Designing and leading multi-tenant backend platforms with clear system boundaries, practical API contracts, maintainable data models, and delivery standards that survive team growth.

Staff Software Engineer · SaaS Architecture & AI-Assisted Engineering
I help teams design and deliver multi-tenant SaaS backends, AI-assisted engineering workflows, and reliable enterprise platforms.
I work with teams that need clearer architecture, steadier backend delivery, and pragmatic AI-assisted engineering workflows.
Designing and leading multi-tenant backend platforms with clear system boundaries, practical API contracts, maintainable data models, and delivery standards that survive team growth.
Building developer tooling and workflow automation that help teams reason about requirements, implementation paths, review quality, and delivery risk without turning engineering judgment into a black box.
Helping teams stabilize architecture, improve code review habits, raise test quality, and recover delivery momentum when product complexity has started to outrun the system.
I'm Aniruddh Bhilvare, a Staff Software Engineer focused on SaaS architecture, backend and distributed systems, and Agentic AI. I help teams turn complex product requirements into maintainable systems, cleaner delivery practices, and software that can keep growing after the first release.
I started my career building mobile applications across Android and iOS at Ecosmob, Netrix, and YUJ Designs, including a SIP/VoIP client for enterprise customers and a connected-vehicle app for Citroën. Over the years, my focus shifted toward backend and distributed systems, where I've worked on multi-tenant SaaS platforms, cloud services, and the data models that support them.
At Particle41, I combine enterprise software delivery with AI-assisted engineering workflows, including developer tooling, delivery automation, and practical evaluation loops that help teams move faster without compromising engineering discipline. I've also led teams of up to 8 engineers and helped establish standards for system design, clean architecture, testing, and code review.
