Advanced Geo-Mapping
Spatial Data Structures, Rendering Optimization.
World Partition, Complex Coordinate Systems.

Deep Dive: Data Optimization & World Partition

Transforming conceptual ideas into high-performance prototypes. I engineered a global hexagonal grid system where each individual cell features:

  • Procedural Cube Coordinates: Optimized (qrs) logic for pathfinding and spatial visuals.
  • Dynamic Topography: Heights mapped directly from real-world elevation data.
  • Satellite Fidelity: WorldCover colors synchronized with global satellite imagery.

By leveraging PostGIS and a Martin tile server, I streamlined the pipeline from GeoJSON to vector tiles—enabling full-world generation in seconds.

Geospatial queries? Multiplayer? I build robust, scalable solutions. If you have a technical challenge, I’ll get it done.

Backend Development, Mapping.
Full-Stack Development, Geo-Data Systems.

Deep Dive: Map Layer Integration & React development

My primary focus was bridging the gap between complex backend architecture and intuitive frontend logic. I developed the systems required to handle:

  • Animated 3D Assets: Integrated 3D wind turbine models with precise geographic placement.
  • Dynamic Layer Management: Created a system for multiple concurrent map layers, each with its own reactive, data-driven legend.
  • Data Synchronization: Ensured seamless communication between the backend and the map interface for saving and loading data.

By optimizing how spatial data is served and rendered, I created a tool that makes complex wind energy data accessible and visually engaging.

Cloud Infrastructure (AWS/Azure)
Serverless Computing, IaaS, Authentication.
Cost-Optimized Backend, Cognito-Secured APIs.

Deep Dive: Serverless & Cloud Resilience

I architect and deploy cost-optimized serverless solutions across AWS and Azure. By leveraging Infrastructure as Code (IaC), I ensure environments are reproducible, version-controlled, and highly scalable.

  • Serverless Compute: Utilizing AWS Lambda and API Gateway to build event-driven, auto-scaling backends.
  • Cloud Storage: Implementing S3 for durable, high-availability data storage.
  • Secure Identity: Managing user lifecycles with AWS Cognito, implementing robust OAuth2 / OpenID Connect flows and Role-Based Access Control (RBAC).

My focus is on maintaining modern security and compliance standards through automated deployments and the principle of least privilege.

Backend Architecture (Node.js)
System Design Maturity
Designing modular microservices & robust state synchronization.

Deep Dive: Architectural Maturity & Logic

Great backend engineering isn't just about making code run; it's about predictability and resilience. My professional experience designing scalable, modular APIs using Node.js and TypeScript has instilled a firm commitment to clean interfaces, SOLID principles, and strict dependency management. I focus on "contract-first" development, ensuring that the backend serves as a single, reliable source of truth for the entire application stack.

I prioritize decoupled subsystems—logical units that function independently, making the codebase easier to test, maintain, and scale. This maturity directly informs how I handle reliable state synchronization and high-concurrency data flows. By treating every service as a modular component, I ensure that as a project grows, it doesn't become a "black box" of technical debt.

To guarantee production-grade stability, I design unit-testable logic from day one. I don’t just build features that work for today; I architect ecosystems that are built to scale and evolve alongside changing business requirements. My goal is always the same: 0% guesswork, 100% uptime.

Database Design & Optimization
Relational/NoSQL, Indexing, Query Optimization.
Optimized Data Access, Multi-Modal Persistence.

Deep Dive: Data Modeling & Performance

I specialize in architecting high-performance data layers, balancing the strict integrity of Relational systems with the horizontal scalability of NoSQL.

  • Relational Excellence: Advanced schema design in PostgreSQL, focusing on normalization, ACID compliance, and complex Join optimization.
  • NoSQL Agility: Designing flexible, high-throughput document stores in MongoDB utilizing optimized aggregation pipelines.
  • Performance Engineering: Prioritizing Query Plan Analysis (EXPLAIN/ANALYZE) and strategic indexing to achieve sub-second latency.

Whether it’s a transactional ERP or a real-time data stream, I ensure the data model is built for integrity, speed, and future-proof scalability.

Containerization (Docker)
Deployment Reliability, CI/CD Pipeline.
Managing Unreal Build Farms, Optimizing Build Workflow.

Infrastructure: Docker & CI/CD Pipelines

I specialize in creating standardized, reproducible environments that eliminate the "works on my machine" problem. By containerizing applications, I ensure seamless transitions from local development to production.

  • Docker Orchestration: Expert in managing multi-container environments and custom networks for microservices.
  • Automated Pipelines: Designing CI/CD workflows that handle automated testing, building, and zero-downtime deployments.
  • Cloud Hosting: This portfolio and some of its live demos are self-managed on an AWS EC2 instance, utilizing Docker for high-availability hosting.

The result is industrial-grade reliability: a robust toolchain where dependencies are locked, and deployments are just a single command away.

VITO / Terrascope (Geo.Informed Module)
Angular Development, High-Performance Geo-Mapping.
Geo-expertise, Complex band calculations.

Deep Dive: Angular Maturity & Satellite Data Visualization

I contributed to the VITO Terrascope platform, specifically engineering the front-end architecture and data visualization logic within the Geo.Informed module.

  • Angular Component Design: Developed high-performance components to consume and render high-volume satellite imagery with different bands.
  • Advanced State Management: Optimized state handling to manage complex user interactions and multi-layer overlays without performance lag.

This role demonstrated my ability to translate complex data science outputs into intuitive, functional, and highly responsive geo-web interfaces.
