Point of contact
01 — The Studio
A studio of one, deliberately.
I'm Karthik — a Senior Software Engineer who has spent the last decade building and scaling products across the MEAN and MEVN stacks, and more recently, multi-agent AI systems.
CodeDelights is where that experience goes to work for individuals, friends-of-friends and small businesses. Every engagement gets the same architecture discipline I bring to enterprise products — encryption where it matters, clean code, honest handover — without the agency overhead.
You talk directly to the person writing the code. Decisions happen in minutes, not meetings, and every quote is personal.

From idea to shipped, without drama.
STEP / 01
Consult
Tell me your idea over a call or message. No forms, no jargon — just what you want and why.
STEP / 02
Scope
I propose the simplest version that solves it, with a clear timeline and a fair, personal quote.
STEP / 03
Build
Short cycles with working previews along the way. You see progress, not promises.
STEP / 04
Support
Launch, handover and honest aftercare. Your product, your accounts, your code.
06 — Principles
Small studio. Big-league engineering.
Direct collaboration
One conversation from first idea to final handover — with the person actually writing the code.
Senior-grade craft
The same architecture discipline as enterprise work: encryption, testing, clean and documented handoff.
AI-accelerated delivery
Multi-agent workflows and AI-assisted development mean faster builds — savings passed on to you.
Sensible budgets
Built for friends, referrals and small businesses. Every quote is personal — and refreshingly reasonable.
