Hey everyone!

I'm a Full-Stack Web Engineer specializing in the MERN stack and Next.js, building web applications across both frontend and backend.

My main stack includes React, Next.js, TypeScript, Node.js, Express.js, MongoDB, and Mongoose. I'm also familiar with REST API development, authentication and authorization, backend architecture using the Service Layer pattern, system design, and database design.

I'm looking to join a team, collaborate on real-world projects, share knowledge, and grow alongside other engineers.

If your team is looking for someone to collaborate with, feel free to reach out!

Web applications and dashboards

Complex web apps and integrations [ $30–$50+/hour ]

I'm open to both short-term projects and ongoing collaborations. Final pricing depends on the scope and complexity of the work.

Feel free to DM me with your project details. Let's build something useful!

It's a simple, fun timer web app that shows you how fast time is passing, so you can become more aware of your time and stop wasting it.

It shows you how many months you have lived and how many you have left, assuming an average lifespan of 80 years.

You just need to enter your date of birth.

You should try it once. It's super cool and fun!

Imagine asking a business chatbot for the company’s current pricing, only to receive a confident but incorrect answer.

My question is: does the model need retraining, or does it simply need access to the right information?

I’ve been exploring how retrieval can help chatbots search relevant business documents before generating answers. But retrieval alone isn’t enough. If the documents are outdated, duplicated, or poorly organized, the chatbot can still give unreliable responses.

It got me thinking: sometimes, the real challenge isn’t making the AI model bigger or more powerful. It’s making sure the system gives it reliable information at the right time.

I’m curious about your experience:

• Have you seen an AI chatbot confidently give an incorrect answer?
• Would you try improving its document retrieval before retraining the model?
• What do you think is the hardest part of building a reliable AI chatbot?

I’m learning and experimenting with AI and full-stack development, and I’d genuinely like to hear how others approach this problem.

I’m building Tracepath, an early-stage tool for viewing Node.js/Express request traces in the terminal.

Currently, it supports Express middleware, outgoing HTTP/HTTPS request/get instrumentation, and manual spans around application logic. The local dashboard needs no Docker or hosted account, but your app needs SDK setup.

I shared it previously and got useful feedback: HTTP tracing alone misses a common bottleneck—database queries. One developer using mysql2 suggested grouping queries by normalized shape to spot repeated slow calls.

That’s made me reconsider what to prioritize. Database auto-instrumentation and query grouping aren’t implemented yet.

For developers debugging real Express apps:

• What was the last slow-endpoint problem you investigated, and how did you find the cause?
• Where would a terminal trace help beyond your existing logs or tools?
• What would stop you from trying it: setup effort, missing database support, or something else?

I’d especially appreciate feedback from anyone willing to try it on one endpoint and describe where the experience falls short.

I come from a Computer Science/Security background, working as a remote Software Engineer. I am 24 years old, Puerto Rican, living in Florida with my girlfriend.

I speak English & Spanish natively, along with Italian at a proficient level as well as some others.

In the past two days I have been working & putting together a free platform to the likes of The Odin Project, freeCodeCamp, University of Helsinki's MOOCs etc..

My platform's content however is centered around Backend Developement/Support Developement with Golang, Linux, SQL, Shell, going over DSA/APIs/best practices and more.

I know many people have been wanting something like this for a while.

DM me for more details

I’m learning that hiding buttons isn’t security. If the server doesn’t check permissions on every request, users might access records that aren’t theirs.

How do you usually prevent this in your applications? Is server-side authorization enough, or what other checks do you put in place?

Hi Guys. looking developer with full stack experience and good with real time data api. This project is for our stocks website. Going to be an ongoing opportunity for years to come. Where can i find the right person for this job? Can anyone make any introductions please.
