AI/ML Engineer Intern @ Teclusion AI
Co-built Visentix, a multi-tenant privacy-intelligence SaaS, as one of two engineers — an end-to-end LLM pipeline (clause decomposition, classification across 8 privacy domains, deterministic scoring) on FastAPI + PostgreSQL/pgvector with a self-hosted Qwen3-8B served via Ollama, deployed across Azure, a RunPod GPU pod, and Cloudflare Workers. Kept the AI out of the arithmetic with 14 versioned deterministic formulas, SHA-256 reproducible reports, row-level security across 56 tables, and a 1,000+ test suite. Also shipped BluePearl (intelligent document processing, −90% review time) and Vantage (ARIMA/SARIMA pricing engine, +6–10% revenue).
AI Intern, Emerging Tech @ PricewaterhouseCoopers
Built a full-stack agentic financial-advisory platform (FastAPI, Next.js, Gemini, custom Knowledge Graph), median response under 2s. Co-authored a white paper on AI-enabled software development.
A credit-decisioning platform for applicants banks can't score — underwriting from verified bank-transaction evidence (Account Aggregator) instead of a bureau score. A 9-gate deterministic policy engine makes every call with zero AI in the decision path, an 11-feature cash-flow scorecard (ROC-AUC 0.787, KS 0.45) explains each contribution, and a hash-chained audit ledger keeps it all auditable.
A reproducible study benchmarking five model families — ARIMA, GARCH, Prophet, KNN, and feed-forward neural nets — for 30-day stock-price forecasting, weighing accuracy (RMSE, MAPE) against complexity. Every comparison is grounded in statistical validation: ADF stationarity tests, ACF/PACF analysis, Ljung-Box diagnostics, and GARCH volatility modelling for risk-aware forecasts.
A dynamic pricing engine that pairs ARIMA/SARIMA time-series forecasting with ML to predict demand and price elasticity for every SKU. It reacts to competitor moves within business-set margin and brand-price floors — driving a 6–10% lift in optimized revenue and cutting manual pricing effort by 50%.
A serverless crisis-comms PWA spanning three transport tiers (WebRTC over Wi-Fi, animated QR sync, printed posters), deployable by URL in under 30 seconds with zero backend. A gossip sync engine with Bloom-filter anti-entropy, Ed25519 signatures, and NaCl end-to-end encryption hits sub-200 ms LAN sync — all in a 180 KB gzipped bundle.
