agent-relay - Letting AI Coding Assistants Work as a Team

Client: Open source (free for anyone to use)

Business Goal

Developers increasingly use AI assistants to write code, and each assistant has different strengths. agent-relay lets a developer stay in the one assistant they are already talking to and have it hand work to the others, such as a second opinion or a review, then report back clearly whether the work actually succeeded.

What Needed to Happen

  • ▸ Work with the four most common AI coding assistants through one simple, consistent command
  • ▸ Give a clear answer at the end of every task (done, partly done, blocked or failed) instead of guesswork
  • ▸ Let assistants use it on their own, without the developer copying text between windows
  • ▸ Pass a task to a different assistant when one runs out of capacity halfway through
  • ▸ Show progress live on a simple local dashboard, with nothing sent to the cloud
  • ▸ Install in one step, detecting which assistants are already on the computer

Delivery Challenges

  • - Telling a task that really succeeded from one that only appeared to finish
  • - Picking up an earlier conversation with an assistant without it stopping to ask questions
  • - Handing over the full picture (goal, files touched, unfinished changes) from one assistant to another
  • - Cleaning up after each task so nothing keeps running in the background
  • - Keeping everything working as each assistant's tools change over time

What We Delivered

  • - Wrapped each assistant in a small command that behaves the same way and returns the same kind of result
  • - Added a standard interface that lets assistants start, check, continue, hand over and stop tasks on their own
  • - Built a handover that packages the goal, touched files and unfinished work for the next assistant
  • - Added automatic fallback to another model when one hits its usage limit
  • - Built a local dashboard to watch tasks live and spot the ones that need attention
  • - Wrote plugins and instructions so each assistant learns how to delegate
  • - Published it as a free, open-source package with an installer, a health check and automated tests

Business Outcome

Released free for anyone to use (version 1.3.2, MIT licence) and working with four AI coding assistants. We use it every day to build FitSchool: one assistant plans and checks the work while others build parts of it in parallel.

DreamsToDestiny - Online Booking and Payments for a Coaching Business

Client: Ipsita

Business Goal

Give a coaching business a website where clients anywhere in the world can book a session, pay in their own currency and get their meeting link automatically, while the coach manages everything from one simple dashboard instead of chasing emails and payments by hand.

What Needed to Happen

  • ▸ Clients in any country can book a session, with times shown correctly in their own timezone
  • ▸ Indian clients pay in rupees and international clients in dollars, each through a payment method they trust
  • ▸ Sign-in by a one-time email link, with no passwords to remember
  • ▸ One dashboard for the coach to see bookings, set prices, look up clients and track earnings
  • ▸ A blog that helps the business get found on Google
  • ▸ Strong protection against hackers and automated attacks
  • ▸ A calm, celestial look that matches the brand on every screen

Delivery Challenges

  • - Two different payment providers, each confirming payments in its own way
  • - Getting session times exactly right across many timezones
  • - Keeping the site fast and affordable on low-cost hosting
  • - Blocking hacking attempts and spam without making the site slower for real clients
  • - Keeping the custom design consistent across every page

What We Delivered

  • - Built the booking flow so clients pick a time in their own timezone and get an instant confirmation
  • - Connected Instamojo for Indian payments and PayPal for international ones, with automatic confirmation of each payment
  • - Set up password-free sign-in by email link, and automatic logout after inactivity
  • - Linked Zoho Meetings so every booking gets its video call created automatically
  • - Built the coach's dashboard for bookings, pricing, clients and earnings
  • - Added protection that recognises common attack patterns and slows down suspicious traffic
  • - Built a blog with categories, set up for search engines
  • - Designed the celestial theme and applied it across the whole site
  • - Set up automatic deployments so updates go live safely

FitSchool - One App for Clients, Personal Trainers and Gyms

Client: PragmaCoreLabs (our own product)

Business Goal

Build one fitness platform that works for everyone involved: people who train, the personal trainers who coach them, and the gyms they belong to. Clients log workouts and meals on their phone, trainers follow their clients' progress, and gyms manage members and staff. The coaching advice has to be clear about why it suggests something, not a black box.

