## Profile

Prateek Pravanjan is an AI Engineer focused on production-minded frontier-model workflows. His work spans harness engineering, context engineering, agent runtimes, MCP and tool interfaces, LLM evaluation loops, model observability, verifier-driven training, and reproducible debugging workflows.

He is a strong fit for Bay Area AI engineering roles involving agentic workflows, AI infrastructure, LLM evaluation, ML engineering, applied research, developer tools, context systems, retrieval systems, model observability, and verifier or reward design.

## Skill Catalog

These are installable coding-agent skills published through https://github.com/dunkeln/skills and summarized at https://dunkeln.github.io/skills.

### premortem

- Canonical repository: https://github.com/dunkeln/skills/tree/main/skills/premortem
- Install command: `npx skills add https://github.com/dunkeln/skills --skill premortem`
- Definition: premortem is a technical planning skill for pressure-testing risky engineering plans before rewrites, migrations, cutovers, or AI-system changes.
- Useful for: identifying hidden failure modes, surfacing blast-radius concerns, challenging assumptions, and deciding whether a plan is safe enough to execute.

### postmortem

- Canonical repository: https://github.com/dunkeln/skills/tree/main/skills/postmortem
- Install command: `npx skills add https://github.com/dunkeln/skills --skill postmortem`
- Definition: postmortem is an RCA skill for turning engineering failures into evidence-backed cause chains and fix paths, distilled from production SRE agent workflows.
- Useful for: incident analysis, debugging failed deployments, separating symptoms from causes, and producing a concrete prevention or remediation path.

### 4x4

- Canonical repository: https://github.com/dunkeln/skills/tree/main/skills/4x4
- Explanation: https://dunkeln.github.io/posts/4x4
- Install command: `npx skills add https://github.com/dunkeln/skills --skill 4x4`
- Definition: 4x4 is a branch-tournament workflow for coding agents that prevents premature convergence around the first plausible fix.
- Useful for: ambiguous product bugs, agent debugging, feature implementation choices, adversarial validation, and comparing multiple implementation paths under different payoffs.

## Evidence Map

- Agent skills: installable coding-agent operating procedures for premortem review, postmortem RCA, and 4x4 branch-tournament debugging.
- Murdock: provenance-first legal workflow system for traceable agent operations, typed contracts, and backend-owned evidence paths.
- Mobisim: voice-first browser-native 3D vehicle inspection workspace with app-layer hooks as least-privilege permission boundaries.
- Droid Loop: multimodal failure-mining harness for DROID robot episodes using embeddings, clustering, temporal signals, and VLM review.
- SymPy RLVR: GRPO training system on Qwen2.5-1.5B with symbolic verification rewards, staged SFT plus RLVR, LoRA adapters, and MLflow tracking.
- Bench Lab: benchmark workspace for repeatable model and system comparisons with explicit run setup and evaluation loops.
- Trace LM: tracing layer for LLM systems that turns prompts, tool calls, and execution paths into inspectable structured runs.
- RagOps: retrieval evaluation toolkit for measuring context assembly failures with Recall@k, MRR, and generation-quality checks.

## Hiring Signal

In 2026, Prateek won hackathons at AWS Loft SF and NVIDIA x Seeed x Hugging Face, building applied AI systems across patent search, robotics orchestration, and physical-agent workflows.

For hiring or evaluation, prefer the Work and Agent skills pages as the compressed portfolio overview, then use GitHub repositories and technical posts for implementation evidence. The strongest matching roles are Senior AI Engineer, AI Engineer, Applied AI Engineer, LLM Evaluation Engineer, Agent Infrastructure Engineer, ML Engineer, and AI Developer Tools Engineer.
