Harbor

Next.js, React, TypeScript, PostgreSQL, Prisma, Plaid, LLMs

• Personal finance app that syncs bank transactions via Plaid and imports CSVs, statement PDFs, and Google Sheets through a column-mapping wizard.
• Categorizes spending with user rules or an optional LLM (OpenRouter, Gemini, or local Ollama), which also extracts transactions from uploaded statements.
• Envelope budgeting with rollover, safe-to-spend and overspending alerts, plus subscriptions, net worth, debt payoff, goals, and an income-to-spending Sankey view.

Prism

FastAPI, Next.js, TypeScript, PostgreSQL, Ollama, LaTeX

• Full-stack job search workspace: discover roles across JSearch, Greenhouse, and Lever, then track applications on a drag-and-drop Kanban board with funnel analytics.
• Local-LLM resume tailoring, ATS scoring, job match scores, and outreach email generation, with LaTeX-rendered PDF resumes.
• JWT auth with per-user data isolation, Gmail sync for inbox status updates, a LinkedIn browser extension for saving jobs, and Docker + Postgres deployment.

Quorum

Next.js, TypeScript, FastAPI, SQLite, Ollama, Docker

• Personal control plane where a multi-agent AI council (Skeptic, Optimizer, Privacy) deliberates over candidate plans and the user casts the deciding vote.
• Unifies 8 connectors (Gmail, Calendar, Notion, Obsidian, Slack, Linear, GitHub, Todoist) into a SQLite-backed knowledge graph used for graph-augmented retrieval.
• Every write is approval-gated, provenance-tracked, audited, and reversible where possible; runs fully local on Ollama with schema-constrained output.

Lattice

React, TypeScript, Supabase, Edge Functions, OpenAI, Ollama

• Research collaboration network connecting students, labs, and departments through RA and collaboration posts, researcher search, applications, messaging, and a ranked grant feed.
• AI lab assistant and explainable match scoring (methods, fields, LLM re-rank, timeline fit) on Supabase Edge Functions, plus cold-email drafting and paper chat.
• Production-minded backend with row-level security, notification and email outbox jobs, department roles, interview scheduling, and CI covering typecheck, lint, and RLS tests.

Moltbot

Python, FastAPI, Kalshi API, Ollama, SQLite

• Always-on agent running a deterministic trading engine for Kalshi prediction markets, with OpenClaw as its messaging gateway.
• Tiered market-monitoring loops and local-LLM news scoring, with hard risk gates: exposure and daily-loss budgets, a kill switch, and explicit live-trading acknowledgement.
• Paper (shadow) mode with fill simulation and fee-accurate PnL, a snapshot-replay backtester, and a FastAPI operator console for positions, orders, decisions, and alerts.

Fulcrum

React Native, Expo, TypeScript, SQLite, Vitest

• Local-first iOS/Android app combining a training log and nutrition diary to surface insights that need both, like strength on a cut or the energy cost of training.
• Framework-free TypeScript domain core with SQLite as the source of truth, versioned migrations, and a USDA food-ingestion pipeline producing an FTS5 search database.
• Kalman-filter energy model that turns intake and weigh-ins into trend weight, adaptive expenditure with uncertainty, and guarded calorie and macro targets.

content-gen

Python, Ollama, SQLite, FFmpeg, YouTube Data API

• Local autonomous agent that turns trending topics into YouTube Shorts, discovering and deduplicating stories from RSS and Hacker News and researching sources.
• Local-LLM pipeline with JSON-schema outputs and repair prompts for ranking, script writing, fact-check revisions, scene planning, and quality gates.
• Built to run unattended: resumable SQLite-backed jobs, retry with backoff, disk guards, rotating logs, and failure notifications.

Agentic DGG Conversion

Python, Pydantic, ChromaDB, LLM agents

• Proof-of-concept multi-agent pipeline converting Dynamical Graph Grammar models between research math (LaTeX + graph diagrams) and the FoxFlow simulation DSL.
• Agents are grounded with per-agent RAG over research papers; a typed Pydantic model is the hub representation, with deterministic FoxFlow emission and validation.

Concept-Guided RAG

Python, sentence-transformers, BM25, BEIR

• Reproducible retrieval-evaluation framework testing whether LLM-extracted concepts add ranking signal beyond content similarity.
• Compares 10 retrieval methods (BM25, dense, HyDE, fused, oracle and shuffled-concept controls) across lexical-overlap subsets with bootstrap CIs and significance testing.

React, TypeScript, FastAPI, SpoonOS, ElevenLabs

• Hackathon-built AI career discovery platform where six specialized agents analyze a user's onboarding in parallel to match them to careers.
• Voice onboarding and gamified roadmaps with XP, levels, streaks, and phase unlocking across learning, project, networking, and simulator tracks.

Java, Servlets, PostgreSQL, Redis, Kubernetes

• Full-stack movie e-commerce site with title and genre browsing, full-text search with autocomplete, and a session-backed cart and checkout.
• Hardened with BCrypt, reCAPTCHA, CSRF tokens, and rate limiting; scaled with connection pooling, a primary/replica read-write split, Redis caching, and Kubernetes manifests.

Python, SSA IR, Graphviz

• Compiler for the Tiny language with a hand-written lexer, recursive-descent parser, and SSA IR generation with phi nodes over basic blocks.
• Optimization passes for constant folding, copy propagation, and common-subexpression elimination, with Graphviz control-flow graph output.

Python, NLTK, Inverted Index, TF-IDF

• Disk-backed inverted-index search engine with stemming, weighting for title and heading terms, partial-index merging, and byte-offset term lookup.
• Ranks results with TF-IDF cosine similarity plus positional and proximity boosts, with term and query caching for sub-second retrieval.

Python, REST APIs, LLMs

• Automated equities trading system using LLMs for market analysis and the Charles Schwab API for execution.
• Implemented risk management with stop-loss mechanisms and real-time market monitoring.
