Fullstack Web Developer

Hi guys I just want to share my web app ArvFit. 3 weeks ago, I shared the demo version and now the official version is out!

ArvFit - a Gym Management System Saas tailored for small to medium gyms who wants to know their numbers and wants to scale-up later on.

I built this app because I noticed that in our area, local gyms still writes manually and owners struggle to track memberships and check-ins.

My First Fullstack Web App. Check this out!!!

Day 154 of Programming.

App:
============= ArvFit MVP ============

Notes: The UI/UX may not be on to your liking as it is my first time using React and learning frontend as a whole. This is still an MVP so, I can slowly learning and upgrade this one.

WHAT ???
Details:
- A Multi-tenant Gym Management System Software as a Service
- Can add admins to handle most of the operations
- Operations include:
-> adding, updating, renewing, and deleting members
-> recording sessions (member and single sessions)
-> recording payments (membership, renewal, session payment)
-> recording filtered logs by date and category

Features:
- Light & Dark Theme
- Dashboard with Recharts

TECH STACK:
Frontend:
Framework -> React-Vite Typescript
Styling -> TailwindCSS
Packages -> npm

Backend:
Language -> Python-FastAPI
Auth -> OAuth2 JWT
Database -> PostgreSQL-SQLAlchemy
Migration -> Alembic

Status: not yet deployed
-> Can you give me suggestions and tips in deployment mga idol. Help a beginner out here.

WHY ???
- My hobby is to run and I go to gym sometimes for strength training. I noticed that the local gyms in our area still writes by hand using log books. That was when an idea came to light. "Why not make an app for it? I know there is already a ton of apps/systems in the web but why not try with my own version.

- I am still a beginner and thus still a lot of things to learn. You can give feedbacks so that I can learn mga idols. I learn by building and build while I learn. Being a solo dev is really hard, doing all of the processes alone but we have to push through. With that being said, for those solo dev and a beginner like me, you can connect with me and maybe we can learn and build together.

Day 87 of learning Programming:

Currently working on: Automated Email API for Portfolio Website

Updates:
- deployed the dockerized automated email api on render
- encountered SMTP network error when my website used the api
--- it works on local dev but it turns out some deployment environments block outbound SMTP traffic
Common blockers:
Docker container with no outbound internet
VPS firewall
Cloud provider SMTP blocking (very common)

Solutions:
- will try to change smtp port from 465 to 587
- if not resolve, will use an email api (Sendgrid)
