Who I Help

Small businesses and startup founders who want software built around their needs.

Small Businesses

Stuck between spreadsheets and expensive platforms that don’t quite fit.

Startups

Need an MVP that won’t collapse at scale.

Agencies

Need a senior engineer to ship complex features fast.

Sound familiar?

What I Build

Purpose-built software that matches how your business actually runs.

Custom Web Apps & Internal Tools

For small businesses

When your business has real-world exceptions, "all-in-one" software often becomes a costly workaround machine. I build simple, tailored systems that match how you actually operate — and integrate with the tools you already use when it makes sense.

This can be one app, or a few connected pieces (depending on what's simplest).

Common solutions:

  • Custom web apps tailored to how your business runs
  • Internal tools to replace spreadsheets and bloated off-the-shelf platforms
  • Customer-facing portals (for clients, members, partners, etc.)
  • Automation + integrations so your tools stay in sync and work happens automatically

MVPs That Are Performant and Production-Ready

For startup founders

If you want an MVP that's a real product — not a demo you'll rebuild later — I can help you ship quickly without cutting the corners that create painful rewrites.

What you get:

  • Clean architecture and foundation that supports future iterations
  • Performance and scalability built in from the start
  • Real auth + roles: the basics done right from day one
  • Logging/monitoring so issues are debuggable

AI Features (Chatbots + Agentic Workflows)

Practical AI that fits your process

If AI can remove repetitive work or create a better customer experience, I can build it into your product — in a practical, controlled way.

Examples:

  • Custom chatbots trained on your business content (policies, services, FAQs, internal docs)
  • Support and intake assistants that ask the right questions and create structured records
  • Agentic workflows that take actions across your tools (e.g., update CRM, schedule follow-ups, generate summaries, route requests)

How It Works

A straightforward process that keeps you in control while moving fast.

01

Project Start & Plan

1–3 days

We quickly align on the high-level plan so the build goes fast and stays on track:

  • What you're trying to accomplish (the workflows, who it's for, and what "done" looks like)
  • The data + system shape (what needs to be stored, what talks to what, integrations, and what’s in/out of scope)
  • Delivery + success metrics (timeline, milestones, budget/tech constraints)

Deliverable: A short, clear plan. No over-engineering, just enough structure to move forward with confidence.

02

Build in Short Cycles

1–2 week cycles

  • Every iteration, you'll see real progress — what's been built and how it works
  • You'll give feedback (what you like, what to change, what's missing)
  • I'll adjust as needed based on your input
  • You stay in control as it takes shape
03

Go Live + Support

Ready for real-world use

  • Launch it for customers
  • Clear documentation for future maintenance
  • Set up monitoring and alerts as needed
  • Optional ongoing support

Tech Stack

I'm flexible, but I commonly deliver with:

Frontend

React / Next.js

Backend

Node.js / Next.js

Database

Postgres

Infrastructure

Vercel, DigitalOcean, Supabase, Azure, GCP

APIs

REST / GraphQL

About

Hi! I'm Elena Korotkina. I bring years of experience as a senior full-stack engineer, product and project manager, and startup founder. I've designed, built, and shipped production systems—big and small—end-to-end: frontend, backend, databases, integrations, and cloud deployment. I've tackled ugly performance bottlenecks and complex integrations, and I've loved collaborative problem-solving that turns uncertainty into clarity—aligning folks, exploring options, and shipping solutions everyone's proud of.

My approach combines the speed of modern AI tools with the depth that comes from years of building products and solving real problems in production. The result is software that works reliably from day one.

Excited to be part of your journey!
