Current mission

Platform engineering, end to end.

Full-stack developer and DevOps engineer at Adroitx Limited (UK), working remotely from India. I design and operate the layers most people never see — networks, virtualization, CI/CD, and self-hosted services — then build the products that run on top of them. The homelab below isn't a toy; it's where I prove infrastructure decisions before they reach production.

Featured projects

Things I've built & shipped.

Public work and products I run. Deeper case studies (problem → architecture → lessons) are being written for each.

Vastavik

Media provenance & deepfake-detection platform
Commercial platform

An end-to-end media-authenticity platform — a multi-layer, fail-safe detection system across image, video and audio, with on-chain ownership, native mobile + web apps, and a business-verification (KYB) track. I led the ML, backend, computer-vision and blockchain work.

Detection engine
A multi-model detection ensemble spanning image, video and audio, with continual learning to keep pace with new generators.
Backend · Node/TS
Verification API, asynchronous job workers, object storage, payments and role-based access control.
CV forensics · FastAPI
Original-vs-edit forensic comparison across media, producing visual evidence for reviewers.
Blockchain · Go
On-chain media ownership — register, verify and transfer — on Hyperledger Fabric.
Clients
Native iOS (SwiftUI) and Android apps: capture, verify-with-original, and review flows.
Web · React/TS
Admin panel, creator portal and public verification sites over a Node BFF.
KYB track · NestJS
A separate business-and-website verification track with issued badges, embeddable proof and per-site billing.

fetch_pages

Open-source Flutter/Dart package · pub.dev
Published

A Flutter package that fetches JSON pages from a server for use with json_dynamic_widget — letting apps render server-driven UI without shipping a new build. Published on pub.dev with a clean, documented API.

Infrastructure lab

Kronos-Nexus — a homelab that behaves like production.

A segmented, self-hosted platform: a Proxmox host running the workloads, an OpenWRT router on a Raspberry Pi 4 enforcing VLAN isolation and firewalling, WireGuard for remote access, and a stack of services behind a TLS reverse proxy. Hover a node to see its role.

Stack

  • Proxmox
  • OpenWRT
  • Kubernetes
  • Docker
  • WireGuard
  • Nginx
  • Pi-hole
  • Unbound
  • Nextcloud
  • Prometheus
  • Grafana
  • Cloudflare
  • Let's Encrypt

Principles

  • VLAN isolation by trust zone
  • Least-privilege firewalling
  • TLS everywhere, one proxy
  • Reproducible, documented config
Production systems

Services I run in the open.

Public-facing endpoints served from the platform, behind the TLS proxy.
