Design and build a secure, real-time tracking system to monitor fruit container movements (in and out) for facility operations at S&F Produce Group, ensuring accurate inventory flow and traceability.

Architected the backend with Laravel, leveraging its robust authentication and request handling. Built the user interface in React.js for high responsiveness. Set up, deployed, and managed the complete application infrastructure and DevOps pipelines on AWS.

Develop a reliable warehouse inventory management application for S&F Produce Group to track material flow, stock levels, and storage locations with strong data integrity.

Constructed a database-backed inventory log on Laravel APIs, paired with a React.js interface for quick staff operations. Managed the deployment architecture on AWS and established continuous delivery pipelines.

Support and extend a growing music streaming platform — handling bug fixes across a complex codebase, shipping new features under tight timelines, and maintaining platform stability as the user base grows.

Diagnosed and resolved production bugs systematically, tracing issues through the full stack rather than patching surface symptoms. Delivered new features with minimal regression by writing against the existing architecture's grain rather than introducing new patterns unnecessarily.

Build a full communication platform integrating Twilio's voice calling and SMS APIs — handling call routing, message queuing, delivery status tracking, and webhook event processing reliably at scale.

Designed a Node.js event-driven backend that handles Twilio webhooks idempotently. Built robust retry logic and status reconciliation to handle the edge cases Twilio's async model creates.

Maintain and continuously enhance a live enterprise dental staffing platform used by dental offices and professionals for temporary and permanent placements — balancing new feature delivery against zero-disruption stability over 3+ years.

Developed and delivered new features, enhancements, and production fixes across the platform. Designed and optimised backend functionality, database queries, and application workflows to improve performance. Investigated and resolved production issues with minimal user disruption. Collaborated with stakeholders throughout the full development lifecycle.

Deliver a complete personal finance tracking application independently — covering backend API, database design, authentication, and frontend — as one of the first independent projects in my career.

Built end-to-end using PHP/Laravel for the backend and a clean frontend interface. Established my own development workflow for independent ownership: requirements → schema → API → frontend → QA → deployment.

Provide ongoing engineering support for TPC — triaging bugs, fixing production issues, and shipping new features without disrupting an active user base.

Established a structured approach to each bug report: reproduce first, understand root cause, fix at the source rather than at the symptom. New features scoped carefully to avoid scope creep and regression.

Build a platform that connects users with local handymen for on-demand tasks and services — similar to a handyman marketplace — for a Germany-based client with an existing developer team.

Worked as the individual developer representing enAct, directly embedded with the Germany client team. Handled daily meetings with the client and their in-house developers, managed technical communication, and delivered features aligned with their roadmap. Maintained clear documentation and ensured smooth cross-team coordination across time zones.
