Work History

Things Worked On + Places Worked At


PHP7 / Node.js / Python3 Developer

[ SHORT TERM 1099 REMOTE IC ] Work included development of highly accurate website mirroring and screenshot tools using PHP7 CLI , wget, HTTRACK, screenshot APIs, Node.js (with Google’s Puppeteer headless chrome project), and Python (with Selenium headless browser project). Built high-performance multi-process website link crawler that processed website mirrors and screenshot by actually “clicking” each link on every page, recursively, and not by simply scraping the href’s and thus missing all the JS-based links/buttons that many modern websites currently use.

Screenshots for both mobile and desktop browsers were provided by submitting the click-crawled URL list to the Browshot API and then polling the API waiting for results to be available. Created python 3 code for basic working Selenium-based crawler is available on my Github repos.

Lead PHP7 Developer / OO Application Architect

[ 1099 REMOTE IC ] Work included object-oriented (OO) MVC-based design and PHP7 development of the enterprise internal webapp “ATSCall” that dynamically and seamlessly collected CDR (call detail records) tables from remote CentOS 7 and Microsoft Server 2016 Asterisk PBX systems using both MySQL and SQL Server databases, to a local MariaDB database that was being used for reporting and secure API access.

Using state-of-the-art UX features like Bootstrap 4 datatables, drag-n-drop data mapping, and OAuth 2 user validation, the entire integrated system replaced 3 different unoptimized, buggy programs, and was saving 4x the overall cost and speeding API data access by over 4 hours.

Led the enterprise infrastructure team for the development of APIs for an end-to-end integration of services for SaaS layers. Consolidated CDR data was published through a high-performance REST API, built with PHP7 using the same self-engineered rapid application development (RAD) MVC framework used for the CDR integrations. Developed nonce/secret key security to allow only authorized users access to sensitive billing and call duration data. Optimized queries over large 100M+ row tables for almost instantaneous response times.

Configured and successfully implemented live internet-facing Windows Server 2016 Apache2 server with Microsoft SQL Server backend database. Full HTTPS was achieved using locally generated test and CA generated production-ready certs and .PEM files. Installed somewhat hard-to-find working ODBC SQL Server drivers for Apache2.

  • Mentored in house developers and led adoption of best practices for development team.

  • Identified and troubleshot issues then documented solutions and QA procedures.

  • Provided technical problem resolution for highly complex problems.

  • Created reusable object-based components for isolated debugging and RAD.

  • Deep integration with in-house enterprise Content Management Systems.

  • Due to the use of RAD framework and efficient OO principles, the scheduled 20-week project was completed in only 11, saving over 50% in labor costs, and received a commendation for being "the first off-site contractor that completed assigned work under budget and ahead of schedule.
