Systems that keep working
when the internet doesn't.

Reddy Balaji Madha
status: building · Fremont, CA

I'm a backend software developer focused on production APIs, edge AI, and healthcare data systems. At Atian.ai I architect end-to-end systems in Java/Spring Boot and Python/FastAPI — NEMSIS 3.5.1 SOAP pipelines, AI-assisted patient care report generation, offline AI deployed on ARM64 devices inside ambulances, Snowflake-backed operations dashboards, and real-time Elasticsearch infrastructure.

Before this I spent two and a half years at Tata Consultancy Services doing automation and infrastructure reliability work — the foundation for how I build now: self-healing services, offline-first design, and test suites that don't need live dependencies. Currently pursuing an M.S. in Computer Science at Jessup University.

What I work with.

The tools behind the systems — backend first, with a deep edge-AI and healthcare-standards streak.

Backend Engineering

Production APIs and microservices — REST, SOAP, async workflows, schema validation, JWT auth, and XML/JAXB pipelines that survive vendor quirks.

Java · Spring BootPython · FastAPIaiohttp / asyncioREST + SOAPJWTXML / JAXB

Edge AI & IoT

AI that runs where the cloud can't reach — quantized models on ARM64 routers, cross-compiled containers.

Healthcare & Clinical AI

The unglamorous standards that make medical data move.

Browser Automation & Reverse Engineering

Production-scale automation against systems that were never meant to be automated — undocumented protocols, legacy UIs, safety-gated write paths.

Where I've worked.

Atian.ai (HealthyVibes.ai)

Dec 2024 — present · remote
Software Developer

Edge AI inference platform — ARM64 · Whisper.cpp · MedGemma · YOLOv8

  • Deployed edge AI on Ericsson R1900 (ARM64, 4 GB RAM) — Whisper.cpp at 14 s per 30 s of audio, YOLOv8 at 750 ms via ONNX Runtime
  • Built the automated encounter pipeline: YOLO triggers start/stop, Whisper transcribes, MedGemma 4B generates SOAP notes and PCR reports across a 17-task NLP pipeline
  • Cross-compiled Docker containers for ARM64 with buildx/QEMU; stress-tested 1,015 transcriptions at 103/hour with zero crashes

EMS intelligence analytics — Snowflake · FastAPI

  • Built a multi-tenant analytics platform for live ambulance districts — response times, dispatch lags, fleet GPS, billing revenue, AI documentation scoring
  • Designed the Snowpipe ingestion pipeline powering real-time KPI dashboards across operations, clinical intelligence, and revenue

NEMSIS 3.5.1 AI-powered submission pipeline — Java · Spring Boot · GPT

  • Built the end-to-end NEMSIS 3.5.1 XML pipeline: ASR → GPT PCR extraction → ICD-10/RxNorm/SNOMED mapping → XSD-compliant SOAP submission to state and vendor endpoints
  • Reduced vendor rejection rate via dynamic empty-section suppression and two-pass prompt engineering; deployed on Kubernetes (3-replica)

Clinical audit, QR handoff & infrastructure

  • Python audit pipeline with Sentence Transformers for confidence-scored consistency checks between EMS transcripts and clinical reports
  • QR-based JWT clinical handoff — zero-login ED patient access with 8-hour token expiry and patient-scoped security
  • Diagnosed Cassandra quorum loss and Kubernetes pod networking failures on AWS EKS; managed HL7 v2/FHIR ingestion services

Tata Consultancy Services

Feb 2020 — Aug 2022 · Bangalore, India
System Administrator — Automation & Infrastructure

Automation & tooling

  • Designed internal automation tools in Python, Bash, and PowerShell to eliminate recurring manual work and streamline operational workflows
  • Developed SQL-based diagnostic scripts to investigate production incidents and help application teams restore service faster

Infrastructure & reliability

  • Built monitoring and health-check scripts across Linux, Windows, and macOS for proactive detection of reliability issues
  • Worked production incidents with app teams — log analysis, network diagnostics, container-level troubleshooting

Notes from the rabbit hole.

Experiments, investigations, and what I learn while testing new technology.

Cropped YouTube Music page for Malia showing songs with hundreds of thousands of plays
July 2026 · AI, music & transparency

Can You Tell When a Song Is AI-Generated?

A random autoplay session led me to test how convincingly AI can imitate commercial music, and what listeners are told about it.
