Mid-Level Software Engineer specializing in full-stack, cloud, and mobile development

Buffalo, NY4y exp

“Backend engineer with open-source web3.js contributions focused on preventing costly smart-contract execution failures, plus hands-on blockchain startup experience scaling an NFT mint from a test EC2 setup to AWS Lambda/API Gateway under extreme concurrency. Built a multiplayer backend improving tick rate from 40 Hz to 105 Hz using UDP, containerization, and Kubernetes, and has healthcare production support experience across 10+ apps. Also publishes IEEE research papers and produces developer-friendly documentation that accelerates team adoption.”

“Unity/C# developer with hands-on Meta Quest shipping experience from Wren Kitchens, building a VR kitchen scale visualiser and solving tricky URP/HDRP cross-pipeline rendering issues by creating internal shader/asset management utilities. Also has solo Unity game experience including an Android/Google Play release and game jam prototyping, plus side-project work using Python/PyTorch for predictive modeling.”

“LLM/agentic AI builder who deployed a production ITSM automation agent on Google ADK integrating ServiceNow and FreshService, with strong safety guardrails (human-approval gating and runbook-only command execution) and rigorous evaluation (500 synthetic tickets; 80%+ false-positive reduction). Also partnered with finance to deliver an AI agent that automated invoice/SOW retrieval and monthly reporting to account managers, reducing manual back-and-forth.”

They also have hands-on experience choosing different agents based on task requirements and serving as an admin for AI tool access.”

“Frontend engineer with hands-on experience building a production crime analysis mapping dashboard for public safety operations using React, TypeScript, and Leaflet. Stands out for combining geospatial visualization, performance tuning at scale, and UX design for dense operational data in a sensitive, compliance-oriented environment.”

“Full-stack engineer with hands-on experience shipping multiple AI-powered products, including donor recommendation systems, RAG-based document Q&A, and cybersecurity threat analysis tools. Stands out for combining TypeScript/React and backend API development with practical LLM evaluation, grounding, and production optimization—driving measurable outcomes like 30% higher donor engagement and 87% answer accuracy under 2-second latency.”

“Backend-focused engineer who built a Python-based automation system leveraging Gemini AI and prompt-driven PDF field extraction to replace a previously manual third-party workflow. Drove stakeholder alignment around accuracy/acceptance thresholds and added production-minded safeguards like graceful failure handling and backup model contingencies.”

“Unity lead developer who built a turn-based soccer game (Soccer Glory/Score Hero-like) with complex in-air ball simulation, AI reactions, and animation handling, then scaled production by creating an in-editor level/animation authoring tool that saves to JSON and shifted level setup from devs to designers. Strong multiplayer background across Photon PUN, Mirror, UNet, and Socket.IO, including a 100-user metaverse room and practical approaches to authoritative simulation and VR/mobile performance optimization (Meta Quest 90 FPS).”
