Vetted Unit Testing Professionals

“Frontend/full-stack engineer (~5 years) who led large-scale React + TypeScript products including a Shutterstock-like media platform with private, invite-based content and SSO-style auth redirection. Strong in performance for media-heavy experiences (thumbnails, CDN, caching, chunking) and in quality systems (Vitest, E2E, CI gates, QA/staging). Also built a complex Figma/PowerPoint-like editor with custom state management and undo/redo history tracking.”

“Backend engineer who built and evolved ConGreG8 end-to-end: a stateless Node/Express REST API on MongoDB for fast, location-based church discovery. Demonstrates strong performance and operability discipline (instrumentation, p95 latency, slow-query analysis) with a reported ~30% response-time improvement, plus security depth via JWT/OAuth and Supabase-style row-level security. Experienced in safe refactors with contract preservation, dual-read validation, and incremental rollouts.”

“Frontend engineer who has led end-to-end architecture for enterprise B2B SaaS (order management/invoicing/reporting) across web (React/Next.js/TypeScript) and mobile (React Native/Expo), with strong emphasis on quality, performance, and accessibility. Notable for modernizing a legacy React/Redux codebase with quantified improvements (15% faster loads, 65% fewer bugs, test coverage 40%→75%) and for implementing production-safe rollout practices (dogfooding, canary releases, kill switch).”

“Builder of an early-stage community marketplace, Cirkle, where they combined product and engineering ownership to ship core marketplace, membership, chat, and AI-assisted listing features. Particularly strong in pragmatic AI product development, using multiple LLMs, structured outputs, validation, and analytics to create production-ready user experiences.”

Entry-level Mechatronics Engineer specializing in robotics, automation, and ROS 2

Cali, Colombia

“Robotics software/embedded engineer who helped build an end-to-end perception sensor platform in a two-person team, owning PCB design, ROS architecture (sensor/processing/diagnostic nodes), and documentation. Experienced integrating heterogeneous sensors over CAN with Arduino and optimizing real-time performance bottlenecks (camera and high-frequency streams) using compression, grayscale pipelines, and reduced inference frequency; also containerized the system with Docker.”

“Frontend engineer with strong Angular experience who owned pricing and production management modules end-to-end at Blindmatrix. They stand out for handling complex business logic, shaping API contracts with backend teams, and improving workflow speed and data accuracy through reusable components, validation, and performance optimization.”
