Fractional CTO for SaaS
Hands-on Technical Partner

Product · Architecture · Infrastructure · AI

I've spent 24 years in technology and product, the last decade building software hands-on as an independent technical partner for SaaS companies in the US and UK. I work with founders and small teams who want one senior person to own the technology and think about the business alongside them, without the overhead of a full-time CTO.

What I do

Fractional CTO

Technical strategy, architecture decisions, hiring input, vendor and infrastructure choices, and pricing and product discussions: the standing technical judgment a SaaS business needs, a few days a week.

Hands-on development

I write the code myself. Full-stack work across Next.js, React, React Native, Node.js, and Python: new features, payments and billing, internal tools, APIs and integrations, marketing technology, analytics, and the unglamorous maintenance that keeps a product healthy.

AI in production

I've been building AI features for real users since 2023: a conversational practice chatbot, retrieval-based (RAG) lesson assistance, and automated translation pipelines, all running in production inside a paying product, not demos.

What working with me looks like

Over the last decade I've worked with US and UK clients (SaaS companies, design studios, and agencies), usually in long retainers, two or three clients at a time. The deepest of these engagements began in 2020: a US-based language-learning platform. What started as development work has grown into responsibility for most of the technical decisions the business makes. Today I look after everything technology touches: architecture, features, AI, marketing technology, ad attribution, analytics, internal tools, and infrastructure.

Most of my client relationships have lasted years, and I prefer it that way.

A builder, not only an advisor

I'm also a founder. I'm currently building Automette, a document automation platform for generating documents, PDFs, and images from templates through a UI and API. Before that, I founded and ran FinanceTrain.com, an education platform for finance professionals, for over thirteen years.

Running my own products keeps my advice honest. I feel the consequences of technical decisions the same way my clients do.

What clients say

Learn Kraft is my no. 1 recommendation for any web development work, globally!

I've been working with Manish for over a year now. We are an exclusive design house and had been working with many developers to execute our projects. That was a big challenge for us. Now all our projects are executed just by Learn Kraft. The team has expertise in every area of web development and they deliver really quick.

Background

I started in 2001 in financial e-learning, growing from content developer to running a development center. I then spent two years as Director of Solutions at a data analytics consultancy, leading BI implementations and pre-sales. Since 2015 I've worked independently. Along the way: an MBA in systems and finance, and a habit of ending up responsible for whatever sits between the business and the technology.

Work with me

If you're a SaaS founder who wants a senior technical partner, or you know someone who does, I'm at manish@learnkraft.com, or you can book a call. I work in long engagements and take on two or three clients at a time.
