Authentic Track Record

The 8-Year Tinkerer's Journey

2018 — The 6th Grade Awakening

Sony Laptop Home Server

Started coding in BlueJ (Java) and PHP. Turned an old Sony laptop into a 24/7 home web server, learning port forwarding, NAT routing, and firewall troubleshooting the hard way.

2020–2022 — The Self-Hosting Battles

Webmin, BoxBilling & VPS

Dove into Linux control panels, debugged Russian BoxBilling language modules, moved to cloud VPS (Contabo), and mastered DNS record lifecycles.

2024–Present — Hansraj CS & SaaS

Enterprise Multi-Tenancy & Web3

Combining Hansraj College CS theory with modern cloud architectures (Coolify v4, Traefik, PostgreSQL 16) and decentralized Web3 primitives.

Featured Engineering Case Study

Tespil 4-Tier SaaS Engine

Hierarchical Multi-Tenancy with Data-Only BYOS

Designed a multi-tier SaaS platform supporting Vendor $\to$ Reseller $\to$ Customer hierarchies with dynamic database isolation, automated Traefik on-demand SSL, and an enterprise **Bring Your Own Server (BYOS)** privacy shield.

✓ Data-Only BYOS: Client VPS hosts PostgreSQL only; zero code leak
✓ Coolify v4 REST API: Automated domain, SSL & container orchestration
✓ AES-256 Tenant Field Encryption & Master Control-Plane Isolation
Locked chain: tespil.online (landing: 4-level + plans $29→$499) · status.tespil.online · beta.tespil.online · *.tespil.online + custom via Coolify

Future Vector

Web3 & Decentralized Primitives

Exploring self-sovereign identity, decentralized object storage (IPFS/Arweave), smart contract escrow workflows, and crypto-native micro-billing layers to merge Web2 SaaS with Web3 trustless execution.
