Multi-Blockchain Token Bridge
Built a configurable bridge framework connecting Ethereum with two proprietary blockchains so their native currencies could be represented and used in Ethereum's broader DeFi ecosystem.
Software Engineering for Complex Systems
We help companies design, build, and improve complex software systems—from backend architecture and distributed platforms to production AI applications.
Architecture first. Production always.
Libélula Software is a boutique software engineering consultancy centered on architecture-first thinking and production reality. We bring senior technical judgment to systems that need to be reliable, understandable, and ready to evolve. Our work favors direct communication, pragmatic technology choices, and maintainable designs over novelty for its own sake.
Some software problems cannot be solved well by focusing on implementation alone. An existing system may have become difficult to change, an integration may involve incompatible models or constraints, or a performance or reliability problem may require investigation beyond an isolated component. We help teams understand the system and its requirements, determine what needs to change, and carry the solution through implementation.
Libélula is led by an engineer with nearly a decade of experience at Microsoft building high-performance C++ server and cloud systems, followed by founding engineer and CTO roles at startups. Since 2021, Libélula has brought that experience directly to client systems.

Coinbase Mesh API Adapter
Built a lightweight server to adapt requests between Coinbase and native blockchain APIs, focused on the capabilities required for the client's exchange integration.
Multi-Blockchain, Cross-Language SDKs
Replaced a fragmented collection of blockchain SDKs with consistent Python and JavaScript implementations backed by a shared serialization model.
Latest Insights
Notes on architecture, production software, and applied AI engineering.
What Does This Test Actually Prove?
Different testing strategies reduce different sources of uncertainty.
Production evidence can further improve both the product and how it is tested.
Performance is an Architectural Property
Measurement identifies where resources are being consumed.
Understanding why those costs exist determines where to intervene.
Complexity Has to Earn Its Place
The right level of software complexity is a Goldilocks problem.
Too little and too much can both create technical debt.
Judgment matters even more with AI-assisted coding.
Have a difficult software problem?
Tell us about the outcome you need, the current system, and the constraints that matter.
You do not need a finished specification.
Work can include focused architecture reviews, implementation projects, and ongoing technical guidance.
We can work independently or alongside an existing engineering team.
