Vetted Agile Professionals

“CIO-level technology leader (most recently at Sovos) who owned the full tech roadmap across product, infrastructure, and corporate IT, scaling engineering across 14 countries with an architectural review board and standardized security/observability. Hands-on in high-severity incidents (ransomware) while managing executive/client communications, and drove a reported 40% product-velocity lift by adopting AI code assistants and agentic AI (Devin) alongside Kubernetes + Bottlerocket for secure scalability.”

“Operations and transformation leader who ran UPS Security through a major McKinsey-led restructuring, implementing a shared-services/territory-based "Patch of Land" model. Built task/time-based staffing models that enabled a 1K+ headcount reduction and $70M+ in recurring savings, earning the first UPS CEO Change Maker Award. Also mentors emerging leaders with simple, scalable operating rhythms (cadence meetings, decision frameworks, goal tracking).”

“Built and deployed a production chatbot on osvaldocalles.com and iterated through real-world LLM engineering issues: model quota/cost tradeoffs (migrating to Nova Pro), RAG accuracy via semantic chunking, AWS IAM/guardrail/security pitfalls, and Lambda/API Gateway streaming constraints (prefers JS for streaming layer). Experienced with agent orchestration using Strands SDK (AWS-focused) and LangGraph (Vercel/container deployments), plus evaluation pipelines using LLM-as-evaluator, dashboards, and staged model rollouts.”

“Director of Engineering at Proofpoint for 8 years, leading architecture and integration of Java microservices within a detection platform. Demonstrates pragmatic delivery leadership—incurring short-term cost to meet launch deadlines, then systematically paying down technical debt and optimizing AWS spend—plus a disciplined, long-horizon approach to backward-compatible API/schema evolution across many dependent services.”

“Entry-level full-stack engineer with internship experience at Amazon (Appstore IAP flow + uninstall recommendation workflow) and a health-tech startup (OneVector) where they built a DSUR reporting workflow end-to-end, including document generation, S3-backed versioning/metadata, and secure preview/download. Demonstrates strong production debugging and reliability mindset (instrumentation, deterministic retrieval, idempotent writes) and focuses on UX/performance in high-stakes user flows.”

“Senior gameplay animator with shipped AAA sports experience (NBA 2K) and WB Games experience, specializing in mocap cleanup/polish that holds up under instant replay and any camera angle. Experienced iterating animations from Maya into UE5 for validation and correct runtime triggering (state machines/blueprints), and known for preserving authentic superstar player nuance even when source data comes from messy machine-learning captures.”
