How to eliminate overengineering without adding spaghetti code with the best programmer and thinker in Central America. Carlos Alonzo. I consider myself a problem solver, I always analyze any issue in the developing process, find the root cause of the problem and design a solution for it, during all my years of experience I had developed the natural ability of fast adaptation for any new project and the challenges that it might bring over to the table, the reason why I do not rest until reaching the highest level of quality, I am addicted to success. My areas of specialization are Laravel, React, and Vue by using these tools I had opened my road during all these years of experience making possible what looked to be impossible to materialize from the idea of my customers this is a clear example of that; Booking Spot for Players (PHP + Laravel + jQuery + React): consists of a customer being able to purchase N number of spots in a game. The payment was requested with Moneris API (accepting MasterCard, VISA credit/debit cards). In the provider panel, can offer their facilities or locations for hosting a game. Can create future games, delete or update them. just allow me a couple of minutes of your time to talk to you about my goals and experience. These are the goals that I always have in mind every time that a project or task is assigned to me, first of all, I make a list of the requirements to determine the desired range of the project, after that I Plan all the scopes based on the time required, by this point is necessary to take some time to think how to avoid and manage any problem or issue on the developing process, is necessary to keep a well-organized structure on the project itself and a fluent communication with my customer to be able to deliver progress on a regular basis and finally but not less important my final goal to accomplish success is Checking the results with the right tools making sure in that way the final product to be deliver is exactly what the customer wanted and with best quality ever. My experience has been and long road, full of learning opportunities and knowledge gains that have sharped and shaped into the kind of professional that I am right now, Specialized in business, commercial, Logistic (Reservations systems), financial systems (Financial report systems, Payment systems), shopping systems and Admin systems. (Corporate documents storage systems). Between less effort is invested in improving our skills less of a programmer we can be called Read it, learn it, apply it, read more, learn more and Evolve, never stop in the quest for excellence.

Senior Engineer with 17+ Years of Experience | Laravel · Vue · React · Next.js · Supabase · Inertia · Mysql · PostGreSQL | SaaS, Multi-tenant, AI & IoT Platforms I've been building web software since before "full-stack" was a job title. Seventeen years later, I'm leading senior engineering teams and guiding startups as a fractional CTO. If you are an early stage startup or a solo founder or an Enterprise, this is how I can help you: ➡️ Building your SaaS & Web Apps — Laravel, Vue.js, React, Next.js, Node.js, REST APIs, PostgreSQL/MySQL ➡️ E-Commerce & Marketplaces — Multi-vendor platforms, custom storefronts, Stripe/PayPal integrations ➡️ Legacy Rescue — Taking over broken Laravel/Vue codebases and making them something you're not embarrassed to show people ➡️ AI & Automation — LLM integrations, GPT-based features, workflow automation ➡️ IoT Platforms — Device networks, real-time pipelines, operational dashboards Some work I'm proud of: - I architected the Indiana First Steps platform for the US government — a HIPAA-compliant early intervention system with multi-agency data sharing and eligibility logic that had to be right, because the people depending on it couldn't afford for it not to be. - I was a Technical CEO for a US utility SaaS company, where I designed the backend infrastructure managing 10,000+ households daily. IoT device networks, real-time data processing, the works. That one taught me a lot about what "scale" actually means versus what people say it means in job posts. - I led frontend architecture for Rebel Walls, a global e-commerce brand that needed cinematic performance across markets. High-traffic, high-stakes, zero tolerance for slow. How I work: I've held CTO, Product Lead, and Scrum Master roles — so I've sat on both sides of the founder-engineer tension enough times to know where it usually goes wrong. My job is to close that gap: give you an honest read on what's feasible, tell you when a scope is going to bite you later, and ship code that the next developer won't curse me for. I also run Kinetik Dynamics, which means if your project suddenly needs to move fast, I have senior engineers I trust who work under my direct oversight. Not outsourced. Not farmed out. I'm still the one responsible. Stack I work in regularly: Laravel · Vue.js · React · Next.js · Python · TypeScript · Tailwind · PostgreSQL · MySQL · Redis · AWS · Docker · REST & GraphQL · Stripe · OpenAI API · Gemini API · Claude API · Supabase If the project matters to you, send me the details. I believe, I can help you out greatly.

I started programming as a kid and it’s been more than 20 years now. My first language was Pascal, then C/C++ and then I moved on to interpreted languages, like PHP or Python. My professional career in web programming began back in 2011: since then I have delivered dozens of web applications in PHP (Symfony, Laravel) and Python (Django), among others. I treat my experience as a responsibility: I know what works and what doesn’t and I can judge the consequences of many technological choices - that’s why I am always honest and realistic with my clients, offer my advice, and if necessary, try to dissuade them from solutions that might not work as they have envisioned. My main focus is on code quality and practicality. My ambition is to write reliable, fast, easy-to-modify code that can be written in a relatively short time. I always seek a balance between perfection and practicality in my coding (since the road to perfection is infinite and time until the deadline is not). I am a strong proponent of code that can be documented only by its contents and unit tests. I am also a fast learner. I don’t treat any framework as anything more than another tool made for convenience. When the need arises, I can learn most programming libraries and frameworks on the spot (as long as it's in a programming language I know). I always enjoy a new challenge! My technical expertise covers: - Databases: PostgreSQL, MySQL, SQLite, Oracle, MongoDB - VCS: Git, SVN, Mercurial - Issue trackers: Jira, Asana, Redmine, Trello, Harvest - Hosting: AWS, Linode, CPANEL/WHM, GoDaddy, Github Pages - Server OSes and tools: GNU/Linux (experience with most of popular distributions), Kubernetes (minikube, EKS), AWS Lambda, Apache2, Nginx (php-fpm and uwsgi), Ansible - Code quality: PHPUnit, Python unittest (also in conjunction with Django), pytest - Search: ElasticSearch, Solr - REST API development: experience in Django (REST Framework), FastAPI, Symfony, Laravel, and Node.js - 3D graphics programming: OpenGL in JS WebGL, C/C++ OpenGL libraries and PyOpenGL+pygame in Python - Others: Websockets (experience with implementation in Django, FastApi, Python in Lambda, Laravel and Ratchet). - Payment gateway integration: Paypal, Stripe, Braintree, Przelewy24 My technology stack: Backend: - PHP: Laravel, Symfony - Python: Django, FastApi - JS: Node.js Frontend: HTML, JavaScript, TypeScript, React, Angular.io and Angular.js, Vue.js, jQuery, Three.js, CSS, SASS, LESS, Tailwind, Bootstrap, AdminLTE Mobile technologies: React Native If you are looking for a reliable business partner, I have good news for you: I work with Polcode Software House - one of the top rated agencies on Upwork, located in Poland (EU).
