About Me

I am a Technical Lead and Senior Developer with more than 20 years of experience designing, modernizing, and scaling software platforms across content, enterprise, and commerce environments.

My strongest value comes from combining deep implementation skill with long-range thinking: I can move from architecture and database design to frontend experience, delivery workflows, and stakeholder alignment without losing momentum.

Teams bring me in when they need someone who can untangle legacy systems, mentor engineers, and translate ambitious business goals into software that is faster to ship, easier to maintain, and built for growth.

Experience

Technical Lead / Senior Developer at ECLARO

2010 - 2025

Primary engineering lead and long-term consultant for Longitude73, partnering closely with US executives, editorial leaders, and product stakeholders.

Over more than 15 years in this engagement, I helped steer the evolution of a legacy publishing platform into a scalable, component-driven ecosystem that could support multiple digital properties without compounding maintenance cost. My role went beyond implementation: I shaped product direction with stakeholders, translated editorial and business goals into technical roadmaps, and established reusable patterns that improved consistency across backend and frontend systems.

The work produced concrete operational gains. I introduced AI-assisted editorial workflows that increased output from one article to ten articles per editor per day, designed geo-targeted content systems with MongoDB to improve content relevance, and pushed for strong performance and accessibility standards that supported SEO and user experience. More recently, I have also been leading cross-platform mobile application development using React Native and modern backend services, extending the same product-minded engineering approach into mobile delivery.

Senior PHP Developer at Optimum Source Inc

Focused on HR software reliability, backend performance, and client-facing feature delivery for a US-based business.

2010

In a shorter but high-responsibility role, I improved usability and reporting performance for HR software while staying close to client communication. It was a practical, delivery-heavy environment that required clear prioritization, fast diagnosis of backend issues, and steady coordination between product needs and technical execution.

Senior PHP Developer at Microsourcing

2008 - 2009

Built and enhanced web applications for international clients with a focus on commerce and marketing workflows.

I worked across client projects where conversion-driven web experiences mattered, improving checkout and search flows while modernizing older modules to support faster campaign execution. The role sharpened my ability to make legacy systems more responsive to business experimentation without destabilizing the underlying platform.

Senior PHP Developer at The Design People

2006 - 2008

Created CMS-driven platforms and reusable frameworks for multiple client websites.

This period established many of the patterns I still use today: modular architecture, repeatable delivery practices, and framework thinking instead of one-off implementation. By designing reusable systems for multiple sites, I helped teams reduce turnaround time and improve scalability from project to project.

Software Engineer at Accenture

2004 - 2006

Contributed to enterprise systems involving PeopleSoft and Oracle CRM.

I started in a structured enterprise environment that grounded me in large-scale SDLC practices, QA discipline, and cross-functional delivery. That foundation still shows up in how I lead projects today: rigorous process where it matters, paired with enough pragmatism to keep teams shipping.

Projects

Platform Modernization

Legacy CMS to Component-Driven Publishing Platform

Led the redesign of a long-running legacy CMS into a modular platform that supported multiple digital properties, standardized content components, and made feature development far less fragile.

Outcome: lower maintenance overhead, faster release cycles, and a platform foundation that could keep evolving instead of being repeatedly patched.

AI Workflow Design

AI-Assisted Editorial Production System

Architected and integrated AI-supported content workflows that fit directly into editorial operations, helping teams produce more without forcing a disruptive process reset.

Outcome: increased editor output from 1 article to 10 articles per day per editor without additional headcount.

Geo-Targeted Discovery

Location-Relevant Content Delivery with MongoDB

Designed geospatial search and content targeting capabilities so users could discover more relevant local information across high-traffic platforms.

Outcome: stronger engagement through better content relevance and a more useful search experience tied to user location.

Mobile Product Delivery

Cross-Platform React Native Application

Currently leading development of a mobile app built with React Native, Expo, and modern backend services, with a focus on onboarding, authentication, and real-time interactions.

Outcome: a modern mobile product foundation that brings the same architectural discipline from web platforms into app delivery.
