Hackathons / Wins & Awards

WeaveHacks 2 • Multi-agent Learning Loop

Agent Playground

Building multi-agent learning systems is only half the job: teams need deterministic safety scoring and deep observability to understand how strategies evolve, converge, and fail over time.

Demonstrated measurable learning improvements: hierarchical learning success rate ~72% → ~88% (+16%), and quality score ~0.74 → ~0.89 (+20%). The system includes a judge-friendly end-to-end demo flow (~5–8 minutes) plus automated tests for hierarchical behavior and security scoring integration.

Devpost • Content Creator Connector

AI-Influencer-Marketing-Agent

Influencer partnership workflows are fragmented: discovering creators, interpreting profiles, and generating personalized outreach requires multiple steps across research, matching, multimodal analysis, and traceable reporting.

Delivered a structured and typed pipeline (Pydantic models + structured workflow outputs) that improves debuggability and iteration speed. Included reusable toolkits for multimodal analysis (Selenium stealth screenshot capture) and streaming/traceability patterns so the workflow stays inspectable across runs.

AWS Hackathon • Natural Selection for AI Tool Generation

Darwin

AI-generated tools are risky by default: you need a system that can safely explore candidates, scan for vulnerabilities, and consistently pick the best outputs instead of trusting a single generation run.

Built a security-first evolution loop with explicit fitness weights (Security 40%, Success 30%, Speed 20%, Quality 10%) and robust Bedrock enablement/fallback so the system can run reliably in different environments. Included generation tracking and leaderboard/specialization insights to show improvement across runs.

Open Contributions

Core contributions to open-source systems focused on optimization, protocols, and AI infrastructure.

Open Contribution • Self-evolving Optimization Framework

The Convergence

Teams tuning agent/API systems need runtime adaptation and repeatable optimization workflows, not one-off static prompts.

Built core SDK and runtime loops for an open-source Python framework combining evolutionary optimization and multi-armed bandit runtime selection. Added production-oriented selection/update flows and extensible adapters/storage support.

PythonThompson Sampling

Open Contribution • Symbolic A2A Protocol

Vector Native

Natural language AI-to-AI exchange can be ambiguous and token-heavy, making systems less predictable and more expensive.

Implemented a protocol-first parser/tokenizer system for symbolic A2A communication with strict, hybrid, and fallback parsing strategies plus token reduction measurement tooling.
