At TCS, improved a healthcare scheduling platform by diagnosing SQL/server bottlenecks and redesigning database + caching, cutting appointment load times by ~40% and reducing support complaints.”

“Software engineer with experience at Wipro Technologies and Wells Fargo building React-based SPAs, reusable component libraries, and developer documentation. Demonstrated strong performance engineering (React.memo, list virtualization, code splitting) with reported >50% rendering-time improvement, plus hands-on production support by diagnosing API outages via monitoring/logs and implementing traffic/server fixes. Comfortable leading workstreams in fast-changing environments using Kanban and tight stakeholder feedback loops.”

“Full-stack developer with strong cloud/on-prem focus (AWS, VPC networking) who has improved production reliability by bringing manually created IAM/security group resources under Terraform and standardizing environments. Demonstrated end-to-end troubleshooting across app + infrastructure + networking (traffic capture revealed proxy response truncation) and delivered Python-based monitoring/reporting enhancements that improved ops visibility and turnaround.”

“Customer-facing technical professional with experience spanning engineering and product who advises on application security tradeoffs (threat modeling, API/auth risks, SOC2 mapping) and drives pragmatic remediation plans. Hands-on with Kubernetes/CI-CD agent integrations, secrets management, and log-driven troubleshooting; documented and escalated complex customer environment issues and reported a 40% reduction in bug reporting through workflow automation.”

“UE5 gameplay scripter who built a player-facing skill tree for a third-person shooter end-to-end (icons in Illustrator, UI animations, Blueprint behaviors, HLSL shader effects) and migrated the system from Data Assets to Data Tables to improve maintainability and designer-friendly balancing. Also implemented modular weapon logic via base classes, playtest-driven tuning, and refactored broken UI flows into a centralized UI manager with QA-focused debug unlock flags.”

“UE5 gameplay scripter/system designer with shipped experience on Killing Floor 3, owning Blueprint-driven destruction/physics props and trap features end-to-end, including replication, performance optimization, and QA workflows. Also built a one-click light auto-generation tool on Maneater that reportedly saved the lighting team hundreds of hours, and uses fast test-map prototyping to validate mechanics (e.g., movement systems on Salem).”

“Built and monetized an object-identification app end-to-end (FastAPI backend, HTML/JS frontend, SQLite→Postgres, auth, and an iOS wrapper via Capacitor/Xcode with Apple privacy/policy compliance). Also productionized an AI-native geospatial metadata/QA assistant using LLM+RAG plus deterministic Python validation, measuring impact via time-to-first-pass review and rework rate, and has experience modernizing legacy GIS workflows and delivering across USDA/FEMA-style teams with disciplined Jira-based execution.”
