As software developers we strive to deliver not only well-written code, but code that delivers real value to every client. Have not just a good web application in production, but also improve your software processes and quality assurance.
Engineering applied to integrations: versioned contracts, idempotency patterns, and observability from the first sprint — ready for regulated environments and high load.
API-first
contract design
4 phases
from diagnosis to support
Unite systems and data with clear architecture, making integrations accessible, useful and lower-risk for the business.
A world where resilient, well-governed integrations expand opportunity, reduce technical risk and sustain continuous operation.
Remote-first, engineering with purpose. Our greatest product is people: we value talent, transparency and growth.
Inspired by practices and public statements from companies such as Google, Ericsson and Meta.
We identify the best model for your context: team reinforcement, full project, or capacity building.
We identify the best team to help you achieve your goals.
Your team may be overloaded with demands, affecting delivery dates. The best approach is to divide and conquer. Let your team focus on specific objectives and call us to help with new features, extensions, maintenance, and more.
Ideal for companies with an established development team.
Our team is responsible for the full development of your project.
We provide cost estimates and delivery forecasts, then work on implementation using agile best practices. Scope is variable and we frequently reassess what should be built, so you get the software you really need at the end of the project.
Ideal for companies without an in-house development team available.
We help you better understand what you need to achieve your goals.
We bring you a team of skilled professionals to help develop your projects. We also offer programming courses so you can grow in other languages and technologies.
Ideal for companies or individuals who want to develop skills in other languages.
Flexibility for your context: hourly rate, fixed price, retainer, shared success, and special cases.
Billing per hour worked. Time & Materials, ideal for variable scope and exploratory sprints.
Ideal for: projects with unpredictable demand or discovery phases.
Fixed fee with defined scope and schedule. Predictability for client and consultant.
Ideal for: well-defined scope and low requirement volatility.
PMO as a Service or ongoing consulting. Recurring availability and predictable revenue.
Ideal for: continuous governance, evolving integrations, or recurring support.
Compensation tied to goals. Success fee when pre-defined objectives are achieved.
Ideal for: projects with measurable ROI and win-win alignment.
Progressive equity participation. Equity with cliff and calendar for long-term partnerships.
Ideal for: early-stage startups, CTOs, and strategic advisors.
Voluntary or subsidized work for social impact, ESG causes, and community capacity building.
Ideal for: NGOs, impact initiatives, and strategic cause portfolios.
Combination of models: retainer + success fee, hourly + vesting, according to maturity and profile.
Ideal for: commercial flexibility and risk alignment between parties.
Integrations and API-first architecture in four pillars, plus project management and IT governance consulting — each block translates technical capability into business results.
System and contract mapping; non-functional requirements (latency, idempotency, resilience); patterns (API gateway, messaging, CDC). Goal: less rework and surprises in production.
Connectors, REST APIs and events, orchestration and on-demand iPaaS, ETL and streaming. Goal: delivery that scales with the business.
SLIs/SLOs for integrations, monitoring, runbooks, and incident management across vendors and internal teams. We treat integration as product — not as an isolated script.
OAuth/OIDC, secrets, mTLS when applicable, living documentation (OpenAPI, event catalog), and audit trail. Security and compliance by design, not as an afterthought.
Maturity assessment with OPM3 and ITIL. Process and effectiveness audit (not just compliance). Deliverable: Improvement Program with identified gaps and evolution roadmap.
Project Office implementation (PMO Lite to Full, or Agile). Strategic prioritization, EVM, and initiative selection. Performance metrics, dashboards, and PMO as a Service.
Incident, change, problem, and asset management (CMDB). Platform implementation (ServiceNow, Jira SM, GLPi), self-service portals, and automated approval workflows.
Waterfall, Scrum, Kanban, and hybrid models per context. EVM, CAPEX/OPEX management, procurement and contracts. Engineering and infrastructure projects with industrial risk management.
Applied artificial intelligence capabilities: from integrating models into your systems to computer vision, tailored training, and data analysis for evidence-based decision-making.
APIs, events, and orchestration to connect AI models to existing systems (ERP, CRM, data); pipelines and data governance at the edge.
Detection, classification, and image/video analysis solutions; models tailored to industrial use cases, quality, and operations.
ML pipeline design (data, feature store, training and evaluation); fine-tuning and optimization for business-specific scenarios.
Data exploration, cleaning, and modeling; dashboards, reporting, and evidence-based decision-making; preparation for ML/AI.
Integration projects where we delivered mapping, architecture, and implementation — with measurable results.
Legacy system without modern API blocked adoption of a new gateway. We delivered a REST layer with stable contract, gradual migration, and transaction idempotency.
Go-live in 8 weeks; zero duplicate incidents in the first 30 days.
Multiple channels (store, marketplace, POS) failing on inventory sync. We mapped flows, designed async events, and implemented orchestration with fallback and configurable retry.
80% reduction in inventory discrepancies after 2 months in production.
Client needed to expose stable APIs for integrators and white-label. Assessment of existing surfaces, OpenAPI documentation, and version governance.
Partner program launch in 6 weeks with defined SLAs.
Web-Engenharia officially announces the start of a new phase. We are developing robust internal solutions that, after production validation, will be launched as commercial products for up to 2 years. After this cycle, projects will be released as Open Source, allowing other companies to offer them as a service, with community support.
All projects follow the Open Telecom Platform principles — engineering and product walking together.
HEEx component library for Elixir, inspired by Radix UI and ShadCN. Unified, modern, and reusable look for all our products.
Internal system for managing our Web-Engenharia software engineers. Reusable modules: authentication, document upload, time tracking, teams, and projects.
Complete banking platform, from card issuance to payment processing. Modeled on experience with 8 traditional banks and 8 Brazilian digital banks. Built by those who understand the banking market from the inside.
AI developed exclusively for internal Web-Engenharia use. Integrated with our collaboration platform. This project will never be commercialized; our differentiator starts from within.
Platform for group travel control and management.
ERP, Mobile Digital Super app (shopping, deliveries, bank cards), POS and payment processing machine integrations.
Web-Engenharia is made by developers. Our portfolio is our own talent — with care for intellectual property, image rights, and professional appreciation of each team member.
Shared innovation. Engineering with purpose. Web-Engenharia — because the future isn't built alone.
From discovery to operation, with clear milestones and incremental deliveries.
Context alignment, system and risk inventory; definition of measurable success criteria.
API-first design, synchronous vs. event flows, decoupling, and data strategy.
Proof of concept when needed; incremental delivery with testing and observability from the start.
Planned cutover, documented handover, and continuous operation agreements.

We work where your data and processes already live: cloud, ERP, payments, and digital channels. Third-party logos only with permission and per each brand's guideline.
We integrate via exposed APIs, webhooks, queues, and batch flows when the domain requires — always with versioned contracts and production visibility.
Modernization and legacy coexistence are part of typical scope. References to Open Finance or regulated arrangements are treated as integration technical layer, without replacing client legal counsel.
Briefly describe the context (systems involved, urgency, constraints). We will reply with next steps and, if it makes sense, an alignment call.
