the observability, evaluation, and guardrails enterprises need.
40% data freshness improvementFrom public safety systems that handle 911 calls to Apple's geospatial infrastructure — the kind of work where failures aren't an option.
Leading high-precision geospatial backend systems that power Apple Maps at scale. Drove the migration from batch to streaming pipelines — a change that had a measurable impact on real-time data quality for millions of users. Currently pioneering GenAI integration for intelligent data enrichment. My engineering standards were adopted across multiple cross-functional teams.
Designed mission-critical distributed systems for emergency response (911). When the system goes down, people die — so we built for five-nines reliability with ultra-low latency under sustained load. Built multiple core projects from scratch that became the backbone of Carbyne's public safety platform.
Fast-track promoted for results. Executed the strategic decoupling of a large monolith into microservices — cutting operational infrastructure costs by 70% while improving deployment velocity and system resilience. This is the work that showed me how much money sits hidden in architecture debt.
Consulted for global clients across Fintech, Edtech, and enterprise domains — delivering high-performance backend systems. Won the company's "Above and Beyond" award for excellence in reactive architecture and data engineering. This is where I built my foundation across industries.
The tools I reach for to solve hard problems at scale.
Most GenAI engineers skip the fundamentals. I built this roadmap to bridge the gap: from neural network intuition to shipping production RAG systems. Synthesised from Karpathy, Goodfellow, and my own production experience.

"I worked with Ayush as a direct manager; he built from scratch multiple projects crucial for Carbyne in the public safety domain. Ayush is a talent! He shares technical knowledge across R&D and shows real dedication to success."
"Ayush approaches every task with dedication and precision. He not only taught me new programming concepts but also helped me develop a deeper understanding of software architecture and design."
"Ayush has demonstrated impressive growth over his tenure. He has proven capabilities to take ownership of modules at enterprise level. His technical expertise is impeccable, especially in Big Data and Scala."
"His energy, adaptability, and readiness to take ownership are truly impressive. On Carbyne, Ayush demonstrated innovative thinking and a strong sense of responsibility."
Whether you need a fractional CTO, a distributed systems architect, or a GenAI strategy partner — I'd love to hear about the problem you're trying to solve.
