OBJECTIVE: QA Test Engineer
SUMMARY: Highly motivated QA Test Engineer with attention to detail and over 13 years of experience in Manual and Automated testing across different environments. I have conducted E2E testing in Black-Box and White-Box scenarios. Over those 13 years 6 years of them have been working remotely. I am an expert in executing Functional, Integration, System, Smoke/Sanity, Unit, UAT and Regression Testing to ensure product stability and reliability, with a proven track record in bug management using JIRA, collaborating with cross-functional teams to deliver mission-critical software in Agile settings. I have worked in Production and Dev environments with different configuration to ensure product is stable across the board. I have worked most recently testing UI, and backend of cable boxes for Charter communication. I also worked on T-Mobile project testing UI on T-Mobile boxes and Android device. I have experience using AI agents for coding and debugging like Claude Code and Codex.

Test Engineer/Systems Integrator
Manually tested UI in Dev/Eng/Release builds. Also as part of this testing I was responsible for running automated tests where they could be used.
Flashed new FW images onto OTT Set-top-boxes and verified bootup process.
Retested debug builds for developers and assisting in collecting and analyzing of logs, dumps and took video on-site and remotely.
Validated UI bugs fixed on STB to ensure issue is resolved before migrating code to release builds.
I have worked testing local Ad insertion that is added during live TV depending of geographic location.
I also have experience validation data collection by checking workflow from STB to .csv files that where collected in backed server.
Ran manual front-end UATs on STB UI during integration, regression, smoke, and release testing.
Worked with Arris and Cisco headends, DAC, TSBrodcasters, DVR, IPV6, Closed Caption, EAS, PPV, VOD, and billing systems. I tested video with DRM (Widevine and PlayReady) with H,264 and H265 codecs as well as AAC and Dolby Audio over QAM and IP systems.
Responsible for demoing new features to management and product stake holders on-site of our proprietary software. I was responsible for configuring STBs to be used during demos and working with customer engineers to provision demo boxes to work with Dev environments.
Reproducing of customer reported issues to determine if it’s was a bug or environmental issue.
Created Confluence wiki pages for testing team which included steps to load builds to legacy and new generation STBs. Process of editing JSON, XML, and other configuration files.
Worked with Linux servers, SVN, and Oracle database. During testing I would have to edit JSON or XML files to test new feature that would have to be enabled through configuration files. Files would also have to be committed into SVN in order to be downloaded during booting process. I would also have to edit paths in Linux based system files in order to be redirected to correct location during download. Also works with DB to verify recorded assets using SQL queries for date validation of saving, updating, or removing during testing.
Help validate new build after new code was implemented to CI/CD pipeline using Jenkins. Also executed automated Python tests on STBs that were connected to Dev environments to catch bugs before releasing production or engineering builds to customers.
Created/maintained test cases from product requirement documentation. Also worked with developers to come up with new watchdog tests to execute on STBs to find any issues that may have entered Dev environment during testing from 3th party vendors systems.
Worked with 3th party vendors to validated there fixes when issues were found on there side during testing. As part of this process I had to help troubleshoot to find the root cause.
Opened tickets for bugs/defects using JIRA and keeping track until issues were resolved or requirements changes.
I was responsible for helping train new QA testers on how to properly install new build on different hardware types like Arris, Humax, Technicolor, and Motorola STBs.
Helped with lab setup and conducted maintenance of equipment. Part of keeping the lab in working order I had to run watchdog automated tests to detect hardware issues and networking problems with environment to get them ready for testing.
Manually tested T-Mobile TV app on different boxes and communicated with overseas team to get bugs resolved.
Wrote test cases from requirements documentation and tested web application with multiple pages, buttons, dropdowns, text fields and DB integration. Used Playwright with typescript to create tests and helped with creation of Framework including POMs, and fixtures . I have experience testing APIs with Postman and Pytest. I also have experience using AI agents for coding and debugging. Please check my GitHub repo.
Tested cases that aligned with Section 508 compliance and accessibility standards like “Guide Narration”, “Close Caption”, and “DVS”.
