End-to-end test automation — UI, API & Performance Client-awarded for zero-defect delivery at UBS

Hi, I am Sai Sharanya Rangineni. I ensure software works the way it should, reliably, efficiently, and at scale. I specialise in automation testing with 4.5+ years of experience, building robust test frameworks, and helping teams release with confidence. My focus is on catching issues early, improving quality, and reducing manual effort through smart automation.

Featured Projects

These projects are built for portfolio and demonstration purposes. No proprietary or company-related information, code, or projects have been used. All tests run against publicly available demo applications.

Playwright • TypeScript

E2E Testing Framework — Playwright

Problem Manual regression testing was slow, error-prone, and couldn't keep pace with weekly releases.
Approach Built a Playwright + TypeScript framework with Page Object Model, API mocking, parallel execution, and visual regression.
Impact ~85% reduction in regression cycle time — from hours of manual effort to minutes with full CI/CD integration, parallel execution, and automated HTML reporting.
TypeScript POM CI/CD Visual Regression
Selenium • Java • Cucumber

BDD Automation Framework — Selenium

Problem Testing across browsers was fragmented with different scripts, inconsistent results, and no shared test language with the business.
Approach Created a scalable Selenium + Cucumber BDD framework with data-driven tests, cross-browser execution, Allure reporting, and Docker-based runs.
Impact Unified test language for dev and QA, enabling non-technical stakeholders to review scenarios. 30+ UI regression tests, API contract validations, and JMeter load tests — saving ~6 manual hours per release cycle at Roche.

Postman • Newman • REST Assured

API Testing Suite

Problem API changes were breaking downstream integrations without warning because no systematic validation existed.
Approach Built a comprehensive suite with JSON schema validation, chained request flows, environment-based configs, and Newman CLI for CI.
Impact Caught breaking API changes pre-deployment with automated GitHub Actions pipeline, eliminating manual validation on every push.
REST API Newman GitHub Actions JSON Schema
JMeter • Performance

Performance Testing Dashboard

Problem No visibility into system performance under peak load. SLA breaches were discovered only in production.
Approach Designed JMeter test plans with HTML dashboards, SLA threshold validation, load profiles for peak and sustained traffic, plus Python-based analysis.
Impact Enabled proactive SLA monitoring before release so teams could identify bottlenecks during pre-prod load tests instead of after go-live.
JMeter Python SLA HTML Reports

What I Bring to Your Team

🧩

Problem-First Thinker

I don't just write tests. I understand what can break, why it matters, and how to prevent it systematically.

🏗️

Clean, Scalable Code

Frameworks built for growth with Page Object patterns, reusable components, and CI-ready from day one.

🚀

Quick to Adapt

Moved from capital markets to pharma to healthcare, ramping up on new domains and tech stacks fast.

🤝

Ownership Mindset

Recognised by clients at UBS for quality. I take end-to-end responsibility, not just execution but outcomes.

My Journey

I believe great software starts with someone asking: "What could go wrong?"

I started my career fascinated by the idea that a single overlooked edge case could cascade into a real-world failure. That curiosity led me from functional testing at UBS, where I became the go-to person for payment reconciliation, to building full automation frameworks at Roche and Optum. Along the way, I picked up a dual role as a Business Analyst because understanding what we're building matters just as much as testing how it works. Today, I'm drawn to problems that sit at the intersection of reliability and scale. Automation, for me, isn't just about saving time. It's about protecting people's health records, financial transactions, and trust. I'm looking for a team where I can bring this same intensity, grow into performance engineering, and contribute to systems that truly matter.

Testimonials

"During my tenure in Accenture, I got to work with Sharanya for close to 10 months. She is a very sharp and a quick learner. She is a self-motivated team player. She started off as a quality analyst and in a very short span has taken over a role of a business analyst as well. She needs very little guidance, I trust her to work independently on the features assigned and have confidence that she will do a thorough job."
