“Candidate has hands-on experience at Cognizant building production-grade automation and integration solutions across Python ML services, Java microservices, Kafka, and Selenium-based UI testing. They stand out for a strong reliability mindset—covering failure modes, observability, flaky test hardening, and translating ambiguous payment-system business processes into resilient end-to-end automated workflows.”

“Senior software engineer (backend/infra) with hands-on Unity gameplay feature work, including an editor-time page-generation and multilingual pipeline that renders gamebook pages as textures for instant 3D page flips. Combines immersive UX techniques (mask textures + custom shader hover feedback) with strong multiplayer/networking and scalable infrastructure thinking (latency, prediction, security, autoscaling).”

“AI/ML engineer who led Impacter AI’s production deployment of a specialized outreach LLM (CharmedLLM) fine-tuned on GPT-4.1, cutting API costs ~40% while boosting outreach effectiveness ~60%. Built the supporting MLOps and data infrastructure (MLflow, Kubernetes, PySpark, Kafka) and has agentic AI experience from University of Dayton, using LangChain + RAG and vector search (Pinecone) to improve reliability and reduce hallucinations.”

“Frontend engineer with fintech experience who has owned React Native/React + TypeScript architecture end-to-end, including feature-based modularization, reusable component libraries, offline support, and API optimization. Built a heavy analytics dashboard with real-time WebSocket updates and has shipped security-sensitive third-party payment integrations, including rapid post-release fixes via over-the-air updates.”

“Frontend engineer who led a React/TypeScript real-time live-streaming web platform end-to-end, including interactive chat, live polling, and monetization (subscriptions/tipping via Authorize.Net). Built a scalable component system (Tailwind + Storybook) and handled complex real-time state with optimistic UI patterns across WebSocket and server-validated events, collaborating closely with product/design (Figma) and QA in an agile release cadence.”

Principal Real-Time 3D Software Engineer specializing in Unity/Unreal simulation and HMI

Dubai, UAE16y exp

“Gameplay-focused Unity developer who prioritizes tight, fair-feeling controls—implemented a custom raycast-based character movement system (avoiding Unity physics) to make platforming more deterministic and difficulty tuning more reliable. Has prototyped multiplayer in both Unity (Photon tic-tac-toe replication prototype) and Unreal Engine (shared workshop/crafting environment), and actively uses AI tools (Copilot + asset generation) to speed prototyping and documentation.”
