Financial Services ยท Debt Collection & Management Platform

Fintech Platform Modernisation
๐Ÿ‘ฅ40+Team
๐Ÿ“Š500+Daily Active Users
๐Ÿ“ฆ100K+Records / Import

A prominent financial services company specialising in debt collection rebuilt their core platform โ€” CollectLogic โ€” from a legacy system into a modern, cloud-native application handling complex regulatory operations at scale.

  • Architected containerised infrastructure; defined Docker/Kubernetes deployment topology on Azure AKS from scratch.
  • Designed and implemented GitHub Actions CI/CD pipelines across all services โ€” backend APIs, frontend, and integration workers.
  • Led complex database migration: schema normalisation, deduplication, and data integrity enforcement across a large legacy dataset.
  • Integrated third-party payment and data services: Live Vox, Tradeline, USAePay, Choice, and Razorpay.
  • Implemented Redis caching delivering significant, measurable performance improvements over the legacy system.
  • Coordinated 40+ team members across Dev, QA, and Leads to a successful Go-Live on April 29th 2024.
  • Defined long-term technical strategy, architectural roadmap, and cross-team design standards.
  • Drove system design reviews ensuring all new development aligns with architectural principles and NFRs.
  • Collaborated with Business Analysts to translate business requirements into concrete architecture decisions.
  • Mentored senior engineers and maintained alignment between stakeholder expectations and delivery.
Bulk Data Operations at Scale
Designed and delivered a high-throughput bulk import system supporting 100,000+ records per operation. The system handles both workflow-driven imports (via configurable business workflows) and direct generic update modules for mass record updates. Additionally, automated SFTP-based ingestion pipelines allow records to be updated from controlled SFTP endpoints configured via a third-party service โ€” enabling scheduled, zero-touch data synchronisation for client integrations.
Automated & Manual Workflows โ€” Quartz Scheduler Microservice
Built a dedicated workflow engine powered by Quartz Scheduler, deployed as a standalone microservice. The system supports both automated workflows (time-triggered or event-driven, running hands-free on schedule) and manual workflows (operator-initiated, configurable multi-step processes). Workflows orchestrate actions across the platform โ€” from data updates and bulk operations to notifications and status transitions โ€” giving business stakeholders full control over operational logic without touching code.
Custom SQL Query Module โ€” Secure Read-only Execution
Delivered a powerful in-app SQL query execution module enabling DBAs and authorised stakeholders to write and run custom SQL queries directly within the platform โ€” with results rendered inline. For security, the module is strictly read-only: all write operations are blocked at the application layer, ensuring no risk of accidental or unauthorised data modification while still giving technical users the flexibility they need for ad-hoc analysis and reporting.
Task Management Module
Built a purpose-built task system where administrators can create, assign, and track tasks for individual agents โ€” enabling structured work management across the collections team. Tasks carry priority, due dates, status tracking, and assignment history, giving supervisors visibility into workload distribution and ensuring no follow-up or action item falls through the cracks.
Role-aware Dashboards โ€” Agent & Admin Views
Designed a dual-mode dashboard system. Each agent sees a personalised dashboard reflecting their own daily progress โ€” calls handled, tasks completed, targets vs. actuals โ€” keeping individuals accountable and motivated. Admins get a consolidated team-wide view with the ability to filter by agent, date range, or metric โ€” enabling supervisors to monitor overall team health and drill into individual performance without leaving the platform.

DeviceThread is the digital backbone for hospitality properties hosting smart devices โ€” enabling owners, managers, and staff to monitor, manage, secure, and automate their entire digital infrastructure from a single platform.

  • Led backend and frontend teams across 10+ members, coordinating microservices integration across IoT device layers.
  • Introduced message queue architecture for asynchronous device event processing โ€” the foundational reliability decision for the platform.
  • Implemented caching to reduce response latency for real-time device state queries across all hotel properties.
  • Delivered platform from greenfield โ€” live across 10โ€“15 hotel properties at project close.
  • Managed containerised deployments and CI/CD pipelines via Docker and GitHub Actions on AWS.
Samsung SmartThings โ€” Deep IoT Integration
SmartThings served as the backbone of all smart device control within the platform. The integration enabled real-time monitoring and remote management of smart locks, thermostats, lighting, switches, and sensors across hotel properties. Events from SmartThings were ingested asynchronously via message queues, processed, and surfaced to staff and management dashboards โ€” ensuring no device state change was ever missed or delayed.
CloudBeds โ€” Property Management System Integration
CloudBeds provided the hospitality operations layer โ€” guest reservations, room assignments, check-in/check-out events, and billing. DeviceThread integrated deeply with the CloudBeds API so that device automations could be triggered by PMS events: room access credentials auto-provisioned on guest check-in, revoked on check-out, and thermostat schedules adjusted based on occupancy state โ€” creating a fully connected, automated guest experience.

A Decade of Growth

The Byteridge journey began in 2014 as a fresh MCA graduate joining a product consultancy. The first project โ€” Valley Proteins' Blue CRM โ€” was a trial by fire: sole developer, three years, daily client calls, and total ownership from database design to IIS deployment. It is the best possible foundation a career can ask for.

"Four years of owning every layer of a production system โ€” by yourself โ€” teaches you more than any architecture course ever could."

The years that followed brought increasing breadth. Aeries (Project Mitra) deepened full-cycle frontend ownership. Rhythmos' Unity Dockworks was an early introduction to developer tooling โ€” building .NET APIs to generate documentation directly from source code analysis. Then came Singlefile (Techstars): a contracted engagement building compliance filing workflows in a fast-moving, investor-backed environment where engineering standards were high and iteration was relentless.

The Microsoft engagement from 2020 to 2021 โ€” contributing to Bing Search and the MS Admin Portal โ€” was a defining test of quality. Working within Microsoft's engineering culture meant operating at a scale where even a small UI decision could affect millions of users. Building the "files result in work vertical" and the "Did You Mean?" suggestion service for Bing, alongside modernising location services in the Admin Portal, instilled a discipline around code quality and cross-functional collaboration that elevated every project that followed.

Back at the helm of full teams, DeviceThread in 2022 required leading 10+ engineers to build an IoT management platform from zero โ€” and the architectural decisions made there, introducing message queues for asynchronous device event handling and caching for real-time state queries, became a repeating pattern. TASC followed immediately: a crisis management platform delivered greenfield in five months with a lean team.

CCMR3 represents the culmination. Coordinating 40+ developers, QA engineers, and leads through a full fintech platform modernisation in Phase 1 โ€” then stepping up as Solution Architect to define the roadmap and deliver Phase 2 capabilities including bulk import of 100,000+ records and SFTP-driven automated data pipelines โ€” is the full expression of a decade spent building, shipping, and growing.

"From manually deploying via RDP on a physical IIS server to architecting Kubernetes-based microservices for 500+ daily users โ€” the throughline has always been total ownership."
