// hi, I'm Yash Chandak

Your idea, built right — the first time.

One engineer, the whole product: Django/DRF backends, Next.js and React frontends, and the Kubernetes, Terraform, and observability stack underneath — built to launch fast and stay reliable once real traffic shows up.

why it matters

Most products don't fail on the idea. They fail in the gaps between people building it.

A freelance frontend dev, a separate backend contractor, an agency managing both — each handoff is where scope gets lost and bugs get born. I build the whole thing myself: architecture, APIs, UI, and the infrastructure underneath, so there's no gap for anything to fall into.

about

The person building your system, not managing it.

No account managers, no relaying priorities through a project coordinator — when a decision needs to happen, it happens directly with the person writing the code.

Yash Chandak
2+ years building backend systems for platforms serving 1M+ daily users, across fintech, healthcare, media, and agri-tech — and the full stack around them: Next.js and React frontends, Kubernetes and infrastructure-as-code, and the observability and reliability practices that keep a system healthy after launch, not just on demo day. I got here by building the same product twice too many times with someone else owning half of it — now I own all of it, so nothing gets lost in translation.

Went freelance

Sole engineer on Enygma's product family — Django/DRF backends paired with Next.js frontends, architecture to production.

Now

Idea to production to scale

Full-stack and platform engineering for founders who want one person accountable for the whole product — including what keeps it running.

what I do

Engineering, end to end — idea to production.

Focused engagements, not open-ended retainers. One engineer, the whole stack, scoped outcomes.

01 · api
API Development & Integration
RESTful APIs built with Django REST Framework, following OpenAPI specs — designed to reduce integration bugs before your frontend team ever touches them.

Frontend & Product UI
Next.js and React interfaces wired directly to the backend that powers them — no handoff, no mismatch between what the API returns and what the UI expects.

Async & Queue Architecture
Background job pipelines with Celery, Kafka, and Redis that move slow work off the request path — built to cut latency, not just handle load.

who hires me

Two kinds of people reach out.

Non-technical founders
  • You have the product idea and the market insight, but no one to turn it into a real, working product — backend and frontend both.
  • You've been burned by an agency that shipped code nobody can maintain.
  • You need something you can hand to a future hire without a rewrite.
  • You want a straight answer about what's actually feasible before you commit budget.
Technical leads needing velocity
  • Your roadmap is moving faster than your hiring pipeline.
  • You need someone who ships across the stack, not another consultant who advises.
  • You don't have bandwidth to manage a full vendor relationship.
  • You need one focused piece of the product built well, not a whole team.

how it works

Idea to production to scale — every stage covered.

Seven stages, one engineer, no handoffs. No surprises about what happens next.

01

Discover

A working session to understand what you're actually trying to solve — the real constraints, not just the feature list. Scope and success criteria get defined here.

02

Strategy & architecture

System design and technology choices mapped out before a line of code ships — so expensive mistakes get caught on a whiteboard, not in production.

03

Design

Wireframes and user flows for the interface, so what gets built matches what your users actually need — not a guess made mid-development.

04

Build

Backend and frontend built in parallel by the same person, so the API and the UI that consumes it are never out of sync. Visibility along the way, not one reveal at the end.

05

QA & testing

Edge cases, error states, and load behavior checked before your users find them — automated tests where they matter, manual review everywhere else.

06

Launch

Deployed to production with monitoring and CI/CD already in place — launch day is a non-event, not a fire drill.

07

Support & scale

A defined post-launch support window, then ongoing work as real usage reveals what needs to scale next — the relationship doesn't end at deploy.

the guarantee

Every project ships with 30 days of support included.

Not a marketing line — an actual commitment, the same way any serious engineering partner should back their work.

Free bug fixes for 30 days

Anything that breaks that was part of the agreed scope gets fixed at no extra cost — no invoice for cleaning up my own work.

Direct access, not a ticket queue

You reach me directly — no support tiers, no "your request has been escalated" emails.

Scope agreed before work starts

Clear deliverables and pricing up front — no surprise invoices mid-project.

Real engagements, real outcomes.
