Professional Summary

Quality Engineer who builds test automation from the ground up and scales reliability across fast-growing, cloud-connected platforms. Brings 7+ years across the full SDLC — 4+ in test automation — architecting automation frameworks, driving shift-left quality into CI/CD pipelines, and leading system integration testing for confident, repeatable releases. A quick study who earned advanced degrees across three countries before ramping into EV charging (OCPP/EVSE) and AWS microservices to help Siemens’ Depot360 AI platform scale across six global markets — and applies that adaptability to any complex domain.

Professional Experience

Quality Assurance Specialist

Siemens Canada Limited, Fredericton, NB, CanadaJune 2023 - August 2026

Owned end-to-end test automation for Depot360 AI — Siemens’ AWS-hosted, AI/ML-powered EV fleet platform — as it scaled to six global markets. Built the Cypress framework from scratch and led system integration testing for a microservices backend within a 40+ person, SAFe® Agile team.

  • Built 500+ Cypress tests to ~95% automation coverage across OCPP, Geotab telematics, and Home Reimbursement, supporting all 6 market launches.
  • Led system integration testing for the microservices backend, refining user stories with PMs and developers to cut defect escape rate ~60%.
  • Re-engineered the automated regression pipeline from 3 hrs to 45 min, so the full suite could run daily and surface issues fast.
  • Introduced severity-based triage for 300+ JIRA tickets per PI, giving PMs clearer release-readiness signals.
  • Led root-cause analysis and regression testing on production incidents with NOC support, reducing recurrence 35%.
  • Authored the UI/API test framework and Test Plan for Home Reimbursement and mentored two junior testers, cutting post-release defects ~70%.

Software Tester (Co-op)

Siemens Canada Limited, Fredericton, NB, CanadaSeptember 2021 - September 2022

Tested Siemens’ Decentralized Energy Management System (DEMS) — a smart-grid platform that monitors and optimizes distributed energy resources such as solar, wind, battery storage, and EV chargers. Built manual and automated suites for its DNP3-based control-system components alongside developers and technical leads.

  • Ramped quickly on the complex DNP3 Secure Authentication protocol and its test harness, clearing a full 200+ test suite across control modules and signal dispatchers ahead of schedule.
  • Adopted and extended a test-data-automation framework other QEs had sidestepped, adding reusable scripts that cut repetitive setup and standardized 100+ test documents.
  • Partnered with 8+ developers and leads on root-cause analysis, introducing clearer defect documentation and troubleshooting workflows.
  • Picked up Linux, Docker, and Prometheus/Grafana to stand up monitoring and build tooling from source — earning written recognition from leadership as one of the term’s most productive co-ops.

Founder (Web/Graphic Designer)

P.A.G Fine Art Reproduction Services / Chop30 Online Printing Services, Kerman, Kerman, IranOctober 2017 - October 2020

Founded and ran two online printing and fine-art reproduction businesses, building the e-commerce platforms, branding, and digital marketing end to end.

  • Built an e-commerce platform and digital art marketplace of 1,000+ artworks, improving ordering efficiency 80%.
  • Grew to 500+ active clients in the first year through improved online services and product presentation.
  • Designed responsive websites, CMS workflows, and branding for a consistent presence across both businesses.
  • Ran end-to-end operations — development, vendor coordination, and contracts — and registered the Chop30 brand in 2018.

Personal Projects & Hobbies

A hands-on builder who brings an engineer’s problem-solving and attention to detail to personal projects — here are a few of my latest:

  • Revived a dead secondhand boat trolling motor by rebuilding its control system from scratch with a custom wireless remote and PWM-based speed controller, restoring smooth variable-speed control.
  • Turned a $10 secondhand Lenovo all-in-one into a full Linux-based Home Assistant OS hub that controls the whole house — thermostats, TVs, lights, and Alexa and Apple devices — running automations like Zigbee radar-motion-triggered stairway lighting, fireplace-on when the living room is occupied, and dimming the ceiling light when the TV plays to remove screen glare.
  • Reverse-engineered out-of-print board games and repurposed worn vintage Persian rugs into playable reproductions and framed wall art, blending creativity with craftsmanship.
