Network Support Engineer

Annalect – Hyderabad, India Nov 2021 – Jul 2023

• Performed network-integrated ad validation on the ADZU platform using TCP/IP and browser tools, identifying routing flaws that cut failed campaign loads by 18% across client regions.

• Resolved over 100 DNS lookup failures and SSL mismatches by collaborating with backend teams, which improved secure ad delivery rates and reduced escalation volume.

• Tested REST APIs for ad campaign triggers and role-based access using Postman, flagging latency and payload bugs that contributed to 99.9% uptime after patch release.

• Captured and reported firewall timeout errors through Wireshark and JIRA, accelerating the implementation of tighter transport rules and reducing session dropouts by 25%.

• Designed automation scripts using Selenium and TestNG for login and form validations, achieving a 40% reduction in manual test effort and improved RBAC checks.

• Partnered with infrastructure teams to inspect permission issues in isolated VLANs, helping reduce cross-network authentication failures in production by 30%.

• Conducted multi-platform ad testing via remote desktop tools and VPN configurations, exposing session integrity flaws across Android and iOS environments.

• Organized test scenarios using Eclipse and Maven, aligning with modular POM practices and ensuring consistent test traceability in Agile Jira workflows.

PROJECTS

Ad Campaign Routing & Delivery Validation

• Emulated end-to-end client-server routing to assess ad delivery across segmented networks, improving routing accuracy and campaign success rates.

• Detected proxy misconfigurations and NAT table errors, leading to a 25% reduction in delivery failures across targeted user segments.

• Documented API timeout and header mismatch issues, contributing to stable payload delivery and enhanced API response handling. API & Endpoint Security Testing for Ad Operations

• Validated API endpoints for campaign workflows and access control, ensuring secure data handling and reducing authentication loopholes.

• Conducted negative testing with invalid tokens and expired credentials to verify endpoint security and prevent unauthorized access.

• Identified payload limitations and optimized response handling, lowering critical API error rates by 30% across environments. Automation of Network Login Verification Flows

• Built automation scripts for login verification workflows simulating VPN-authenticated access and tested across multiple user roles.

• Prioritized test execution for session-based validations and generated detailed login session and response time reports.

• Verified multi-factor authentication, password policies, and timeout configurations during simulated load-based traffic sessions. Student Network Usage Insights Dashboard

• Designed dashboards to visualize login activity, bandwidth usage, and time-of-day peaks using network access log simulations.

• Queried structured datasets to calculate session duration, peak loads, and connection trends across multiple departments.

• Modeled KPIs reflecting usage anomalies and risk scores, mimicking NOC-level monitoring dashboards for proactive analysis. EDUCATION
