Pranav Meraga / Engineering portfolio
I’m Pranav, an engineer working across machine learning, software systems, and robotics. From candidate search to robotic control, I build systems that connect research with practice.

Retrieval, reasoning, and real-world systems.
ROBOTICS / UC BERKELEY Watch demoHECTUR Head & eye control for UR7e
Hands-free robotic control using facial tracking, ROS 2, and MoveIt. I contributed the concept, early FaceMesh prototype, inverse-kinematics planning, and the live presentation.
A candidate search engine combining vector and lexical retrieval, reciprocal rank fusion, cross-encoder re-ranking, and an LLM judge to evaluate role-specific criteria.

Compact context for agentsA Salesforce code-intelligence pipeline built for a founding MLE role at a startup. It indexes Apex and metadata into SQLite, then exposes deterministic, compact queries for LLM agents.
Improvements to a supplied futures backtesting system: PnL exception handling, crossed-quote validation, multi-strategy visualization, custom indicators, and unit tests.
An LLM agent for ARC grid puzzles, with structured prompts, text and JSON grid parsing, and an evaluation harness over 20 included puzzles.
A MacroBase-inspired pipeline that scores transactions, compares percentile thresholds, and explains anomalies with overrepresented categorical attributes.
