Hire the Best ColdFusion Developers
in Brazil

It was the most important moment of my 13+ years of career. It was when I realized that there is always a trade-off in technology. You have to do something intentionally bad in order to succeed as a Small Medium Business in the Digital Transformation. And 70% fail because they insist on doing this very thing well. A while back, when I finally landed a job in a corporation, I was excited that I was going to use state-of-art technology. But, one of my first features immediately added some bugs. As I fixed those bugs, I introduced another, but also other bugs started to pop up caused by previous developers. In laymen terms, it is like a Rubik’s cube. As you carry on assembling the second face, you may accidentally mess up the first bit. It wasn’t like that when I started my career in technology in the civil service a long time ago. Yes, I was frustrated because we used old boring technology. But, we didn’t have to put out the fire all the time because that limited technology prevented us from getting in this position. Coincidence or not, the easiest way to solve the Rubik’s cube is putting constraints. If you move towards, you have to move backwards at some point. Fast forward to nowadays, some of my clients want to create highly customized User Experience. As the project starts to grow, hyper customization introduces more complexity. Then, you make a small change and get unexpected results. You didn't account for all the complex consequences. And this happens again and again, and you can’t avoid it. The software had become brittle. You start to miss deadlines or have to hire more developers to fix cracks faster, and eventually I get hired. That’s the time I have the hard talk: don’t bite more than you can chew, stop chasing the perfect User Experience (good User Interface is not a problem though) with a small team. If a BigTech didn’t have to hire thousands of engineers to provide that, they certainly wouldn’t. Anyway, User Experience is only noticed by B2C clients, and this is where Big Techs thrive. In B2B or internal tool software, who pays for the software won’t even use it. Hey, my name is João, I’m a software architect and developer, feel free to send me a message asking how I can make your business grow. What technologies do I work with? The simple ones: HTML, CSS, Bootstrap, Bash, XML, PostgreSQL, Apache Camel, Apache Knowledge Is Everything, Keycloak. If you need a hypercustomized solution, I can decently program in Java, Python and JavaScript, though. If you have any doubts, don’t hesitate to contact me.

Most data teams have infrastructure that looks good on paper but still can't answer basic business questions fast enough. I fix that end to end. With 7+ years in data engineering, I specialize in Snowflake, Databricks, and AWS building pipelines that actually run in production without breaking at 6am. Recent work includes: • CI/CD pipeline for a US healthcare client using Schemachange + Snowflake with automated DQ checks and deployment gating • Databricks-to-Snowflake migration of a 200-view mart package, rebuilt natively in Snowflake SQL • ML-powered matching service on FastAPI with pgvector semantic search and a LightGBM reranker • End-to-end RAG pipeline using Airflow, Pinecone, and OpenAI I work as an independent contractor no middleman, no overhead. I treat your problem as mine to solve, not a ticket to close. If your data is slow, unreliable, or not being used strategically, let's talk.

I am a software developer with 17 years of experience, using technologies such as: Delphi, PHP, Postgres, Firebird, GiT, SVN. I've also worked with Dataflex, Visual DataFlex and PowerBuilder, but in the last 10 years, I've been more focused on the technologies of Embarcadero Delphi (7, 10.x), in particular, development of API Rest application servers with technologies such as Datasnap and TMS Aurelius (ORM). Of these projects, 15 years of management were for projects in the management area public, in particular: Accounting, Tax, Legal (Attorneys). I also worked on parallel projects, in the areas of industry and business. Competence in managing the software development cycle, identification of need or scope, survey requirements, software architecture, diagram design streams(Bpmn), code, application testing and documentation technique. In recent years, I have been working especially with software integration using RestFull tecnology
