What I do
Systems that connect, quietly.
For the past two years I've designed, built and kept alive enterprise CRM and ERP applications on PHP, Laravel, CodeIgniter 4 and MySQL — owning features end‑to‑end, from sitting with a client to work out what they actually need, through architecture and implementation, to staying reachable once it's live in production.
Lately that's meant teaching backend systems to understand plain language: parsing WhatsApp messages into structured transactions, and translating natural‑language requests into validated, injection‑safe SQL. I like the parts of engineering most people skip past — requirement gathering, data modelling, the quiet plumbing that makes an integration actually reliable.

Featured work
Projects I'd talk your ear off about
A multi‑user expense tracker with admin‑approved signup and user‑scoped data access, built on Laravel. Messages sent to WhatsApp are parsed by an LLM structured‑output layer into categorized credit/debit records, processed asynchronously through Laravel jobs and queues, with scheduled daily and weekly spending summaries sent back over WhatsApp — while the dashboard keeps all business logic deterministic and database‑backed.
A complete School ERP with a custom AJAX‑driven, SPA‑style navigation engine built directly on top of CodeIgniter 4 — no frontend framework involved. Covers student management, employee management, attendance, academic management and role‑based dashboards, with dynamic view loading, browser history and state preservation, plus client‑side caching tuned to keep page transitions feeling native.
