Tyler Chambers

Profile

Full-stack software engineer with 10+ years of experience building financial, infrastructure, and developer-facing systems in Python and TypeScript. I routinely own product work end to end, from data models, APIs, asynchronous workflows, and infrastructure through React applications, client-side data fetching, and production rollout.

My strongest depth is in backend and infrastructure engineering, particularly systems where correctness and failure behavior matter: Bitcoin custody, authentication and authorization, distributed application workflows, and operational tooling. I also spend significant time building and thinking about AI agents, especially tool-using systems, execution environments, orchestration, and the engineering required to make probabilistic software reliable enough to use in production.

Experience

Senior Software Engineer

Unchained · Remote
Mar 2022–Present

• Led the design and implementation of Connections, Unchained’s system for sharing Bitcoin public keys and vault access between clients. Owned the project from technical design and specification through PostgreSQL models and migrations, Python services and APIs, and React/TypeScript workflows and data-fetching hooks, including sharing and revoking access across vault and lending products.

• Expanded Unchained wallets from single receive/change addresses to gap-limit address lookaheads, precomputing and monitoring addresses across both derivation paths for vault, loan, and other custody products. Reworked backend models, APIs, and React application flows that had previously assumed wallets exposed only a current and next address.

• Made vault, loan, and rekey wallet provisioning asynchronous, replacing blocking HTTP workflows with queued, retryable provisioning. This removed database-lock contention around shared Unchained keys and allowed concurrent provisioning requests to complete reliably while preserving predictable behavior for the frontend application.

• Designed and implemented Proprietary Keys, allowing Unchained and external platform participants to register multiple Bitcoin keys and control which products each key may be used for. Built the underlying key-assignment model, APIs, and React/TypeScript interfaces used to select eligible keys for vaults, loans, treasury operations, and related custody workflows.

• Worked extensively on authentication and authorization security across both application layers, including access-control enforcement, CAPTCHA and passkey flows, login information-disclosure issues, and regression coverage for security-sensitive behavior.

• Implemented Datadog APM and structured event logging across a production Flask application, replacing much of the application’s Prometheus-based observability. Instrumented latency and failure paths, managed high-cardinality telemetry, and turned previously silent failures into traceable events and operational dashboards.

Software Engineer

Pizza Hut · Louisville, KY (Hybrid)
Jun 2021–Mar 2022

• Improved reliability of an internal Python/Flask key-management service that integrated with Fortanix for HSM-backed retrieval of LUKS encryption keys.

• Tuned uWSGI, Nginx, and application timeout behavior for long-running cryptographic operations, reducing request failures from roughly 75% to effectively zero; added unit tests and established CI build/test pipelines for a service that previously had little automated coverage.

• Designed and documented a virtualized golden-image capture workflow to replace a process dependent on dedicated physical hardware. Validated the VM-based approach, documented the capture procedure, and trained engineers on the new workflow, reducing image-creation time and removing much of the hardware coordination required by the existing process.

IT Resident

Google
2018–2020

• Provided high-volume remote technical support for Google employees across the Americas, handling multiple concurrent support sessions and troubleshooting Linux desktops, developer workstations, networking, authentication, hardware, and internal tooling.

• Led Linux/Unix training for incoming IT Residents, covering Google’s internal desktop Linux environment, command-line fundamentals, system troubleshooting, and common support issues. Created and maintained operational documentation for recurring workstation problems, including recovery procedures for NVIDIA driver failures on Linux developer machines.

Borg Cluster SRE — Engineering Rotation

• Contributed production code to SRSLY (Seriously), Borg’s safe-removal service, used by SREs to coordinate potentially disruptive maintenance and removal operations across Google’s cluster infrastructure.

• Extended the service’s safety checks and operator visibility around high-risk removal operations, incorporating additional cluster state into decision-making and beginning work toward stronger warnings and authorization controls for dangerous actions.
