Various projects, based on Jira tickets and organizational requirements. Current project is implementing a POC for a large-scale automated firewall using openstack and calico.- Implemented an automated firewall POC with calico/felix/etcd (Linux).- Wrote glue code with team to connect policy/rules/intent database with automated firewall (Python).- Rewrote network information query system to be faster/more reliable (Python/tornado). - Replaced multi-process model with async/await coroutines. - Replaced django with tornado. - Converted to buildout (similar to virtualenv). - Wrote salt deployment recipe (including haproxy).- Use agile development process: scrum/jira/standups.

Main project: administrator control panel for the i1 computational storage server.- 50,000+ lines of JavaScript code (Ember.js and Node.js).- Rewrote client/server and server/IPC code into a proper RPC implementation.- Migrated JavaScript codebase from ES5 to ES7 for efficiency and easy readability.- Implemented new designs from graphics artist (HTML5, CSS, JavaScript).- Utilized both MySQL and MongoDB for data persistence and retrieval.- Worked closely with Quality Assurance to provide optimal user experience.- Met with customers to get UI feedback and gather feature and improvement requests.- Wrote C code to interface with low-level linux and libvirt libraries.- Fixed bugs in upstream open-source github.com projects. (JavaScript)- Took charge of interviewing full-time and internship programming candidates.- Mentored during summer 2017 internship.- Worked with intern to refactor 2,000+ lines of php code into Node.js code.- Implemented several new features to meet business requirements and customer requests.- Closed security holes by auditing other team members’ code. (JavaScript / Python / C++)- Designed and coded secure software update system and software licensing system. (JavaScript / Node.js)- Read through parts of the linux kernel source code to determine cause of undocumented behavior. (C)- Implemented a clean git workflow for the UI/Node.js team.- Assisted coworkers on git usage, secure software development, gnu/linux internals, and system architecture.

Programming:- Wrote 9,000+ lines of Python 2.7 and 4,200+ lines of Javascript automation program by myself. In addition to the complex backend, I built an advanced AJAX web GUI that's so easy to use, hardly any documentation is needed. It allows customer support/delivery personel to quickly build and tear down customer environments for testing. The program handles AIX/P-series servers (LPARs), storage LUN creation and mapping, network VLAN setup on Cisco switches, and auto-generated documentation for customer and support personnel use. It parses human-readable excel (.xls) files into usable data. Large builds with 90+ servers can be built automatically in minutes.- Work with IBM RS automation team on various projects and offerings.- Wrote a program in C (283 lines) to automatically extract customer image tapes.- Wrote a ncurses Python 2.7 NIM menu wrapper program (759 lines). This was to provide customer support personnel with an easy way to allocate and load AIX images and customer AIX mksysb images. UI has arrow key navigation as well as typing desired menu items, and a file browser.- Wrote many other small korn/bash shell scripts and perl utilities to simplify customer support workAdministration/DevOps:- Primary sysadmin on 7 AIX NIM LPARs, 2 AIX WPARs, 1 FreeBSD, and 3 linux servers all used internally by the core support team- Basic Cisco switch knowledge (both SAN and network)- Patch/upgrade servers- Maintain RBAC security- Work with Wintel, Sun, DEC, SAN, and network teamsCustomer Support:- Provide tier-2 support to corporate customers- Assist customer sysadmins with AIX, linux, SAN, and networking issues- On-call; on-site and remote supportLeadership:- Train both seasoned sysadmins and beginning sysops in their new job roles- Organize team during time-critical issues and prioritize/delegate- Sterling Forest AIX subject matter expert- Backup AIX team leader for Sterling Forest
