Hello, I’m Darvin from Singapore

Fractional CTO for Startups

Delivering technology blueprints that are agile, scalable, and validation-friendly based on serverless cloud technologies.

Tell Me Your Idea*

*I will tell you whether it is feasible and how to test and validate it quickly so you do not waste much money.

A brief introduction

What Role Do I Fill

I specialise in crafting early prototypes using cutting-edge technology stacks to validate ideas for fledgling startups, often before they have a product or funding.

Much like how an architect drafts a blueprint before a contractor builds a house, a solution architect creates a technology blueprint independently before involving a third-party agency to bring your technology to life. This approach ensures a flexible relationship between architecture and development, allowing you to choose the best development team without being tied down prematurely.

What I Can Help With

Solution Architecture

An independent technological blueprint on which to develop your idea. This includes infrastructure, applications, databases, and various other things.

Validation Scoping

Build just enough for your validation to keep costs low. Capture the correct data points to prove that your idea works.

Agency Vetting

Communicate with the development agency as your subject matter expert to ensure they can deliver on their promises.

Entity Creation

Set up your entity in one of the trusted jurisdictions for startups – Singapore. As an accredited director, I can help navigate the requirements in setting one up.

What I Cannot Help With

I am NOT your cheap alternative developer. I will not build what you had in your mind as an MVP by myself with your shoestring budget. I aim to reshape the MVP to fit your budget so you can do market validation as soon as possible.

Engagement Phases

1. Discovery

Discovery calls with your various stakeholders to set the stage for the rest of the engagement. This is usually done across a few calls over a couple of weeks.

2. Scoping

Proposed action plan for your particular startup. This includes defining your hypothesis, identifying relevant metrics, and determining how best to validate it.

3. Architecture

Creation of technical architecture documents to support your validation effort. This includes infrastructure, applications, databases, and more.

4. Development

Assess and pick a suitable development agency that has a good track record. Act on your behalf as your subject matter expert.

5. Validation

Launch a prototype to start your validation process. Monitor metrics closely and implement changes in the hypothesis if necessary.

6. Maintenance

Ongoing maintenance for the whole system for as long as the validation phase is running. This includes bug fixing, system scaling up/down, etc.

Deliverables

You can bring these documents to any development agency and have them built.

Architecture Diagram

Your infrastructure blueprint is usually based on AWS serverless technology, which minimizes your running and maintenance costs while you validate your value propositions.

Data Modelling

This is a blueprint for how you should set up your databases. For agility, this will usually be based on a NoSQL database.

Functions Documentation

List of functions, their input and output, triggers, schedules, logic, and other relevant information necessary to create your prototype.

API Spec

API documentation on what endpoints are available for your front end (or customer) to invoke.

What It Will Cost You

Every project is unique, and so is the related fee structure. For most projects, the cost will comprise a combination of cash and equity. Every phase is designed to have an independent deliverable, so there is no lock-in, and you can choose to stop the engagement anytime.
