Software Development & Architecture · AI · BI & Analytics
From legacy to future: websites, apps, web systems and automations that make sense for your business, with artificial intelligence built in.
Every solution starts from the problem, not the technology. The stack comes later.
Your business card on the internet: corporate sites and lead-capture pages, fast and good-looking on any screen, with a contact form, WhatsApp and SEO. We also take care of domain, hosting and professional email.
A website presents your business; a web application works for it. Custom systems with registries, workflows, dashboards, business rules and access control, with an architecture that grows with you.
Android and iOS apps that talk to your systems, ready for the daily routine of teams and customers.
Code-based routines that remove manual work, and middleware that makes your systems talk to each other: ERP, e-commerce, invoicing, spreadsheets, WhatsApp, Instagram and Facebook integrated, plus AI agents for customer service.
Electronic document and content management (ECM) and portals and websites (CMS) with Alfresco Community: deployment, customization, integrations, archive migration and workflows, with AI to classify and search documents.
Data turned into decisions: building metrics and indicators, modeling, dashboards and analysis, computational optimization (routes, schedules, allocation) and geographic data, with AI to find what is out of sight.
Backup of your files with versions: you choose how many versions to keep, for how many days and how much space to contract, and you see what fits and what would be lost if the space shrinks. Windows installer and Linux package in development.
Centralized users and passwords, shared folders and access rules for small businesses: a network domain (Windows Server or Samba on Linux) with Windows and Linux workstations joined, and your internet domain (registro.br) pointed to your website and e-mail.
There is no single model for everything. We design a pipeline where each stage uses the right technique: classical computational intelligence where accuracy and auditability matter, generative AI where language matters.
Integration and ETL: Oracle, SQL Server, PostgreSQL/PostGIS, DBF, APIs, files and geographic data.
We gather scattered information and make it clean and reliable.
See a data demo →Machine learning and optimization: decision trees, regression, classification, metaheuristics.
Finds patterns, makes predictions and searches for the best route, schedule or allocation, with results you can audit.
See a route optimization demo →Language models (LLMs) grounded in your documents.
Reads, summarizes, answers questions and writes reports in natural language.
See a generative AI demo →XAI: LIME, SHAP, surrogate tree, permutation importance, Anchor. Scored by fidelity and faithfulness (research line of my master's degree).
Shows why the AI reached that answer and which explanation method is the most reliable for each model.
See an explainability demo →Orchestration in code: APIs, scheduled jobs, integrations.
The result becomes an alert, a report or a system update, with human oversight.
See an orchestration demo →Example: a document arrives as a PDF → generative AI extracts the data → the classical model estimates deadline or risk → explainability shows the factors → the system notifies the person in charge.
Besides custom projects, we are developing our own products for segments where we have experience. Want to follow along or test them first? Talk to us.
Automated accounting and financial routines, reconciliations and reports for accounting firms and small businesses.
Keep me posted →Laboratory management: sample registration, results, traceability and reports.
Keep me posted →Identification of materials and samples with labels and barcodes following international standards, with traceability.
Keep me posted →Experience from someone who has faced large systems, heavy data and old technology.
Mainframe, xBase/DBF databases, Oracle, SQL Server and PostgreSQL. We migrate, integrate and modernize without stopping operations.
Massive loads and high-performance routines with Oracle, Go and Linux shell, built for real volume.
Master's degree at DCC/UFMG on interpretability metrics: methods such as LIME, SHAP, surrogate trees, permutation importance and Anchor are evaluated by fidelity, faithfulness and other criteria, with a score that indicates the best method to explain each model.
Experience with centralized authentication and authorization (IAM), serving multiple systems through reusable services.
Leading projects, contracts and deployments of large-scale systems, including document management with Alfresco.
Monolith when simple is enough, microservices when they make sense. Technical decisions in service of your business.
Flexible, no red tape and no lock-in.
You bring the need, we define the scope together and deliver in visible stages. Ideal for a specific system, app or automation.
Ongoing evolution, support and new ideas, with no lock-in. You stay as long as it makes sense.
Every scenario is unique. Let's talk about yours and find the format that fits.
Support to get started: every engagement includes 1 hour of free remote assistance for the initial setup (AnyDesk or another free tool). Additional hours, up to 3, are billed on your next invoice. Ongoing support is contracted separately.
BIASW joins two ideas: BIA, for Business Intelligence & Analytics, and SW, for Software. And it has a third reading, the most important one: BIA is also my daughter's name.
I'm Helton, a software architect with years of experience in development, databases, BI and digital transformation. With a degree in Information Systems from PUC Minas and a master's in Computer Science from UFMG, I use AI as a daily partner to deliver with more speed, precision and quality.
Behind every project, the commitment is the same one I would have for her future: to build something solid, clear and lasting.
