About SevyDevy
SevyDevy isn’t a startup idea imagined in a boardroom — it’s the platform I needed while building for myself. I’m Saket Bhatnagar, a solo developer who knew system design, interviews, and hiring struggles intimately, which is why every feature you see here started from my own pain points, not theory.
I went through the same loop as every engineer who dreams of designing scalable systems: abstract system design lessons, vague feedback, outdated resume advice, and platforms that only solved fragments of the journey. I wanted one place that:
When I couldn’t find that place, I built it — first for myself, then for every developer who values clarity over noise.
I built the tools I needed to practice system design, capture AI feedback, sharpen my resume, and rehearse interviews without pressure.
These features were battle-tested by me before they ever shipped.
SevyDevy began as my personal workspace. I use it daily, refine it constantly, and build every feature around the experience I wish I had during my most critical interviews.
Practice
System design prompts with real-world constraints, not code golf.
Feedback
AI reviews that explain trade-offs like a senior engineer would.
Resumes
Job-aligned advice that feels connected to actual expectations.
Interviews
Practice, review, improve, and repeat until confidence surfaces.
The AI doesn’t simply score answers; it walks through trade-offs, architecture decisions, and critiques the way a seasoned engineer would.
There are no templates. It’s all about thinking, scalability, constraints, and the decisions engineers face in production.
Every path maps to hiring outcomes — resumes, interviews, and the realities of real job postings.
No layers, no fluff. Every decision is intentional and grounded in how I actually use the product — every bug is personal.
Remove confusion from a developer’s growth journey, so you can understand system design deeply, walk into interviews with confidence, present skills clearly, and stop feeling lost or underprepared.
Build a world-class engineering platform from India that is used globally, trusted by developers, and respected by companies — elevating how engineers are trained and evaluated.
Indian engineers already power the world’s best teams. SevyDevy reflects that reality with Indian roots, global standards, affordability, and premium relatability.
The market is full of fragmented, costly solutions that serve marketing decks more than engineers. I needed a full suite under one roof, so I built SevyDevy and kept the price tied only to the infrastructure, AI compute, and servers required to keep it reliable — no investor fluff, just the tools I use daily.
Rather than paying for scattered coaching, mock interviews, and resume advice, SevyDevy bundles the entire system design to hiring workflow. I kept the pricing focused only on the servers and AI compute it takes to run this platform, not on inflated margins or investor expectations.
There’s no big org chart — just one developer, me. That means every feature is intentional, every bug is personal, and every improvement comes from real feedback. I use SevyDevy myself, so when it works for me, it works for you.
If the story resonates or you want to talk about a feature idea, send me a note. I’m genuinely hands-on with SevyDevy and love hearing from those who are grinding through system design like I do.
