A detailed look at the systems I've built, ranging from fintech reporting terminals to healthcare data integrations.
Screens ~12,000 US tickers per cycle across batched Google Sheets feeds, computing 10 technical indicators (RSI, MACD, Bollinger Bands, ATR and more) with an automated buy/sell/hold signal engine, a 52-week-high screener, and threshold-based client alerts.
Internal GRC and SOC platform ingesting Microsoft Entra sign-in and audit logs plus vulnerability data for anomaly detection (after-hours access, unusual IPs). Includes CISA SCuBA baseline audits, policy management with PDF export, full IAM lifecycle, and time-limited secret-key logins.
A specialized digital publishing ecosystem for psychological journals. Engineered a multi-tier access model supporting free previews, individual purchases, and premium subscriptions. Implemented dual payment rails: global card payments via Stripe and a localized bank/cheque flow with manual proof verification.
HVAC and home-services platform. Built technician diagnostic wizards for heat pumps and gas furnaces that capture real refrigeration measurements - superheat, subcooling, delta-T, ESP, suction/discharge pressures - with multi-step progressive save and a downloadable PDF diagnostic report, plus a careers portal with resume upload.
A feature-driven real estate platform serving ~2,600 live listings. Worked on core user management with role-based permissions and authentication, plus multi-source API integration for property and agent data synchronization.
Engineered a dynamic healthcare portal focused on data visualization and security. Developed custom UI rendering engines to present complex Lab Results and Medical Invoices retrieved via REST APIs. Implemented specialized script snippets to bridge mobile API compatibility with backend administrative interfaces.
Developed a cross-platform booking engine for automotive services. Managed service control permissions and integrated diverse API services to sync car models, booking slots, and branch availability across mobile and web.
Customized checkout flows, order contract automation, and security hardening for payment gateways across several major Myanmar shops.
A procurement and inventory/stock-management system for a regional power entity (Laravel). Built the purchase-order lifecycle - contracts, supplier management, goods receipt - plus stock request/issue flows across division and township branches, a check/approval workflow, RBAC, and formatted print/PDF document output.
Engineered and audited core components of a commercial shopping mall leasing platform. Managed logic for real-time utility meter processing, variable water billing algorithms, and contract rental schedules. Directed system maintenance, automated reporting workflows, and provided on-site technical integration support.
