Raj Reddy — Software Engineer

Software engineer. Photographer. Curious mind.

About

I'm a software engineer at L3Harris Technologies, working on embedded signal processing systems and data infrastructure. I graduated from the University of Utah in May 2025 with a B.S. in Computer Science.

My interests span embedded systems, machine learning, and full-stack development. I enjoy building things that solve real problems — whether that's optimizing signal processing pipelines, training transformer models, or crafting interactive web applications.

Outside of work, I chase light with a camera, read, play soccer, and practice guitar.

Telesense

Multimodal Behavioral Analysis for Telehealth

Over video, clinicians lose many of the nonverbal cues they rely on — facial expression, tone of voice, pauses, how a patient's affect shifts mid-conversation. Telesense takes a recorded session and returns timestamped flags for moments that may need follow-up, alongside an emotion timeline, protective factors the patient mentioned, and intake topics that were never covered.

Research prototype

Research prototype. It does not diagnose, screen for, or assess risk of any condition, and its output must not be used to make clinical decisions. The public demo runs an uncalibrated pretrained pipeline — not a trained Telesense checkpoint, and not a diagnostic classifier.

Jogo Bonito

Cross-Era Football Simulator

An interactive football simulator that matches teams from different eras — 2023 Manchester City against 2016 Real Madrid. Explore historical squads, pick starting lineups and tactics, replay simulated matches, and compare outcomes across thousands of simulations.

Meridian

Sensor-stream alignment and deterministic replay

Aligns noisy sensor streams using bounded buffers, timestamp watermarks and scalar Kalman filtering. Durable event storage, deterministic replay, a WebSocket operations console and synthetic instrument monitoring.

Measured

Replayed 900 public sensor records with bit-identical output; browser message-arrival p99 of 6.187 ms. 14 tests pass.

Local implementation — deployment and the finished demo recording are still outstanding.

Source code

Relay

Durable workflow execution

Runs ordered workflows with idempotent admission, worker leases, fencing, retries, dead letters and replay. Internal effects commit atomically with workflow state, and the console drives pause, rollout and recovery.

Measured

Reconciled 67,688 workflows and 203,064 internal effects across a one-hour fault campaign — zero lost workflows, zero duplicate effects. 20 tests pass.

Local runtime and recorded demo; the full hour-audit export and interactive hosting are unfinished.

Demo Source code

Tally

Auditable ledger and decision platform

A double-entry ledger with exact money arithmetic, transactional idempotency, immutable journal records and balance reconstruction. Adds versioned decision rules, reconciliation review, merchant enrichment and feed-health monitoring over synthetic financial data.

Measured

Replayed 1,003 journal events to identical balances; decision HTTP p99 of 14.386 ms over 400 requests at concurrency 16. 27 tests pass.

Local application and recorded demo; persistent interactive hosting is outstanding.

Demo Source code

Pulse

Voice inference gateway with cancellation and recovery

Connects speech recognition, language-model inference and speech synthesis through an authenticated WebSocket gateway — faster-whisper, SmolLM2 and Piper behind bounded admission, circuit breakers, fallback before audio starts, interruption handling, worker recovery and latency instrumentation.

Measured

First-audio p99 of 734.14 ms at concurrency 4 on local CPU (8-token output cap, 8 samples), with worker-kill recovery and stale audio rejected after interruption. 17 tests pass.

Local CPU inference and recorded demo; continuous microphone capture, hosted inference and GPU measurements are unfinished.

Demo Source code

Gatekeeper

Release verification and canary rollback

Combines flaky-test detection, CI failure clustering, Terraform-plan risk checks and signed artifact verification, then puts a real HTTP canary proxy in front of the rollout with fenced controls, rollback and crash recovery.

Measured

Caught 6/6 seeded risky infrastructure plans with zero false positives across 10 fixtures; two HTTP rollbacks, one promotion and controller-restart recovery. 31 tests pass.

Local system and recorded demo; GitHub App installation, live JUnit ingestion and persistent hosting are unfinished.
