Full-Stack Engineer Building PWAs, AI Automations & Secure Systems.
> ▌
I build installable PWAs that load instantly, automate workflows with N8N, and ship fraud-detection systems for fintechs that need to harden compliance.
What that actually looks like
Selected work
AML & Fraud Detection Toolkit
Live · GumroadA 6-rule BFIU-calibrated transaction monitoring engine plus a LightGBM ML layer for bKash/Nagad-style MFS data. Includes a calibration doc explaining why global AML tools misfire on South Asian mobile-money patterns.
Triageist — ER Triage Prediction
Kaggle Hackathon 2026Random Forest model predicting Emergency Severity Index (1–5) from patient vitals, built for a $10K-prize Kaggle hackathon. Documents its own limitations openly — synthetic data, class imbalance — instead of overselling the result.
DA Freelance Toolkit
Live · built with Claude APIAn AI-powered growth engine for data-analytics freelancers: proposal generator, gig-SEO optimizer, rate calculator, and a client pipeline board — API key kept server-side, never exposed to the browser.
Data Cleaning Projects
Freelance portfolioThree real cleanup jobs — B2B contact deduplication for CRM import, workforce data filtering, and retail sales normalization — each with the messy input and the clean, audit-ready output.
Hosted AML Monitoring API
The 6-rule engine from the toolkit, as a drop-in API endpoint — send a transaction, get a risk score back. No infra to run yourself.
