API design with operational context
RESTful services, clean boundaries, CI/CD feedback loops, and observability that make production systems easier to operate.
Backend engineering / AI systems / distributed workflows
I design backend systems that turn complex business workflows into reliable software.
Fullstack software engineer with 5+ years building APIs, event-driven services, serverless workloads, contract testing pipelines, and LLM-powered products with .NET, Python, Kafka, and AWS.
5+
years in production software
.NET / Python
backend APIs, serverless services, data workflows
Banking / FX
foreign exchange workflows, APIs, and async processing
AI Systems
RAG, agents, evaluation, and LLM orchestration
Engineering profile
The portfolio should show how you think, not only where you worked.
Async systems that absorb real-world load
Kafka triggers, SQS workers, Lambda functions, and retry-aware workflows designed around throughput and failure modes.
AI products with engineering discipline
RAG pipelines, evaluation services, prompt strategy, and AI agents built as maintainable software systems.
Selected projects
Systems and products that represent my engineering work.
Real projects from banking, AI, and modernization work, presented with the problem, technical scope, and business value.
01
Banking / Foreign exchange / Distributed systems
Project Wise - FX transfers without the SWIFT dependency
Worked on a banking FX platform composed of two .NET APIs and five Python AWS Lambdas, using CQRS in the ACL layer to react to business events and orchestrate international transfers in USD, EUR, and GBP without relying on SWIFT.
- Problem
- Traditional international transfer flows can be slow, expensive, and difficult to observe across multiple systems.
- Impact
- A faster, lower-cost and event-driven FX transfer workflow, with better operational visibility through logs, traces, and custom metrics.
02
Quality engineering / Distributed APIs / CI/CD
Localiza - contract testing platform rollout
Led discovery, implementation planning, SDK integration, and training for contract testing adoption across technology teams, integrating Pact with .NET, Python, and Node.js services through CI/CD pipelines and a centralized Pact Broker.
- Problem
- Distributed APIs owned by different teams could break consumers when provider contracts changed unexpectedly.
- Impact
- Continuous contract validation in non-production environments, reducing integration risk before changes reached users.
03
AI tooling / Code quality / Developer experience
Localiza - AI code quality extension
Developed a VS Code extension integrated with SonarQube and the company OpenAI API key to analyze code findings and suggest targeted refactorings, optimizations, and vulnerability fixes directly in the pull request review workflow.
- Problem
- The company needed to reduce technical debt, but teams lacked a scalable way to drive improvements in every pull request.
- Impact
- Helped reduce technical debt by 15% in the first months of usage and supported the quarter quality goals.
Experience
Recent roles mapped to engineering strengths.
- Build REST APIs in .NET with Clean Architecture and SOLID for banking systems.
- Deliver serverless event-driven workloads with AWS Lambda, Kafka triggers, and SQS workers.
- Led contract testing rollout using Pact, PactNet, and Pact Broker across CI/CD environments.
- Develop AI agents with RAG and knowledge sources to accelerate delivery workflows.
- Architected a personal RAG system for document ingestion and conversational querying.
- Led development of an LLM benchmarking service for automated model evaluation.
- Built integrations with Hangfire and LLM services for data ingestion pipelines.
- Migrated legacy WebForms services to modern Node.js and TypeScript APIs.
- Led the rewrite of Renalegis, a legislative screening platform used by CNC.
- Built React and Next.js interfaces for government monitoring tools serving 200+ users.
