Personal Projects

Osteopath appointment booking platform

Online scheduling for osteopathic clinics (placeholder)
cabinetosteopathielrda.fr
  • Designed an end-to-end patient booking flow: practitioner/service selection, real-time availability browsing, and appointment confirmation.
  • Implemented availability management with configurable working hours, breaks, exceptions (holidays/closures), and appointment duration rules per service.
  • Built double-booking prevention using server-side validation and transactional booking (atomic slot reservation).
  • Developed self-service rescheduling/cancellation flows with configurable cutoff windows and automated slot release.
  • Added automated email notifications for confirmations, reminders, and changes, with templating and locale-ready content.
  • Implemented secure authentication for practitioners/admins and an admin console to manage practitioners, services, schedules, and bookings.
  • Designed a data model for multi-practitioner (and optionally multi-clinic) operations: rooms/resources, service catalog, and patient records (minimal data).
  • Added audit logging and traceability for booking lifecycle events (created/updated/cancelled) to support support/debugging.
  • Applied GDPR-friendly practices: minimal data collection, consent/retention settings, export/delete workflows (as applicable).
Stack:NuxtJsNodeJsMongoDB

Highlights

  • Calendar/slot generation strategy (timezone-aware), with efficient queries for availability windows and capacity.
  • Transactional booking and concurrency handling to prevent race conditions on popular time slots.
  • Role-based access control for back-office features (practitioner vs admin), with server-side authorization checks.
  • API-first design (REST) with documentation (OpenAPI/Swagger if applicable) and DTO validation.
  • Reliable notification pipeline (retries, idempotency keys, delivery status tracking) for booking messages.
  • Security hardening: input validation, rate limiting on booking endpoints, and protection against enumeration of patient data.
  • Observability: structured logs + correlation IDs for booking requests (and metrics if applicable).

Trading bot

Ichimoku-driven trading decision engine for MT5 (signals + automation plumbing)
active
  • Built a Multi-thread Java/Spring Boot “decision engine” Application that computes Ichimoku indicators from OHLC market data and produces trading signals,
  • Extended the indicator pipeline to support additional filters used in the decision process (e.g., RSI, MACD, ATR) to avoid low-quality setups,
  • Implemented a companion Python/Flask bridge to MetaTrader 5 to retrieve trading/account data and market history, and to exchange runtime events with the MT5 side,
  • Exposed operational endpoints used in tests and integration,
  • Designed the system as a deployable service on a VPS (Linux) with containerization and service management (Docker Compose + systemd) to keep MT5 bridging and the decision engine running reliably,
  • Added monitoring and troubleshooting tooling around the stack (Prometheus/Grafana + centralized logs via Loki/Promtail) to debug connectivity, runtime stability, and API behavior.
Stack:Java 21CI/CDSpring BootPythonFlaskMetaTrader 5Docker / Docker ComposePrometheusGrafanaLoki / Promtail

Highlights

  • Separation of concerns: Decision engine (Java) vs broker/terminal bridge (Python/MT5) to keep trading logic independent from execution plumbing,
  • Creation of CI/CD pipelines for faster and safer releases
  • Indicator-first design: Ichimoku core + optional momentum/volatility indicators feeding a single decision layer,
  • Production-oriented operations: containerized deployment, restart policies, health/heartbeat flows, structured logging for diagnosis,
  • Observability: metrics scraping and dashboards (Prometheus/Grafana) + log aggregation (Loki/Promtail) to investigate “silent” failures and long-running stability issues.

Meal Planner app

Meal planning + grocery list (placeholder)
glawnickmeals.com
  • Built a JWT-based authentication flow (login, register, “me” profile endpoint) with a custom OncePerRequestFilter,
  • Implemented role-based access control at two levels : Application roles (e.g., USER, ADMIN, SUPER_ADMIN) for admin capabilities (user management, nutrition catalog administration). and Group-scoped roles (e.g., OWNER, ADMIN_GROUPE, MEMBER) with permission checks via a dedicated authorization component,
  • Developed Group management APIs: create groups, invite/remove members, list memberships, update member roles,
  • Created Weekly meal planning APIs based on date ranges (current week, range queries, day upsert, filled-dates listing, available years),
  • Built Grocery list workflows per group (CRUD + “bought” toggle + bulk cleanup) and designed a service layer capable of generating groceries from weekly meals / recipe ingredients (aggregation logic),
  • Implemented Recipe management with nested structures : Recipe + RecipeIngredient + ordered RecipeStep and Computed values such as kcal per serving from ingredient quantities,
  • Added a Nutrition item catalog (NutritionItem) including unit conversion metadata (unit → grams / mL) to support ingredient normalization,
  • Implemented password reset workflow with persisted tokens and email sending (fallback to console output when mail sender is not configured).
Stack:Java Spring BootReactCI/CD

Highlights

  • Spring Security (JWT, AuthenticationManager, custom filter, method-level security via @PreAuthorize),
  • Spring Data JPA / Hibernate (UUID entities, relationships, repositories, custom JPQL/native queries),
  • MapStruct (DTO ↔ entity mapping),
  • OpenAPI/Swagger annotations (io.swagger.v3.oas.annotations),
  • CORS configuration (backend-controlled origins, headers, credentials),
  • Layered design: Controllers → Services → Repositories, with DTO mapping using MapStruct,
  • Persistence model for collaboration : Users, Groups, GroupMembership (role per group), Weekly meals stored per group and unique per date, Groceries tied to group and created-by user, Recipes with ingredient and step sub-entities,
  • Defensive JWT handling to avoid breaking CORS headers when user lookup fails.
