Building SmartAutomation Platforms
for reliable delivery
Automation Framework Architecture
Designing scalable automation frameworks for web, API, and integration layers using Playwright, Selenium, and Pytest. Built for reliability, maintainability, and long-term growth.
Workflow Automation for Teams
Automating end-to-end engineering workflows, including releases, data setup, environment checks, and reporting, to reduce manual effort and accelerate delivery.
API & System Automation
Automating validation of business logic, data flows, and system integrations across distributed systems to prove stability beyond the UI layer.
CI/CD Automation & Release Gates
Embedding automated checks and release gates into CI/CD pipelines using Jenkins, GitHub Actions, or Buildkite to catch risk on every code change.
AI-Driven Automation & Signal Analysis
Applying AI-assisted automation to optimise coverage, analyse logs, detect anomalies, and support smarter release decisions.
SDET Strategy & Technical Coaching
Defining automation roadmaps, test strategies, and delivery metrics to help teams scale automation, reduce defect leakage, and mature engineering practices.
Focused on automation that removes manual bottlenecks and scales engineering teams.
Available for senior SDET, automation architecture, and AI-driven workflow automation engagements. Let’s talk.
