Matt Atencio

Building secure, scalable platforms that drive business outcomes in regulated industries. 12+ years turning complex integration challenges into reliable systems serving millions.

About

I'm a Senior Software Engineer and Integration Architect with over a decade of experience designing and delivering cloud-native fintech platforms in highly regulated environments. My work sits at the intersection of engineering, product, and business strategy—bridging technical depth with organizational impact.

At Sagent, I architect multi-tenant microservices for a mortgage platform serving millions, lead authentication modernization initiatives, and serve as first-line incident commander. Previously at DCU and First Financial, I drove CRM transformations, mobile banking modernization, and regulatory automation.

“Driven by curiosity and a belief in lifelong learning, I solve problems by asking the right questions, visualizing complex systems, and connecting the right people. My success comes from identifying gaps in process, tools, or teams—and closing them through leadership, design, planning, and collaborative execution.”

Featured Work

Selected projects that demonstrate business impact and technical depth

LearnPod
A personal learning system that turns saved content into a compounding, gamified knowledge graph
  • Learning-science foundation: SM-2 spaced repetition, retrieval-practice-first home (reviews surface above new content), 70/30 interleaved review questions, and first-attempt accuracy bonuses that reward genuine mastery over grinding
  • Pod / Module content model: atomic one-idea Pods for clean retrieval targets, Modules for scaffolded mini-courses, domain taxonomy across AI Engineering, Quant, ML, Business and more — designed to scale from ad-hoc captures to structured learning paths
  • Engagement engine built on the Hook Model: streaks with freezes, repair, and milestone tiers (Bronze/Silver/Gold/Diamond at 7/30/100/365), daily XP goal with Casual/Regular/Intense commitment tiers, celebration overlays with particle confetti, and domain-accuracy tracking as the substrate for adaptive personalization

Deposit Networks
A category case study on the API-first rewiring of wholesale deposit liquidity

Public research artifact. Written as an engineer's honest appraisal of an emerging fintech infrastructure category — what makes the wedge real, what the structural risks look like, and how I'd build in it if I were on a founding team.

  • Category map of reciprocal deposit and wholesale liquidity infrastructure — incumbents, challengers, and the wedge post-SVB
  • Concept UI exploring the three operator personas a platform in this space has to serve: treasury, controller, and network admin
  • System architecture decomposing a regulated network platform into services with clear trust boundaries and failure modes
