About Balaraj Mandadhi

As a Quality Assurance Leader with 19+ years of experience, I specialize in building high-performing QA organizations, driving automation-first strategies, and ensuring quality is embedded at every stage of the SDLC.At CloudTern Solutions, I lead end-to-end QA initiatives across SaaS and telecom systems — designing scalable automation using Robot Framework, Python, REST/gRPC APIs, MongoDB, and CI/CD pipelines with GitLab. I also spearheaded the automation of end-to-end 4G call simulations using Diameter protocol, improving efficiency and test coverage in telecom validation.Previously, at Oracle, I played a pivotal role as Principal QA Engineer in defining test architecture, managing large-scale enterprise releases, and mentoring engineers to deliver high-impact results. My experience spans enterprise QA, test process optimization, and engineering leadership across complex distributed systems.I’m passionate about transforming traditional QA into Quality Engineering — integrating continuous testing, observability, and automation maturity into agile delivery models. I also focus on coaching teams, implementing quality metrics, and aligning QA strategies with business outcomes.Currently, I’m expanding my leadership capabilities in project management and design thinking, aiming to bring human-centered innovation and measurable quality improvements to every engagement.If your organization is scaling QA excellence or evolving toward cloud-native testing, DevOps integration, or automation-driven delivery, let’s connect.

Experience

1. Lead Engineer

   Cloudtern Solutions

   Mar 2022 — Present

   Core Automation & FrameworkArchitected and maintained a Robot Framework–based automation platform for telecom charging systems, supporting voice, data, roaming, and conference call scenarios.Designed domain-specific Robot keywords to express telecom call flows in business-readable language.Built data-driven automation using structured JSON test inputs with dynamic overrides for zones, roaming, and promotions.Integrated Python-based custom libraries with Robot Framework to extend protocol-level control and validation. Diameter / OCS / Charging Expertise (Key Differentiator)Automated Diameter Credit-Control flows (CCRI, CCRU, CCRT) with full lifecycle validation.Dynamically constructed and mutated Grouped AVPs, including:Multiple-Services-Credit-Control (MSCC)Requested-Service-Unit / Used-Service-UnitIMS, PS, and MMTel AVPsImplemented long-call handling by chunking CCRU requests and sending final CCRT correctly.Validated rating, balance deduction, promotions, and credit limits across call scenarios.Tested conference calls, call forwarding, roaming, and IMS-based charging flows. Database & CDR ValidationPerformed CRM/OCS database validations for generated CDRs.Validated field-level CDR correctness, including: ALEG / BLEG, CallType / CallDirection Volume and duration and Rating and currencyBuilt expected CDR models using dictionary-based validation rather than hardcoded indexes.Automated log inspection and correlation between Diameter flows and backend records. Quality, Debugging & ReliabilityDiagnosed and resolved complex RF expression evaluation issues, type mismatches, and NULL/blank handling.Refactored monolithic test cases into maintainable, modular workflows.Improved test stability by synchronizing protocol timing, DB consistency, and log verification.Acted as technical owner for charging test automation and protocol correctness.
