Executive Technology Leader specializing in distributed systems and multi-cloud infrastructure

Denver, Colorado, United States9y exp

“Early-stage builder who blends deep technical product work with go-to-market execution: created developer-focused platform tooling (Rust/Node/React) and at Harper moved from customer success into sales/partnerships, leading an Akamai partnership that ultimately helped close Walmart. Currently building a distributed application platform in Rust and iterating on macro-based abstractions to make Rust feel as approachable as Node.js; has not yet closed a seed round and is seeking a trusted operator counterpart.”

Junior Full-Stack Software Engineer specializing in web platforms and cloud-based systems

Boulder, CO1y exp

“Full-stack engineer with hands-on document extraction experience: built an end-to-end handwritten OCR pipeline using OpenCV + EasyOCR with spellcheck post-processing and a Tkinter-based manual correction workflow. Also brings practical distributed-systems and e-commerce reliability experience (REST orchestration, retries, logging, Stripe idempotency), and is candid about not yet shipping LLM agents to production.”

“Independent builder of production-grade systems: shipped an end-to-end URL shortener with JWT auth, Redis rate limiting/caching, Postgres, Docker, and real-time analytics, and separately architected a Redis-backed distributed task queue handling 1000+ tasks/min. Demonstrates strong distributed-systems instincts (atomicity, retries/DLQ, idempotency, heartbeats) plus a focus on maintainable code and self-documenting APIs (FastAPI/OpenAPI, versioned routes).”

“Built GynAI, an end-to-end maternal clinical decision support platform for OB/GYN practices and hospitals in North America, combining predictive ML with RAG-based LLM explainability. The candidate emphasizes real production ownership across experimentation, deployment, monitoring, and iteration, with reported impact including fewer delayed interventions in high-risk pregnancies and a 15-20% reduction in false positives.”

Intern Full-Stack Software Engineer specializing in AI and SaaS platforms

Remote1y exp

“Built Syntriq, an AI-assisted deviation investigation platform for pharmaceutical manufacturers, owning the full stack from a 13-stage Python/FastAPI AI pipeline to a React report editor with source traceability. Stands out for combining strong technical execution with deep user discovery in a highly regulated FDA-sensitive domain, and for making pragmatic product decisions based on real QA investigator workflows.”

“Engineering leader in the railroad industry who has grown from hands-on software engineering into leading four development teams across mission-critical products, while staying deeply involved in architecture and modernization. Particularly strong in transforming legacy, multi-customer enterprise systems using Java/Spring Boot, React, PostgreSQL, cloud infrastructure, and CI/CD without sacrificing delivery stability.”

“Full-stack engineer with hands-on ownership of a production cart-audit workflow redesign, spanning schema redesign, Rails APIs, and frontend navigation for non-technical operations users. Particularly strong in modernizing legacy systems safely with rollback paths and clearer data relationships, while also building AI-powered side projects using Flask, LangChain, and GPT for GitHub code analysis.”

Mid-level Full-Stack AI Engineer specializing in agentic AI and FinTech systems

Bellevue, WA3y exp

“Full-stack and AI systems engineer with a strong track record in high-stakes workflow automation and payments reliability. They’ve built production LLM systems with retrieval, validation, evals, and human-in-the-loop controls, while also shipping payment infrastructure that eliminated duplicate payouts/charges and supported 8,000+ daily transactions at 99.95% uptime.”

“Built a full-stack dependency impact analysis product ('Blast Radius') that mapped runtime service relationships and reportedly reduced deployment incidents by 40%. Also developed AI evaluation and security benchmarking systems, including WebSEC Arena and a lyric-generation tool fine-tuned on 300,000 song lyrics, with academic interest strong enough to spur a research paper effort.”

“Founding engineer at an early-stage agent marketplace who built the core job lifecycle, live run viewer, and LLM-based verification/settlement flow that gated escrow release. Also worked on a multi-agent diagnostic system using a blackboard architecture with specialized models, structured outputs, and human-in-the-loop review—showing unusual depth in both product engineering and applied AI systems.”

“Full-stack SaaS engineer with strong experience building multi-tenant analytics platforms in lean startup environments. He combines React/Node.js and Python/Django backend depth with hands-on DevOps improvements, including CI/CD and Docker adoption that cut deployment effort by nearly 50% while improving platform performance by around 30%.”

“Full-stack engineer with experience spanning enterprise document platforms and AI-powered clinical education products. Built secure TypeScript/Next.js features end to end, designed multi-model LLM workflows with validation and monitoring in production, and modernized a legacy PHP monolith through blue-green deployment and incremental migration without outages.”

“Backend engineer specializing in event-driven/serverless systems and Python/FastAPI APIs. Built a scalable PDF-to-structured-data pipeline on AWS (S3, Lambda, Step Functions, Textract, DynamoDB, SNS) with strong observability (p50/p90/p99) and reliability patterns (idempotency, retries/DLQs), and has led zero-downtime migrations using feature flags, dual writes, and incremental rollouts.”

“Backend-focused engineer who built an academic AI voice assistant with a Python microservice-style backend (speech recognition, spaCy-based NLP, and Kafka-driven automation) optimized to sub-500ms latency. Also has Sodexo internship experience deploying containerized services across Kubernetes/AWS ECS/Azure using ArgoCD GitOps, including solving config drift and secret-management challenges and supporting cloud-to-on-prem migrations with blue-green rollouts.”

“Startup-style full-stack/backend engineer with hands-on AWS architecture experience who shipped an LLM-driven assessment-question automation feature (Python microservice calling AWS Bedrock via SQS, deployed on Lambda) with strong validation/guardrails and retry strategies. Also improved production scalability by moving a CPU/IO-heavy file upload path out of a Go API into a queue/Lambda design monitored with CloudWatch, and has React+TypeScript experience optimizing analytics dashboards.”

“Built and shipped a production multi-agent LLM system at Solena that automated internal project intake, validation, reporting, and stakeholder communications using Python, SQL, and LangChain, with strong emphasis on reliability (structured validation, safe defaults, logging, and state tracking).
