Senior Full-Stack Software Engineer

Beamtree

Senior full-stack engineer working across Beamtree's PICQ clinical-audit platform and RISQ healthcare-analytics products, including the PICQ Analyser V2 clinical-indicator query language, with end-to-end ownership of modernization, reporting, integrations, performance, security, and delivery quality.

• Rewrote PICQ Analyser V2 from the legacy C implementation as a Ruby clinical-indicator query language used by both PICQ and RISQ: defined a Parslet grammar for numerator and denominator selectors, transformed parse trees into typed ASTs, and built a modular evaluator for comparisons, boolean logic, ranges, lists, code selectors, and domain operators such as COUNT, FIRST, NEXT TO, AFTER, BEFORE, FOLLOWING, WITH, WITH COF, IN_CLUSTER, and UNIQUE.
• Built the analyser's validation and error-reporting layer, code-extraction tooling, and versioned Redis AST cache with batch fetch/store operations, so repeated selectors are validated, parsed, transformed, and evaluated once rather than repeatedly; cache pre-warming and batching reduced processing time by 72%.
• Replatformed PICQ's legacy jQuery and DataTables clinical-audit screens as a React, TypeScript, Tailwind, shadcn, and Radix application, delivering audit and episode lists, assignment, filtering, search, sorting, pagination, bulk actions, role-aware controls, frontend testing, and CI coverage.
• Designed a governed audit-deletion and replacement lifecycle with justified soft deletion, deleted-record history, replacement episode selection, retention cleanup, and safeguards for audit eligibility and completed episodes; removed a staging-blocking bulk-operation bottleneck through transactions, batch writes, composite indexes, and query restructuring.
• Delivered RISQ healthcare analytics, including HAC Ratio Peer Comparison and HAC/COF Trend Detailed Insights with live hospital ratios, peer benchmarks, clinical filters, financial-year logic, interactive charts and tables, and PNG or Excel export; resolved domain-correctness issues across financial years, hospital hierarchies, denominators, targets, and indicator grouping.
• Created the executive RISQ Client Impact Scorecard, aggregating adoption, quality and risk outcomes, financial impact, historical trends, and opportunity data across organisation hierarchies, clinical involvement, indicators, audit activity, and previous-period comparisons; implemented its PDF output with direct jsPDF primitives.
• Established PICQ's reusable visualization platform with React on Rails, ECharts, Ruby chart builders, shared themes, caching, responsive rendering, accessibility defaults, downloads, and reusable React chart components, creating a consistent replacement path for bespoke D3 charts.
• Delivered the DRG Custom Audit product with complex episode filtering, DRG-version rules, permissions, description lookup, result selection, JSON and Excel reporting, and extensive RSpec coverage; migrated the six-tab Provider Feedback report to the new audit-workflow model while retaining scoring, DRC accuracy, financial impact, DRG comparison, and code-level reporting.
• Built secure cross-system integrations with Keycloak/JWT authentication that derives organisation context dynamically, Protobuf acknowledgement contracts and RabbitMQ publishing, and asynchronous PICQ quality-data export to an external SQL Server integration database; added 3,907 IHACPA MBS-to-ACHI mappings and backward-compatible MBS ingestion contracts.
• Co-delivered Ruby 2.7 to 3.2 and Rails 6.1 to 7.1 modernization, strengthened CSP and SAST controls by removing unsafe JavaScript, `eval`, selector-injection, XSS, and ReDoS patterns, and improved data-intensive analysis with batching, caching, memoization, indexes, New Relic tracing, and ClickHouse organisation partitioning.

Chief Technology Officer (CTO)

Handlr

Own the technical architecture, delivery, and operations of Handlr, a multi-sided service-booking platform. Remain a hands-on engineer: write production code across the stack, lead major refactors, and make the architectural decisions that shape the product and its operating model.

