About me

Who I am?

Hi there! I'm Curtly. I'm a curious individual (good thing I'm not a cat) who hate doing the same task twice. My mantra is "Do it once and never have to do it again". As a result, I always try to solve problems in a future proof manner.

I had zero interest in the world of computer science until I entered the world of work. In my first post-college job, I was responsible for monitoring the KPIs of my organization. Rising to this challenge ultimately launched my software development career. You can read about how I solved my beautiful problem in the DataQuest article titled, “Not Enough Memory” — How Data Skills Ended an Excel Nightmare.

I spend most of my free time learning about any domain of knowledge; from history to natural science, to economics, to wars. I chose a career in Software Development since I can specialize in a career without giving up my interests in other domains of knowledge. A career in Software development allows me to develop the skills needed to explore the various domains of knowledge.

The biggest realization in my software development journey is that you always have to make trade-offs.

My projects

Below are the major projects I have been working on.

This project is an agriculture web app developed to assist farmers in determining the profitability of a Layer bird production system.

The application is an interactive dashboard overlaying a layer bird profitability model.

It allows farmers to adjust the cost and production parameters of the model to suit their requirements. The income and expenditure will recalculate based on cost and production parameter changes.

This project was built in flutter and hosted using firebase hosting.

A client reached out to me for assistance in creating a business plan for a Layer Bird Production Agribusiness.

After completing the project, I decided to combine my programming skill with my agricultural knowledge. This resulted in a Layer Bird Profitability Model to assist more farmers.

This project was initial built in excel for the client, then converted into a web app for the public.

My favorite part of the project was rebuilding the model in dart.

The trickiest part of the project was figuring out how to leverage the provider package to rebuild the UI when a parameter changes.

I encountered many challenges while working on this project. These were due to my inadequate understanding of constraints and the provider package. They were solved by reading the flutter documentation and researching flutter errors on stack overflow.

I'm satisfied that I was able to apply what I learned in my flutter experience so far to solve a problem in the agriculture sector.

I intend to continue improving this model by including more variables that influence the profit from a layer bird production system.

I have received positive feedback from my former boss. He is an agriculture expert and asked to build more models for a different agriculture production system.

As I continue to build more agriculture models, I would love to collaborate with various agriculture experts and companies to fine-tune the models.

This project has been wonderful learning opportunity. I learned to work with;

  • Getters and Setters
  • Provider Package
  • SyncFusion Package

The Guyana Performance Measurement Framework is intended to transform Volume 2 of the Budget Estimates to a web-based platform which will facilitate real-time entry of data on the national performance indicators being reported in the Estimate.

This project was build using Django and hosted on Heroku.

This website was built to allow for increased availability of information on the performance of central government agencies in Guyana. Government agencies will be able to access this platform to upload their respective indicator data.

Overall, this site will collect and report on national performance across all sectors.

This project was developed by constant communication with the client to understand what features and UX they wanted.

My favorite part of the project was designing the database schema.

The most challenging part of the project was implementing the authorization feature. They are two level of authorization; data providers and data verifiers.

Each government agency is responsible for reporting on and verifying their national performance indicators. National Performance indicator results are only displayed when the data verifier verifies the data recorded by the data provider. Every time the data provider records data, an email is sent to the responsible data verifier with a link to the page requesting their permission to verify the data.

I'm grateful that I was able to build a software to solve an issue of national importance.

Currently, the Ministry of Finance is entering the preliminary data needed before the government agencies can begin reporting on their national performance indicators.

This project has been a wonderful learning opportunity. I learned the following;

  • The importance of implementing adequate validation before data is made publicly available.
  • Django Signals
  • How to receive feedback from client and implement the necessary changes

The Livestock Information System app bridges the gap between farmers and extension officers by simplify the data collection and farm monitoring responsibility of Extension Officers.

This app also seeks to improve national agriculture production by enabling the Guyana Livestock Development Authority to provide farm specific training to farmers as a result of the data generated through this application.

This flutter app is still under development but is available for early access on the google play store.

The purpose of the Livestock Information System app is to demonstrate to Guyana Livestock Development Authority (GLDA) and by extension the Guyana's Ministry of Agriculture (MOA) that farmers can benefit from services tailored to their specific needs by using a custom-built app that monitors individual farm performance.

This app also seeks to demonstrate that the workflow of the extension officers can be reduced by the removal of redundant data collection.

This app was designed by feedback for an agriculture expert in GLDA and from my professional experience working in the agriculture sector.

My favorite part of this project was creating the service calls to create, read and update documents in firebase.

Key features of this application includes:

  • Can work online and offline
  • Farmer module: Register farmers, view farmer list and detail screens
  • Farm module: Register farms, view farm list and detail screens
  • Animal population survey: Records livestock population by species and growth stage.
  • Animal Disaster Survey: Records animal losses due to a natural disaster by species and growth stage.
  • Collect Farm GPS location
  • Collect Farm and Farmer profile picture
  • This application is currently a MVP. The Guyana Livestock Development Authority are registering farmers and farms using this app. They are over 500 farmers registered as of December 2021.

    My fulltime job and evening academic studies does not allow me the free time to continue working on this app. I am currently awaiting funding from the Guyana Livestock Development Authority to continue development of this app on a fulltime basis.

    This project has been a wonderful flutter and firebase learning opportunity. I learned the following;

    • The importance of coding defensively especially when make network calls.
    • Authentication with firebase auth
    • Accessing device camera and saving user provided image to Firebase storage
    • Accessing device gps location
    • Saving data to cloud firestore
    • Using streams to receive realtime updates form cloud firestore
    • Using Streams with Provider
    • Using gskinners MVC + S architecture to organize my code
