I build backend systems that scale — clean APIs, real business logic, and production-ready code.

I'm a fullstack developer specializing in backend architecture with Django and Python. I design and build web platforms where the complexity lives in the data model and business rules — role-based access, multi-module systems, real-time data, and production deployments. I'm equally comfortable working across the stack with React when the project demands it.

I gravitate toward problems that require thinking beyond CRUD: permission hierarchies, domain modeling, system integrations, and anything where a wrong schema decision costs weeks.

Django Python Business Logic Finance

A backend-driven system for managing watch sales, inventory, layaways, and financial tracking — designed around real business operations.

• Automatic financial sync: sales, purchases, and layaway payments generate income/expense records
• Inventory lifecycle management tied to business transactions
• Layaway system with partial payments and financial traceability
• Clear separation between commercial logic and financial accounting layer
• Designed to avoid inconsistencies between inventory and finance through service-layer orchestration

Python Django SQLite

University institutions run payroll on spreadsheets and manual processes. Saltix replaces that with a structured, role-driven platform.

• Handles the full payroll lifecycle: campuses → departments → teachers → schedules → attendance → incidents → pay periods → receipts
• Role-based access with separate dashboards for admins and department heads
• Incident and correction workflows built into the attendance module
• Documented end-to-end: 24 functional requirements, risk matrix, ER diagram, component architecture, wireframes, and test cases

Django Python Production

An internal operations platform for managing SIM card inventory and subscriptions — built for and running in production.

• Custom admin panel with user management and permission control
• Business logic for subscription states, SIM lifecycle, and access policies
• Deployed and actively used, not a portfolio demo

Django Sockets Networking JavaScript

Real-time network visibility platform built for infrastructure teams managing multiple devices and VLANs.

• Syslog listener captures and processes live network events
• Port status updates streamed in real time via sockets
• VLAN management interface with dynamic activity dashboard
• Designed around network admin workflows, not generic dashboards
