Benjamin Bellantonio

- Own technical vision and strategy, ensuring engineering decisions support long-term product and business objectives - Lead and develop senior engineering leaders (Heads of Engineering, Senior Managers, Staff+ ICs) to scale delivery across multiple teams - Define architectural principles, governance frameworks, and technical roadmap for core platforms and infrastructure - Partner with the executive team to align technology investments with product priorities and growth goals - Build a high-performance engineering culture focused on learning, ownership, reliability, and continuous improvement Impact: established clear technical direction, improved engineering alignment with product strategy, and strengthened organizational capability to scale

- Provided architectural leadership for strategic product initiatives across 4 cross-functional engineering teams - Created platform standards and reusable patterns that reduced complexity and improved delivery predictability - Partnered with product and leadership to drive technical alignment and ensure decisions supported long-term scalability - Translated complex system challenges into clear architectural recommendations, documentation, and decision records - Mentored Staff engineers, Tech-Leads and influenced company-wide technical direction through architectural reviews and planning sessions Impact: increased engineering velocity, improved reliability and consistency across teams, and introduced scalable design foundations for future product growth

- Technical lead for multiple feature teams responsible for architectural direction, design reviews, and system quality - Initiated platform modernization efforts aligned with new product vision, reducing technical debt and improving sustainability - Improved operational stability and observability, enabling faster incident response and higher platform confidence - Introduced systematic use of technical documentation (RFCs, ADRs) to streamline decision making and improve cross-team communication Impact: reduced system fragility, improved engineering execution quality, and established engineering practices that scaled with growth

Led the technical design, architecture of high impact / priority features across teams. Created multiple internal tools, packages and SDK’s for the microservices : distributed audit system (contextualized loggers, audit trails, database change streams), standardized error management, observability / tracing : reduced debugging/understanding time of production issues by 50% Designed an abstract file system service with tools around adapter pattern including caching strategies and on-demand backups : facilitated the transition from data containers storage to AWS S3 in 3 months Developed data processing tools and pipelines to process application logs, and aggregate in ELK Architected the Gateway service with an integrated identity provider handling multiples type of client connections (SSO, Mobile, Frontend, Public API, External users, Public pages) Worked on infra / system optimisation, load balancing strategies, nginx optimisation, cache with Redis, improved the application resiliency, speed and services availability Organized workshops about : Unit testing, OOP, SOLID, DDD : improved code quality and testing Collaborated on the strategy and processes with the CTO : helped prepare the tech department to scale Managed 10 engineers, organized performance reviews and 1-1, provided support and mentoring Built recruitment technical assessment and technical onboarding process, hired engineers

Designed and developed the user access and permission management, combined more than 200 permissions with multiple levels / scopes (based on modules and users relationships) + backend / frontend tools / libraries : helped implement complex clients specifications and facilitate engineers' work to secure APIs, services, frontend, mobile application, etc. Conceived the core system to handle hierarchies and relationships between users using tree data structure and nested set model : improved read queries performance and global application speed Created the Workflow microservice to handle tasks and validation processes (parallel / sequential validations, multiple approvers, etc.) : helped remove progressively the tool we used before and facilitated implementation of such system in any microservice Architected the Payroll module, which handle multi country policies and tax computation, generate payslips based on local regulations : successfully implemented 2 countries (Malaysia and Singapore) which helped increase the number of new clients as this module was the most requested Introduced Design Patterns and Unit testing to the team, helped with the overall code quality and flexibility, went from 5% to 30% coverage on most of the critical business rules in 1 year
