Hi, I'm Vikas Sahu.
I craft exceptional digital experiences with clean, performant code and innovative architecture. With 3+ years of enterprise experience, I specialize in building responsive web applications, scalable backend microservices, and interactive geospatial mapping tools with Angular, Node.js, Python, and PostgreSQL. Currently developing cutting-edge spatial products at Cognitive Navigation Pvt. Ltd.
What I Do & Specialize In
A blend of frontend precision, geospatial data visualization, and scalable backend engineering.
Geospatial Development & Spatial Data Analytics
Extensive experience in architecting spatial data pipelines, vector tile rendering, and interactive map applications. Proficient in GeoServer (WMS/WFS services), GeoJSON data formats, PostGIS spatial indexing, and integrating live telemetry mapping with tools like Leaflet and MapLibre.
Web Application Development
Building performant, single-page enterprise web applications using Angular, TypeScript, and modern state management. Focused on reactive forms, component reusability, and clean architecture.
Backend APIs & Cloud Deployment
Designing scalable RESTful APIs with Node.js, Express, and Python. Managing normalized relational databases in PostgreSQL, document schemas in MongoDB, and deploying on AWS EC2 with Nginx.
Modern UI/UX Polish & Performance
Passionate about responsive design, smooth 60fps micro-animations, glassmorphism, and accessible WCAG standards. I ensure that every application not only functions flawlessly under load but also looks stunning and feels intuitive to users.

My Journey & Experience
A track record of shipping impactful software, solving challenging problems, and collaborating across agile teams.
Architecting and maintaining high-performance web applications and geospatial data intelligence systems. Managing full lifecycle delivery from frontend SPAs to spatial database queries and cloud infrastructure.
- Engineered geospatial data workflows with GeoServer and GeoJSON, accelerating spatial map layer rendering by over 40%.
- Developed performant backend microservices with Python and Node.js connected to PostgreSQL/PostGIS databases.
- Orchestrated production server deployments on AWS EC2 with Nginx reverse proxy and SSL security configurations.
- Led code reviews, version control with Git/GitHub, and resolution of complex multi-system bugs.
Angular Developer
Led the frontend architecture and implementation of JustSearch, a high-volume enterprise search and discovery platform built from scratch.
- Engineered modular Angular components and integrated Angular Material for responsive, consistent UI screens.
- Integrated complex RESTful APIs with debounced search queries and optimized client-side caching.
- Collaborated closely with backend developers to define JSON schemas and streamline data flow.
Associate Software Engineer
Contributed to the DIABOS maritime global port cost management platform, building financial reporting interfaces and data schemas.
- Built dynamic UI screens using Angular Material and responsive design principles.
- Managed and structured MongoDB document schemas for maritime port expense auditing.
- Tracked and resolved issues using Redmine while maintaining version control on Azure Repos.
