Kochi / remote · Open to roles
Harigovind Valsakumar
I'm a full-stack engineer in Kochi. Seven years at Gadgeon, mostly Angular, .NET Core and Postgres — healthcare, fleet, shipping. Since 2023 I've also been on a workflow product. I make iOS apps, and I run a home server they talk to.
A lot of the job is backends, databases, and the pipeline that deploys them. After hours I ship apps — Inventory QR is on the App Store, Kiln is on TestFlight, Beam is coming — and keep a box at home running media, downloads, and a GPU for image work.
2023 — Now
Workflow platform
A workflow product — React, Spring Boot and Flowable for the processes, Keycloak for login. Not Gadgeon.
2021 — 2023
Healthcare & shipping systems
Gadgeon. Inventory and logistics for healthcare and shipping. Angular on the front, .NET Core and Postgres behind it, hooked up to carrier APIs.
2019 — 2021
Fleet management & IoT
Gadgeon. I started on a fleet product. New device protocols, GPS coming in, .NET Core APIs on Kubernetes.
Apps
I built these.
TestFlight
Kiln
A podcast player that transcribes on the iPhone. You can search the words, not just the episode title. No account, and the transcript is free.
SwiftUI · On-device speech · CloudKit
In development
Beam
A Plex client for Apple TV, iPhone, iPad and Mac. Sonarr, Radarr and the rest of that stack live in the same place you browse.
SwiftUI · tvOS · Plex
Other work.
Workflow Automation Platform
A workflow product: React on the front, Spring Boot and Flowable running the processes, Keycloak for login. Separate from Gadgeon.
React · Spring Boot · Flowable · Keycloak
Healthcare Inventory & Shipping
Gadgeon. Inventory and shipping for healthcare. Angular and .NET Core on Postgres, talking to carrier APIs so stock and shipments stay in step.
Angular · .NET Core · PostgreSQL · REST
Fleet Management Platform
Gadgeon. A fleet platform that was already in production. I added new IoT protocols and GPS ingest, and put the .NET Core APIs on Kubernetes so we could ship without taking it down.
.NET Core · Kubernetes · Helm · CI/CD
Also built
From earlier.
App
Dispatch
Drive a Mac's Xcode from your phone: build, install, ship to App Store Connect. The
compiling stays on the Mac.
App
Diffuse
iPhone and Mac remote for a Stable Diffusion box. You type the prompt here; the weights
stay on the GPU at home.
ML / AI
News Originality, Bias & Accuracy Detector
Paste in a news article; it scores originality, bias and accuracy. Naive Bayes, trained
on 2016 US election coverage.
ML / AI
Superhero Character Predictor
Guesses which superhero is in a photo. CNN with Keras, trained on a set I labelled.
ML / AI
Credit Card Fraud Detection
Spotting fraud on a credit-card dataset that's almost all legitimate. SMOTE to even the
classes, scored on precision-recall.
ML / AI
Generate TV Scripts
An RNN that writes Simpsons dialogue. TensorFlow, trained on episode scripts.
Graphics
Fractal
Barnsley fern and chaos-game fractals, drawn with matplotlib and pygame.
