Core Capabilities & Impact

Whether advising as a consultant or leading an internal engineering squad, I deliver architectural solutions engineered for resilience and enterprise scalability.

Cloud Architectures

High-availability multi-cloud design with Terraform as Infrastructure as Code (IaC). Hexagonal architectures (Ports & Adapters) and event-driven backends that isolate core business logic.

AWS / GCP / Azure / Terraform

AI Architectures & Agentic Workflows

Implementation of advanced agentic orchestration frameworks, custom model-agnostic MCP servers, RAG platforms, Bedrock, Vertex AI, and highly resilient LLM-as-a-Judge evaluation pipelines.

LangChain / Bedrock / Vertex / Python

Offline-First Mobile Apps

Highly robust React Native and Expo local-first ecosystems supported by Drizzle ORM and SQLite, with persistent communication singletons and sync systems.

SQLite / Drizzle / React Native

Observability & Security

Technical Leadership & System Design

Staff Software Engineer & AI Consultant. I transform complex architectural ambiguity into high-performance, production-ready systems, helping enterprises scale distributed platforms and modernize engineering teams with secure, high-velocity Agentic workflows. Open to high-impact consulting engagements and strategic leadership roles.

For over a decade, I have partnered with global organizations to drive system modernization and AI adoption. My approach to Agentic Software Engineering goes beyond using AI as an assistant—it’s about establishing the strategies and culture for high-velocity, secure delivery. I bring my own robust methodology that aligns with industry-leading practices: I empower AI agents with strict guardrails, context resources, tools, and standardized guides, just as a Tech Lead mentors a human team. I adapt seamlessly to engineering squads, always striving to contribute, mentor, and multiply the entire team's velocity and capabilities.

Beyond the code, I bring deep consulting instincts, intellectual honesty, and enterprise maturity. I know the difference between what an agent can generate in 10 minutes and what requires foundational architectural thinking, guiding organizations with robust methodologies like TOGAF. I treat AI-generated code with absolute professional accountability, enforcing strict human and AI audits, cross-validation, Test-Driven Development (TDD), and adherence to the OWASP Top 10 for AI & LLMs and the OWASP GenAI Security Project, ensuring highly secure and precise enterprise solutions.
