About Me
Hello! I'm Bathiya Lakruwan
I am a Software Quality Assurance Engineer with hands-on experience in manual testing, automation testing, API validation, data verification, and end-to-end workflow testing across web and mobile applications.
Currently, I work on a Transport and Supply Chain TMS platform, supporting release quality across Job Master, GPS Live Map, Control Tower, Work Orders, Route Optimization, Contracts, Invoicing, reporting, and mobile-assistance workflows. My work includes test planning, RTMs, regression testing, exploratory testing, UAT support, API and MongoDB validation, production issue reproduction, and release-readiness checks.
I build reusable automation and QA-support solutions using Playwright, TypeScript, Selenium, Cypress, Cucumber BDD, Page Object Model, Postman/Newman, Python, SQL, and Excel-based validation tools. I also developed a human-reviewed Smart QA Agent OS prototype to support risk analysis, test design, evidence capture, automation planning, and regression-quality workflows.
My focus is improving product stability, test coverage, data accuracy, and confidence in every release through practical, evidence-based QA.
- Owned end-to-end QA coverage for a Transport and Supply Chain TMS platform across Job Master, GPS Live Map, Work Orders, Route Optimizer, Contracts, Invoicing, Control Tower, platform workflows, reports, and mobile assistance app features.
- Prepared and executed **1,000+ test cases** including RTMs, exploratory scenarios, smoke checks, sanity checks, regression testing, UAT support, and release validation checklists.
- Identified and reported **1,000+** functional, regression, API, GPS/live-map, reporting, data, and production-related **defects** through Jira with clear reproduction steps, severity, evidence, and retest results.
- Designed a reusable Playwright + TypeScript automation architecture using BDD, Page Object Model, fixtures, reusable flow methods, test-data files, API clients, evidence capture, and structured reporting.
- Built API and hybrid automation coverage using Playwright API clients and Postman/Newman collections for authentication checks, response validation, JSON schema checks, negative testing, and API + UI verification.
- Improved backend and data validation coverage by verifying MongoDB behaviour, workflow records, report values, and system-generated outputs against expected business rules.
- Reduced route and optimizer validation effort by **up to 75%** using OSRM and Google Maps API-based comparison workflows for route distance, paths, multi-stop behaviour, and optimizer outputs.
- Reduced customer upload errors by **over 50%** by creating Python and Excel-based validation utilities for bulk data formatting, expected-versus-actual checks, duplicate detection, and common upload issues.
- Performed cross-browser testing on Chrome, Firefox, and Edge, and validated Android workflows for the Haulmatic mobile assistance application.
- Supported Agile delivery through grooming, sprint discussions, retrospectives, defect triage, release reviews, fix verification, and release sign-off support.

QA Tools, Automation & Case Studies
Public-safe QA tools and case studies demonstrating automation, data validation, GPS simulation, route-optimizer validation, release-quality workflows, and AI-assisted QA practices.
All examples use sanitized or fictional data. No production credentials, customer data, proprietary source code, or confidential employer information is included.
Smart QA Agent OS
Human-reviewed AI-assisted QA workflow for requirement analysis, risk identification, test-case drafting, evidence capture, locator investigation, and automation planning. Human QA approval remains required for test cases, defect decisions, locator changes, and release recommendations.
GPS Simulator & Geofence Validation Suite
A controlled GPS testing suite for simulating routes, multiple vehicles, geofence events, playback flows, location updates, and map-based QA scenarios. Built using sanitized examples to demonstrate transport and GPS workflow validation.
Route Optimizer Validation Workbench
An independent QA validation approach for route distance, cost, vehicle suitability, capacity, allocation logic, and operational feasibility. Helps compare optimizer outputs against expected business and transport rules.
Bulk Upload Data Quality Validator
A data-quality workflow for checking bulk-upload files before they enter a system. It detects missing values, invalid formats, duplicate IDs, reference-data issues, and auto-correctable problems while supporting safe synthetic QA test data.
More QA case studies are available in my public portfolio, including Job Master data validation, AI-assisted test design, Jira evidence reporting, and release-readiness workflows.
