ABOUT ME
Hey there, this is Aryan Rajguru!
I'm a Senior studying Computer Science & Engineering at the University of Toledo, with a passion for building intelligent, scalable software using machine learning and AI.
Outside of classroom, I currently work as an IT Systems and Infrastructure Analyst at UTMC, my university's hospital, where I secure and support critical systems in a 24/7, zero-downtime environment. Beyond academics, I build AI agents, cloud-native apps, segmented networks, and even PLC-controlled pump stations.

Aug 2025 - Present
- Engineered Imprivata RBAC/SSO workflows across 500+ shared clinical workstations, mirroring operator-console and HMI security from OT settings.
- Hardened and patched 500+ endpoints under strict change control, with Tier-2/3 break-fix support and root-cause analysis across Epic EHR, Microsoft 365, and the network.
- Enforced HIPAA/NIST-aligned compliance through vulnerability audits, privilege reviews, and NIST SP 800-88 asset decommissioning.
IT Systems and Infrastructure Analyst - Level 1
@University of Toledo Medical Campus
Dec 2024 - Aug 2025
- Diagnosed and resolved 15+ software, hardware, and network incidents a week, configuring and imaging machines and managing access with Intune and Active Directory.
- Cut login-related escalations by 80% by troubleshooting Imprivata single sign-on on shared clinical workstations.
- Built Power BI dashboards of ticket volume and resolution trends that gave Tier-2 and leadership visibility into recurring issues, while supporting Epic EHR, VMware, BitLocker, and Cisco Finesse.
Mathematics Instructor
May 2025 - July 2025- Taught 10+ students arithmetic, algebra, geometry, and statistics through one-on-one and small-group sessions on Zoom and Google Classroom.
- Built personalized lesson plans and tracked progress with regular assessments.
- Adapted my teaching to close individual learning gaps, consistently improving grades and academic confidence.
HERE ARE SOME OF MY FAVOURITE PROJECTS!
HealthNet - Segmented Clinical Network
A hospital-style network where every zone only talks to who it should.
- Segmented 6 VLANs behind least-privilege ACLs, passing 20/20 allow/deny tests (100% pass rate).
- Hardened access with SSH-only management, role-based AAA, port security, and a blackhole native VLAN, mapped to 8 NIST 800-53 controls.
- Diagnosed 4 injected faults (trunk, DHCP, ACL order, gateway), with a root-cause analysis for each.
Amazon Product Recommender Chatbot
Ask for a product in plain English and get answers from 500K+ listings.
- Built a context-aware RAG chatbot with LangChain, Groq LLM, and HuggingFace embeddings, reaching 90% retrieval accuracy.
- Stored vectors in Astra DB and shipped the whole pipeline containerized on Kubernetes (GCP).
- Monitored it live with Prometheus and Grafana dashboards for latency, throughput, and container health.
PLC Pump Controller - Three-Pump Batching Station
A pump station that keeps running when a pump fails.
- Automated a three-pump tank batching process in Rockwell RSLogix, passing 5/5 test scenarios.
- Built fail detection, lead/lag rotation, and latched alarms for automatic standby switchover in 100% of failure tests.
- Ported the ladder logic to Siemens TIA Portal and verified it in S7-PLCSIM, with 3/3 core functions behaving identically.
