Available for work

Harshal Jagtap

Freelance engineer. AI automations, 3D applications, and internal tools.

Services

Three things I do well.

  • 01

    AI Automations

    I make automation workflows, and use AI when necessary to reduce the time taken to complete it by about 80%. Integrating dashboards so human interference where needed, can be implemented, and overall increase your daily work efficiency.

    • Workflow automation
    • LLM integration
    • RAG and knowledge assistants
    • Document processing
    • Agentic pipelines
    • API orchestration

    What you get

    • A working pipeline in your own infrastructure, not a demo
    • Your own VPS which runs only your services so that your data stays with you only
    • Your own private database to store your data, data never leaves you

    Typical engagement

    Typically 3–4 weeks. Fixed scope, one process at a time.

  • 02

    3D Applications

    I build 3D that runs in a browser, mobile devices, or your computers. Product configurators, viewers that load fast on a phone, and real-time data scenes. Performance is part of the brief, not something checked at the end.

    • Unity 3D
    • WebGL and three.js
    • React Three Fiber
    • Product configurators
    • Interactive 3D viewers
    • Real-time data visualisation
    • Asset and draw-call optimisation

    What you get

    • A viewer or configurator that holds 60fps on mid-range hardware
    • Custom 3d models
    • Animations that improve user experience and feel polished and premium

    Typical engagement

    Typically 4–6 weeks. Longer based on the number of 3D assets required

  • 03

    Business Solutions

    I replace the spreadsheet that four people edit at once. Internal tools, dashboards that read from the systems you already run, and web apps for processes currently living in email threads. The goal is fewer manual steps, not more software.

    • Internal tools
    • Operational dashboards
    • CRM and ops integrations
    • Process digitisation
    • Custom web apps
    • Reporting

    What you get

    • A deployed tool with authentication and role-based access
    • Integrations with the CRM, billing or ops systems you already use
    • Documentation written for the people using it, not for developers
    • Thirty days of fixes after launch

    Typical engagement

    Typically 4–10 weeks, or a monthly retainer when the work is continuous.

Process

How a project runs.

  1. 01

    Call

    Thirty minutes. You describe the problem, I tell you whether I am the right person for it. No deck.

  2. 02

    Scope

    I write down what I will build, what it costs and when it lands. Fixed price wherever the scope allows one.

  3. 03

    Build

    Weekly demos against a staging URL. You see the thing working rather than a status report.

  4. 04

    Handover

    Code, documentation and a walkthrough. You own all of it. I stay reachable for fixes.

About

Who you would be working with.

I am Harshal Jagtap. I have been building solutions for small, mid-large scale businesses for 2 years, most of it as the only engineer on the project. That means I write the code, run the deployment, and talk to the people who use the thing.

I take a small number of clients at a time so the work gets proper attention. If a project is not a fit, I will say so early and point you at someone better placed.

Tools

TypeScript, React, Next.js, Node, Python, PostgreSQL, three.js, React Three Fiber, Blender, OpenAI and Anthropic APIs, LangGraph, pgvector, Docker, Vercel, AWS, Playwright

Contact

Tell me what you are trying to fix.

The more concrete the problem, the faster I can tell you whether I can help and what it would cost.

I reply to everything within one working day.
