Years of hands-on testing experience across mobile, modem, network, and connectivity validation.
Hi, I’m Sagar.
I test what keeps us connected.
Test Engineer with 2+ years of experience in mobile devices, modems, networks, RF, and connectivity validation—now building deeper expertise in software QA and test automation.
role: Software Test Engineer / QA Engineer
domain: Mobile • Modem • Network • RF
technologies: 4G/LTE • 5G NR • UE
toolkit: QXDM • ELT • Wireshark • ADB

Quality is where domain knowledge meets curiosity.
Full-fledged projects delivered with rigorous testing, reporting, and release validation.
Team members coordinated and supported during project delivery and validation cycles.
My testing foundation.
Network & Modem Validation
Hands-on validation of real-device and real-network behavior from registration to end-to-end call flows.
RF & Connectivity Testing
Focused on conformance, performance, carrier aggregation, DSS, and reliable connectivity experiences.
Device & Chipset Platforms
Practical exposure to chipset-based validation, firmware flashing, tracing, and basic log investigation.
QA Tooling & Delivery
Structured testing, regression validation, clear bug reporting, and productive developer coordination.
From specialized testing to software quality engineering.
Mobile & Network QA
Applying deep modem, RF, chipset, and connectivity knowledge to deliver dependable mobile experiences.
Automation Skills
Strengthening Python, Playwright, software testing fundamentals, web QA, and API testing concepts.
Quality Engineering
Moving toward Software QA, Test Automation, Mobile Automation, and suitable SDET opportunities.
Building automation capability with intention.
Featured project case studies.
Full write-ups of the projects I'm building to demonstrate testing and automation skill, not just a link to a repo — objective, approach, tools, and outcome for each.
PROJECT / 01Playwright Web Automation Framework
Playwright Web Automation Framework
Objective
Build a maintainable end-to-end regression suite for a sample web app instead of one-off scripts.
Approach
Page Object Model to isolate locators from test logic; data-driven test cases; CI-friendly config.
Tools
Playwright, TypeScript, GitHub Actions, Allure reporting
Outcome
Screenshots and trace capture on failure, HTML test report, and a suite that runs on every push.
PROJECT / 02Python API Test Suite
Python API Test Suite
Objective
Validate a REST API's core contract — happy paths, edge cases, and error handling — without a UI.
Approach
Structured test cases with clear pre-conditions and assertions; fixtures for reusable test data.
Tools
Python, pytest, requests, JSON schema validation
Outcome
A documented suite covering status codes, payload shape, and negative scenarios with readable reports.
PROJECT / 03Mobile QA Case Study
Mobile QA Case Study
Objective
Show, publicly and without confidential data, how I actually test a mobile device end to end.
Approach
Sanitized test scenarios covering attach/detach, network switching, and connectivity edge cases.
Tools
ADB, QXDM-style log review (sanitized), a defect-reporting template
Outcome
A shareable test plan, a sample defect report, and a short recording of the test session.

Verified learning, not just claimed learning.
Nothing completed yet — this section stays empty of real cards until a certification is actually earned and verifiable. Currently studying toward:
Sanitized test artefacts.
Real examples of how I document testing work — no confidential or employer-owned data, ever.