• Architected a TypeScript Nx monorepo with four product surfaces—customer web, partner portal, admin dashboard, and a service-provider mobile application—plus shared API, database, UI, and configuration packages.
• Established the API package as the type-safe contract boundary: tRPC routers provide end-to-end type inference to Next.js and Expo clients, while Zod schemas validate external input before domain logic or persistence.
• Designed JWT authentication and role-aware authorization for customer, partner, organizer, provider, and administrator workflows, enforcing platform-specific server procedures rather than client-side permission checks.
• Designed and implemented service discovery, organization and provider approval, availability, booking and provider-assignment lifecycles, package pricing, add-ons, reviews, notifications, vouchers, loyalty tiers, points wallets, and ledger-style transaction records.
• Integrated PayMongo hosted checkout and webhook-driven payment state transitions; retained monetary values as integer centavos and separated payment confirmation from booking fulfillment to protect financial correctness.
• Led PostgreSQL data modeling and Prisma migration work, including safe schema evolution and explicit boundaries for payment, booking, and loyalty data.
• Built shared React UI primitives and Tailwind design tokens for the web products, moving reusable behavior and visual rules into packages rather than maintaining application-specific copies.
• Delivered the Expo and React Native service-provider application while reusing platform API types and business rules to keep web and mobile clients aligned.
• Contributed production code across API, database, frontend, mobile, and infrastructure layers, leading refactors that reduce duplication and clarify monorepo package boundaries.
• Designed multi-stage, least-privilege Docker images for Node.js services, generating Prisma clients at build time and running production containers as an unprivileged user.
• Implemented branch-aware CI/CD with GitHub Actions, GitHub Container Registry, and Coolify to build, tag, and deploy four application images across development, staging, and production.
• Set standards for strict TypeScript, typed API boundaries, structured errors and logs, migration-led schema changes, Jest and Testing Library coverage, and Nx lint, type-check, test, and build gates.

Technology & Engineering Lead / Chief Technology Officer

GoGym

Hands-on CTO leading GoGym's modernization from a Xano backend and FlutterFlow application into a custom Rails, Next.js, and Flutter platform. Combine technical strategy with delivery across APIs, data migration, authorization, payments, operational tooling, dashboards, mobile reliability, and release processes.

• Directed the migration from Xano and FlutterFlow to a multi-product ecosystem: a Ruby on Rails API and admin back office, a Next.js franchisee dashboard, and a Flutter application for members and coaches.
• Established Rails 8 as the system of record with a versioned REST API for web and mobile clients, while retaining a separate Turbo, Stimulus, Bootstrap, and ERB back office for internal operations.
• Designed the backend around Ruby service objects, PostgreSQL relational models, Redis, Sidekiq and Scheduler, Blueprinter serializers, feature flags, audit trails, and Rswag request specifications that generate explicit API contracts.
• Recovered an inherited Xano migration delivered without usable migration code and with a staging database containing missing records and broken associations; rebuilt five-phase tooling for infrastructure, user accounts and profiles, subscriptions and transactions, activity history, and cleanup and reconciliation.
• Built imports with field-level mappings, batching, multi-threading, progress and error logs, connection-pool awareness, validation, and graceful handling of incomplete source data; reconstructed normalized subscriptions and transactions, and split complex source-user data into user, profile, address, assessment, wallet, image, and metadata records with references retained for reconciliation and support.
• Built memberships, tiered package and location pricing, vouchers, refunds, cash reconciliation, GoCoin wallet transactions, QR gym access, assessments, programs, classes, PT booking, leads, support tickets, and notifications.
• Integrated Xendit hosted payment links, webhooks, recurring billing, refunds, cash payments, vouchers, and GoCoin top-ups with idempotency and payment-lifecycle safeguards.
• Implemented fine-grained Pundit authorization for admins, franchise owners, location staff, and coaches through roles, assignments, capabilities, policies, database constraints, organization scoping, API checks, and regression tests.
• Designed separate Firebase-token and Rails-issued JWT authentication boundaries for mobile and dashboard clients, including secure refresh and organization selection for multi-location operations.
• Delivered franchisee and executive workflows for per-gym and cross-location analytics, revenue and member reporting, leads, sales funnels, staff and location configuration, support-ticket SLAs, task management, and financial and operational dashboards.
• Built the Next.js 15 dashboard with TypeScript, App Router, TanStack Query, Zustand, Zod-backed forms, shadcn/ui, Tailwind, Recharts, and PDF/XLSX exports; contributed Rails APIs, migrations, request and service specs, TypeScript clients and hooks, and Flutter authentication and reliability fixes.
• Structured Flutter as a Dart workspace with shared core utilities, data sources, and domain models; delivered Firebase authentication, Google and Apple sign-in, messaging, Crashlytics, analytics, secure storage, QR scanning, maps, hosted payments, and Shorebird over-the-air updates.
• Corrected early task-tenancy, RBAC, token-refresh, and Firebase-dependent authentication issues, then introduced RSpec, FactoryBot, RuboCop, Brakeman, dependency auditing, OpenAPI generation, Jest thresholds, Flutter tests, Sentry and Crashlytics visibility, feature flags, and staged releases.
• Supported Dockerized Rails, PostgreSQL and Redis operations, GCP and Coolify deployments, GitHub Container Registry images, Codemagic mobile builds, app-store delivery, and Shorebird OTA releases.
