Shivansh Tiwari

Software engineer and co-founder — AI systems, interfaces, and the structure underneath them. Interested in harness engineering and research with real-world models.

Portrait of Shivansh Tiwari

Crux — Co-founder  qunt.in

Founding and building Crux — an AI product, and the company around it. Took it from idea to a working surface: the landing and brand system, browser-extension demos, auth and onboarding flows, internal demo tooling, and the systems underneath. The day-to-day spans product decisions, interface design, and engineering — owning whatever the current bottleneck is.

Independent work — agent systems & harness research

A continuing line of self-directed builds in AI orchestration, retrieval, and sandboxed execution — the projects below. Current focus: harness architecture — studying how the loop, tools, context, and control surfaces around a model shape what it can do, reading the research and building against it. Several projects are private; ask and I’ll walk through them.

Orchestrator private

Hierarchical agent system — intent routing, planning, sandboxed execution — that researches, writes code, and produces finished documents.

python · 4 llm providers · 18 tools

Agentic Report Generator private

One prompt in, a citation-backed PDF out: a multi-agent pipeline that plans, searches, scrapes, writes, and renders end to end.

python · langchain · fastapi · quarto

SagaForge private

Small-model pipeline for a 300-chapter novel: canon store, power graph, foreshadowing ledger, rolling-wave planning.

python · sqlite · local models

SWE agent private

Minimal planner–programmer loop that reads a repo, patches, runs tests, and opens the pull request.

node · gemini · github api

PlanAct github

Readable ReAct-style reference agent: plan, execute in a sandbox, observe, recover from failure.

python · e2b · multi-provider llms

CodeRAG Navigator github

Chat with a codebase in natural language: hybrid semantic + keyword retrieval, answers grounded in cited source.
