WORK EXPERIENCE
Kevuru Games
April 2024 – Present

Skilled in test design optimization, defect lifecycle management, and API validation using Postman.
Participated in testing complex systems including e-commerce platforms, mobile utilities, crypto simulators,
live data applications, and multiplayer games (Unity/Unreal Engine).
Capable of driving test strategy, analyzing risks, creating reusable documentation, and collaborating
with cross-functional teams. Successfully mentored junior QA engineers and improved onboarding processes.
Focused on delivering stability, transparency, and measurable quality results. Test Process Organization:
Hands-on experience in planning, implementing, and optimizing the test process from test strategy to
execution and reporting. Created test plans, traceability matrices, reusable test cases, and ensured
consistent alignment with project requirements and development cycles.
Defect Management: Full lifecycle ownership of bug tracking including identification, classification,
prioritization, root cause analysis, triage participation, and closure. Applied severity/priority classification
according to ISTQB standards and contributed to continuous improvement through retrospective reviews.
Stakeholder Communication: Actively collaborated with cross-functional teams including developers,
project managers, designers, and clients. Delivered structured QA reports, discussed quality risks, clarified
requirements early, and facilitated knowledge sharing through Confluence and direct sync meetings.

Key Project Experience:
Multiplayer Online RPG Shooter (Unreal Engine):
• Tested combat mechanics, matchmaking logic, user interface flows, online session stability, NFT asset
management, and streaming systems. Conducted regression, exploratory, and performance testing
across PC and console environments.
Interactive Visual Novel (Unity):
• Focused on testing branching dialogue trees, animation syncing, interactive event logic, localization
coverage, and user feedback flow. Conducted UI/UX, localization, and compatibility testing across mobile
and tablet devices.
Casual Mobile Game (Unity):
• Verified core game loop mechanics, reward system logic, idle mechanics, ad integration, in-app
purchases, and push notification delivery. Conducted smoke, regression, and usability testing across
Android and iOS.
Cryptocurrency Exchange Simulator:
• Focused on financial transaction flow, data accuracy, REST API stability, backend load behavior, and edge
case validation. Used Postman and Chrome DevTools to verify transaction simulations under various
network conditions.
Live Data Aggregation Website for Brokerage Integration:
• Verified accuracy and integrity of imported market data from multiple sources, which was later used for
simulations. Validated REST APIs, data rendering, filter logic, and responsive layout behavior.
AI-Powered Productivity Application:
• Tested user input recognition, AI-generated outputs, performance under load, latency, intent-matching
logic, and fallback responses. Used exploratory testing, edge case analysis, and usability evaluation.
Streaming-Based Sales & Matchmaking Platform:
• Tested live stream stability, real-time matchmaking behavior, data synchronization, media delivery, and
session continuity. Conducted load and performance testing using JMeter.
Web Projects (CRM, eCommerce, Landing Pages):
• Performed cross-browser compatibility testing, responsive layout verification, checkout/payment flow
checks, localization validation, and functional regression.

KEY ACHIEVEMENTS
• Improved QA onboarding pipeline, reducing ramp-up time by 30% by introducing templates, mentoring
practices, and knowledge base in Confluence.
• Reduced release-blocking defects by 25% on a AAA-level Unreal Engine project by integrating early risk
identification and targeted exploratory testing.
• Increased test coverage by 30% using test design techniques: boundary value analysis, pairwise testing,
and decision tables.
• Developed reusable API test collections in Postman for financial simulation systems and real-time data
validation workflows.
• Mentored and supported 3+ junior QA engineers across multiple projects, leading to improved team
autonomy and reporting quality.

Middle QA Engineer | March 2025 – Present
• Led QA activities for a competitive PvP multiplayer shooter (Unreal Engine).
• Tested combat mechanics, weapon balancing, inventory, matchmaking logic, cross-platform
compatibility, and NFT integration.
• Developed test plans, test cases and research charters.
• Built and maintained Postman API regression suites for game backend validation.
• Validated real-time data sync and session stability for multiplayer environments.