What Needed to Happen

  • ▸ One product that serves clients, personal trainers and gym owners, each with their own view
  • ▸ A phone app that keeps recording a workout even with no internet, and never loses a set
  • ▸ Coaching that adjusts a training plan based on what the person actually did, and explains why
  • ▸ Food suggestions that always respect a person's diet and allergies, and stay quiet when unsure
  • ▸ Online payments for trainers and gyms, while staying free for the people who train
  • ▸ Privacy controls that let people see, export or delete their data
  • ▸ A look and feel of its own, rather than another generic fitness app

Delivery Challenges

  • - Making sure a workout logged in a basement gym with no signal is saved safely and synced later
  • - Keeping automated coaching suggestions safe, so nothing changes in someone's plan without them agreeing
  • - Supporting people who train at a gym, people who train alone, and trainers who work independently, in one product
  • - Making sure every person only ever sees their own data, across hundreds of screens and actions
  • - Redesigning the whole phone app screen by screen without breaking anything people already use
  • - Testing the app quickly and reliably on every change

What We Delivered

  • - Built the website and back end as one system, plus separate phone apps for clients and trainers
  • - Built workout logging that saves on the phone first and syncs when the connection returns
  • - Built a coaching engine that proposes plan changes with a reason, which the person can accept or undo
  • - Labelled the food library for diets and allergens, and made the filter refuse anything it cannot confirm is safe
  • - Kept supplement information factual and neutral, with no medical claims
  • - Added online subscriptions and invoices, email notifications, error monitoring and privacy-friendly analytics
  • - Designed a new visual style shared by the website and the phone app, with an automatic check that keeps screens consistent
  • - Built an automated test suite, including security tests that run on every change
  • - Set up automatic builds and deployments to a test environment used before release

Business Outcome

FitSchool is in active development and running in a test environment ahead of launch. The core is in place: workout and meal logging, offline saving, coaching suggestions, payments and privacy controls. The client phone app is being redesigned first, with the trainer and gym parts following.

OFDC Kendu Leaf Purchaser Portal - Sale Results, Lots and Dues in Four Languages

Client: Kendu leaf purchasers of Odisha (built from inside the trade)

Business Goal

We trade in kendu leaf ourselves, so we know the daily pain: sale results and lot details arrive as long documents that are hard to search, and working out late payment interest or godown rent means doing sums by hand. The goal was one simple website where any purchaser, in their own language, can find what they need on their phone in seconds.

What Needed to Happen

  • ▸ Available in English, Hindi, Bengali and Odia, chosen on the first visit
  • ▸ Search and filter OFDC sale results, then view or download them as a PDF
  • ▸ See current fresh, pending and resale lots with practical filters
  • ▸ Calculate late payment interest and godown rent for any lot
  • ▸ Simple enough for people who rarely use websites, with nothing to learn
  • ▸ Works well on a phone in the field, with no account or sign-in needed
  • ▸ Runs reliably on a small, low-cost server

Delivery Challenges

  • - Turning long documents published on the official OFDC website into data people can search and filter
  • - Translating every screen into four languages, including Odia and Bengali scripts
  • - Getting the interest and rent calculations exactly right, since purchasers act on them
  • - PDF downloads were slow and could fail when many people downloaded at once
  • - Filtering on a small phone screen needed a different design from the desktop one
  • - Keeping the site fast on slower mobile connections and a small server

What We Delivered

  • - Set up automatic collection of the sale results and lot lists OFDC publishes on its official website, so the portal stays up to date without manual copying
  • - Built a website with three clear choices on the home page - sale results, lot list and calculator
  • - Added a language picker on first visit and translated the whole site into four languages
  • - Built a calculator for late payment interest and godown rent for any lot
  • - Saved finished PDFs so repeat downloads are near-instant instead of rebuilt each time
  • - Designed a phone-first filter panel with large, touch-friendly controls
  • - Made the filters smart, so only valid choices are offered
  • - Put the site behind a secure setup with automatic HTTPS and attack protection

Business Outcome

Kendu leaf purchasers can now check sale results, browse lots and work out what they owe, on their own phone and in their own language, without waiting on anyone. It came from our own work in the trade, which is how we like to build: start from a real problem we understand first-hand.
