About
I build the systems that keep large language models running in production: the part that decides which machine answers a request, and the part that lets an AI agent finish a long job instead of starting over every time something breaks.
- Software engineer and AI engineer working on LLM systems, agents, and inference. AI and Data Science graduate, 2026.
- A distributed LLM serving control plane in Go, Python, vLLM, and Kubernetes. It routes streaming requests by tenant quota, replica load, and KV-cache state, with backpressure, circuit breakers, and OpenTelemetry tracing.
- A durable agent runtime for MCP and computer-use workflows, with event-sourced state, checkpoints, retries, and crash recovery, plus scoped credentials, permission checks, and human approvals before sensitive actions.
- Tool-use post-training and LLM evaluation with PyTorch, Transformers, PEFT, QLoRA, and TRL, including deterministic tool-use environments and synthetic trajectories.
- At CHN Technologies I work on Django and NestJS services, PostgreSQL schemas and indexing, and Docker CI/CD. Before that I built Blazor and .NET components and profiled SQL performance at Wise Work.
- I founded OneDot Communications. Open to full-time software engineer and AI engineer roles, remote or relocating.

Experience
CHN Technologies
Current EmployerBackend services and mobile screens. Most of the work is making systems that already run in production go faster and ship with fewer manual steps.
- Refactored Django and NestJS service boundaries and REST API flows across shared application workflows.
- Redesigned PostgreSQL schemas and composite indexes after reviewing query patterns and the workloads they affected.
- Automated Docker build and release workflows through CI/CD, replacing manual deployment steps.
- Built cross-platform mobile screens with Flutter and React Native.

OneDot Communications
Current EmployerMy own company. It builds AI solutions and digital products, and alongside that I maintain custom Android builds for Xiaomi phones.
- Founded OneDot Communications in 2024, based in Coimbatore, building AI solutions and digital products.
- Started a customized AOSP ROM line alongside the AI work, to get hands-on with Android below the app layer.
- Built Andromeda OS, a custom ROM, and ported it from the Xiaomi 14 Ultra (CN) to the Xiaomi 11T Pro (IN).
- Maintain several builds, each in a private and a public variant: Ninja OS, Groot OS, and Batman OS.
- Work covers kernel customization, interfacing with hardware through software, and testing for stability and security in daily use.

An AI agent doing a long job on a computer usually dies halfway and starts again from nothing. This runtime lets it carry on from where it stopped.
- Event-sourced application state with checkpoints, retries, and crash recovery, so a task can resume instead of starting over.
- Scoped credentials, permission checks, and human approvals before sensitive tool actions.
- Isolated, idempotent execution, so a retried action does not repeat side effects.

- Go
- Model Context Protocol (MCP)

- Event Sourcing
- Distributed Systems
When thousands of people ask an AI model something at the same moment, something has to choose which machine answers each request. This is that chooser.
- Routes by tenant quota, replica load, and KV-cache state, with Redis and PostgreSQL for coordination and persistence.
- Bounded queues, backpressure, and circuit breakers for overload; canary rollouts for releases.
- Latency, cache behavior, and failover traced through OpenTelemetry.
