Good agents
need context.

I’m Himanshu. I build agentic AI, memory layers, and the backend systems they run on.

Built around the
hard parts.

Local and voice agents, data dependencies, scraper failures, and the context a model relies on. Six projects I want you to spend time with.

OmniDev

An agent that works with what’s on your Mac.

A native macOS app that searches files and screenshots with citations, edits code, and runs tests. Its local knowledge engine is also available to other agents through MCP.

Inside the build

SwiftUI connects to a local FastAPI engine. Vision OCR makes screenshot text searchable, while Ollama embeddings and SQLite support file-grounded answers. The agent uses scoped tools, approval prompts, and restorable file snapshots. Ollama mode supports local inference; Gemini is an optional cloud provider.

BlastRadius

See what a schema change breaks before it merges.

Traces a changed column through DataHub lineage to downstream tables, dashboards, and ML assets, then records the assessment alongside the data.

Inside the build

Separate column and table traversals distinguish evidenced impact from an unproven dependency. A bridge to dashboard input fields follows the final hop that lineage traversal misses. CLI checks can block a merge, while separate MCP tools scan changes and write findings back to DataHub.

I care about what
happens after
the prompt.

The interesting work starts when an agent has to carry context across sessions, use a tool safely, or recover from a failed action.

I work across Python and TypeScript, APIs and data stores, MCP tools and user-facing products. I like making the state visible enough that someone else can inspect what happened.

Memory that can changeProvenance, revisions, forgetting, and retrieval.

Actions with boundariesScoped access, approval gates, and auditable decisions.

Backends that keep their promisesPersistent state, retry-safe writes, and observable workflows.
