My Development Philosophy
What I've learned building production systems
Understand the Real Problem
Before writing code, I dig deep to understand the actual business challenge. Requirements often describe symptoms, not root causes.
Design for Production
Every architectural decision considers monitoring, observability, error handling, and operational requirements from day one.
Test Comprehensively
Unit tests, integration tests, and end-to-end scenarios. Automated testing enables confident refactoring and rapid iteration.
Document Decisions
Architecture Decision Records (ADRs) capture the why behind technical choices. Future teams need context, not just code.
Iterate Based on Feedback
Production metrics and user feedback drive continuous improvement. Real-world usage reveals insights that design sessions cannot.
Share Knowledge
Document learnings, mentor team members, and contribute to the developer community. Knowledge compounds when shared.

About Me
Lincoln J Bicalho
Software Engineer & AI Integration Specialist
Current Role
I'm a Software Engineer (Federal Contractor) in Germantown, Maryland, working on federal government applications. With 10+ years of public sector development experience, my focus is on enterprise .NET applications, AI/ML integration, and modernizing legacy systems while maintaining strict government compliance (FedRAMP, FISMA).
I'm currently pursuing a Master's degree in Software Engineering at the University of Maryland, deepening my expertise in advanced software architecture and AI systems.
Concurrent Ventures
Beyond my federal work, I'm building PreventX AI, an AI-powered safety platform using multi-agent orchestration. I'm implementing Text-to-SQL capabilities with Vanna AI, allowing non-technical users to query databases using natural language. I'm also working on the Bliik Platform, a multi-tenant enterprise SaaS solution built with Blazor Server and .NET Core 8.
What Drives Me
I'm passionate about making AI accessible and practical for enterprise use. I believe AI should assist experts, not replace them. My experience with facial recognition systems (2018-2019 R&D) taught me that successful AI implementation requires careful training, validation, and ongoing human oversight. I focus on building systems that provide value while maintaining transparency about their limitations.
Published Research
I'm co-author of groundbreaking research on PreventX AI, published in MOJ Ecology & Environmental Sciences. Our work explores the intersection of artificial intelligence, culture, and public health in chronic disease prevention.
- 📄 Culture Score (0-850): Measuring effectiveness to fight chronic diseases (Sept 2025)
- 📄 Prescribed Arts & Environment Ticketing: Kennedy Center case study for chronic disease prevention (2025)
Production Experience
I've architected systems that handle high-volume traffic, passed federal security audits, and maintained production systems with strict uptime requirements. I've debugged 3 AM production issues, optimized database queries that were timing out, and migrated legacy applications to modern architectures. This hands-on experience shapes how I approach every new project—with production realities in mind from day one.
"I build systems that solve real problems. My focus is on production-ready solutions that scale, maintain, and deliver measurable value. Every architectural decision considers the team that will support it and the users who depend on it."
