Vetted macOS Professionals

“Backend engineer who owned and shipped a campaign analytics API (FastAPI/Postgres/Redis/Celery) with ingestion from Instagram/YouTube, JWT auth, tests, and Docker deployment; improved performance from >1s to <150ms using precomputed aggregates and composite indexes. Experienced with Kubernetes GitOps using GitHub Actions + ArgoCD (zero-downtime rollouts, one-click rollbacks), Prometheus/Grafana observability, hybrid cloud-to-on-prem migrations, and real-time notification streaming via Redis Pub/Sub + WebSockets.”

“HR/People leader with multi-industry experience (boutique fitness, retail multi-location, bakery/manufacturing) who partners closely with senior leadership on major change. Has led acquisition integration of people systems, executed org redesign without layoffs, uses people analytics to drive leadership decisions, and manages sensitive ER investigations with a transparency-first approach.”

“LLM/AI practitioner focused on productionizing LLM assistants for customers, with emphasis on reliability, security, and data privacy (RAG architecture, guardrails, RBAC, data masking, monitoring and automated evals). Experienced in hands-on developer workshops and in partnering with sales to run tailored demos/pilots that drive broad customer adoption.”

“Full-stack engineer focused on data-heavy platforms, building Spring Boot microservices and Angular/React dashboards end-to-end. Has hands-on experience improving large-scale API and UI performance (including cutting 8–10s response times) and ensuring cross-service consistency using Kafka, idempotent consumers, and strong validation/transaction patterns on AWS with CI/CD and observability (Prometheus/ELK).”

“Built a production AI pipeline at EyCrowd to automatically grade shaky outdoor user-submitted brand videos using CV + CLIP/BLIP and a LangChain RAG layer per brand, with GPT-4 generating structured JSON explanations and grades. Optimized for latency and cost (batch PyTorch inference, caching), cutting review time from ~8 minutes to <2 minutes while reaching ~90% alignment with human graders and supporting thousands of videos/day.”

“Research assistant at St. Louis University who built and deployed a production document-intelligence RAG system (Python/TensorFlow, vector DB, FastAPI) on AWS, focusing on grounding to reduce hallucinations and latency optimization via caching/async/batching. Also developed a personalized recommendation system for the Frenzy social platform and partnered closely with product/UX to define metrics and iterate on hybrid recommenders and cold-start handling.”

“Wardrobe stylist and merchandiser with hands-on retail installation and visual merchandising experience for Dick’s Sporting Goods, using competitive analysis and sales performance tracking to justify and optimize brand/visual investments. Also has subscription box and e-commerce assortment experience, leveraging surveys and promotional incentives to collect consumer data and drive measurable traffic and sales lift.”

“Logic Pro-based music editor/mixer for short films and YouTube content who specializes in stem-driven edits to hit narrative beats (e.g., blending tension drums into a melancholy cue for a cemetery/chase sequence). Known for client-first flexibility, consistent mixes via templates/low-volume monitoring, and reliable turnaround with strong version control—work that has led to repeat collaborations with directors.”

“Sourcing/Product Development professional with deep China-based manufacturing experience who launched an eco-friendly cleaning brush line made from 100% recycled fishing nets and delivered on an Earth Day deadline. Built cost and tariff calculators to drive decisions and profitability, including improving Target private label net margins by 6 points, and runs a compliance/QC-heavy vendor qualification process (BSCI/SMETA, golden samples, third-party inspections).”

“Built an OCR backend that trains a custom Tesseract model for proprietary fonts and scales via multi-tenant isolation (tenant-scoped APIs, per-tenant storage, JWT+RBAC). Improved high-load image processing by shifting OCR to async worker queues and adding Redis caching, cutting processing time by ~66%, and also integrated Claude API to auto-generate test cases on code changes.”

“Unity VR multiplayer developer who shipped Titan Isles (Quest & Steam) and owned most networked gameplay features. Prioritized and delivered a New Game Plus feature in the first post-launch patch based on creator/review feedback and analytics, supported by automated Unity tests and live-ops triage via Unity Diagnostics and Shortcut.”

“Backend/platform engineer in fintech/payments (NexaBank/NextBank/Nexon Bank) who has built Kafka-orchestrated Java/Spring Boot microservices around a PostgreSQL double-entry ledger. Led production-critical reliability work preventing duplicate payment postings via idempotency and offset sequencing fixes, and shipped real-time ML fraud scoring (Python model API + Redis caching) with rigorous evaluation/monitoring (Prometheus) and workflow automation for dispute resolution.”

“Built and owned a production RAG search/Q&A platform at Data Integrity First for a client with a large, hard-to-search document library, deployed on AWS. Drove major adoption gains by adding source attribution (users trusted answers more) and improved system performance with guardrails, logging, and iterative chunking/OCR normalization—cutting fallback rate from ~22% to under 10%.”

“Bootstrapped founder with a technical background who has already built an MVP SaaS loyalty and referral platform plus a tablet/mobile POS companion product, leveraging Azure and Google Cloud support rather than outside capital. Focused on learning-by-building, resource-efficient execution, and forming highly motivated, equity-aligned teams.”
