I am passionate about database design and visualisations in a way that it speaks for themselves. I have been helping companies create data representation, optimization and visualisation solutions by understanding business needs, not only how to make charts. I realize that data is often complicated, but it doesn't have to look that way if we design it properly from scratch. I combine my experience in data analysis, visualization, and design with the awesome capacities of Power BI to make data understandable and beautiful. My Data Stories are crafted to communicate information in the clearest, most efficient manner. I believe that the more effectively the data is presented, the more easily the information is consumed. Power BI has fantastic capabilities that allow information to be presented in an appealing, clean style, yet still contain all of its intrinsic depth and complexity. From engineering the data to the finished dashboard, I make the complex approachable. I am experienced, professional, and I have a passion for what I do. I am pleased to offer complimentary consultations online or by phone. I can also provide you with a sample visualization of your data for a nominal fee. I look forward to learning about your project and I appreciate this opportunity. I’m able to: Build Power BI report using DAX and Power Query Translate your business problem into compelling storytelling via dashboard Calculating all your metrics for your business Connecting all data sources (Database, Azure, AWS, Google Cloud, API, flat files etc) into Power BI and also build custom API connector Setting up a cloud platform for your BI reports in Azure & AWS (Refer to my other gigs!)

15+ Yrs: Legacy System Modernization for Regulated Industries | Fintech | Cloud Migration | API Integration ✅ 15+ Critical Systems Modernized | ✅ +40% Processing Efficiency Gains | ✅ Reduced System Downtime by avg. 60% | ✅ Enabled Secure Cloud Integration ⭐⭐⭐⭐⭐ “We’ve been working with Oliant, and the experience has been helpful. From the very beginning, they took the time to truly understand the vision and goals behind our service. They didn’t just build what we asked for—they offered insight and advice on what features were essential, what could be improved, and what would be needed to support.” [ Frankie Gazzano, Director], [DRS Systems] 👉 Invite me on Upwork to schedule a free 30-minute consultation to discuss your modernization challenges. I look forward to hearing from you! Struggling with outdated, unreliable software in a regulated environment like Fintech or Insurance? 😟 I'm Max Rios, founder of Oliant, and we specialize in helping established businesses in regulated sectors safely modernize their critical legacy systems. Using proven methodologies for re-platforming, cloud migration (AWS/Azure), and API integration, we transform aging software (often 10-20+ years old) into stable, efficient, compliant, and future-ready assets. We have deep experience in legacy system analysis, modernization strategies, risk mitigation, and secure software development tailored for compliance-heavy environments (e.g., HIPAA, SOC2, GDPR considerations). What does this mean for you? It means achieving tangible results like a 40% increase in processing efficiency, a 60% reduction in costly system downtime, and the ability to integrate with modern cloud services and APIs securely. This isn't just about updating code; it's about reducing operational risk, lowering long-term maintenance costs, improving security posture, and enabling your business to innovate again (like we achieved for a major financial services client, allowing them to launch three new digital products post-modernization). Maintaining legacy software (.NET Framework older versions, legacy Java, and even interfacing with Mainframe systems) is risky and expensive. Finding skilled talent is hard, security vulnerabilities accumulate, and innovation grinds to a halt. That's where we come in. We provide a structured, expert-led, "done-for-you" service, handling everything from deep system analysis and strategic modernization planning to phased migration, rigorous integrated Quality Assurance (it's standard!), and seamless deployment with minimal disruption. Here's how we help regulated businesses modernize critical systems: ✅ Legacy System Re-platforming: Expertly migrate your applications from outdated stacks (e.g., legacy .NET, Java EE, VB6, Delphi, interfaces to COBOL/Mainframe) to modern, supportable platforms (Modern .NET Core/.NET 8, Java Spring Boot, Python/Django) using proven methodologies like the strangler fig pattern to minimize risk. ✅ Secure Cloud Migration & Architecture: Strategically move critical workloads and databases (SQL Server, Oracle, DB2) to AWS or Azure, designing for security, scalability, high availability, and disaster recovery while adhering to strict regulatory compliance requirements. ✅ API Development & System Integration: Build robust, secure APIs (REST, GraphQL, gRPC) to decouple systems, connect your modernized core with internal/external services (SaaS platforms, partners), unlock data silos, and enable new digital capabilities. ✅ Data Migration & Modernization: Safely migrate critical data from legacy databases to modern platforms (Cloud SQL, RDS, NoSQL options), including data cleansing, transformation, and validation to ensure integrity and enable advanced analytics. ✅ Integrated Quality Assurance (Non-Negotiable): Comprehensive QA & testing (functional, performance, security penetration testing support, regression) is built into every phase. We ensure stability, reliability, and compliance – it’s fundamental to reducing risk in regulated environments. ✅ DevOps & CI/CD Implementation: Introduce modern development and deployment practices (Docker, Kubernetes, Terraform, Jenkins/Azure DevOps) to improve release velocity, system stability, and maintainability for your modernized applications. I'm committed to your success and ensure transparent communication and collaboration throughout the project lifecycle. We adapt reasonably to scope changes and focus on delivering true business value. What Our Clients Say: ⭐⭐⭐⭐⭐ “I've been working with Oliant's agency for over a year, and their skills have significantly grown our business." [Genoveva Grillo, CEO] ⭐⭐⭐⭐⭐ “Their integrated automated QA process caught critical issues early during our deployments, saving us significant time and potential regulatory headaches down the line. The system stability post-launch has been exceptional, exceeding our uptime goals.” [B2B FinTech for banking systems]

Hello, I am Ismael, a dedicated engineer MSc graduate from the Instituto Superior Técnico in Lisbon, always keen on learning more. Whilst I am Portuguese, I was raised in the French school system and as such I grew accustomed to a multicultural and international environment that allowed me to learn and speak 4 languages fluently. My professional and academic experience along with my internships developed both my ability to learn autonomously and to work as a part of a team, while also enhancing my critical thinking. A few years ago, I rediscovered a passion for software engineering that has allowed me to reinvent myself and I am looking for an opportunity to put my skills to use in order to grow professionally and to broaden my horizon.
