Location Tech Landing & Pricing Platform

Dynamic enterprise pricing calculator & automated checkout for location datasets

[Problem]

Enterprise prospective clients needed transparent, instant pricing quotes for complex location data without back-and-forth manual estimations across geographic regions, industry classifications, and store chains.

[Solution]

Engineered an interactive product catalog and multi-tier pricing calculation engine with automated order processing, invoice generation, and third-party payment gateway integration.

Geospatial Survey & POI Mapping Bridge

Bridging corporate survey workflows with interactive POI and home location mapping

[Problem]

Standard Zoho Survey forms lacked native map-picker and geospatial POI capture capabilities, preventing researchers from collecting accurate home coordinate data from respondents.

[Solution]

Developed a custom standalone mapping web application that receives authenticated survey session state, provides a fluid map interface for POI pin-pointing, and synchronizes geospatial coordinates back into the survey repository.

Workflow Sequence:
1.Survey Completion & Handoff
2.Interactive POI Map Selection
3.Coordinate Validation
4.Data Synchronization

2023

Location Tech Internal Data Downloader

Secure, role-based export interface abstracting enterprise data warehouses

[Problem]

Operational teams and non-technical stakeholders needed direct access to specific slices of location data without querying BigQuery directly or risking unmonitored warehouse execution costs.

[Solution]

Built a secure internal portal that abstracts complex BigQuery SQL pipelines behind an intuitive filter interface, enforcing query rate-limiting, role-based permissions, and asynchronous batch file generation.

Workflow Sequence:
1.Authenticated Access
2.Filter & Target Selection
3.Asynchronous Query Processing

AI-Powered Text Classification Platform

Operationalizing machine learning classification APIs into an intuitive business tool

[Problem]

Internal analysts manually categorized tens of thousands of customer feedback entries and product opinion lines, creating severe operational bottlenecks and human labeling inconsistencies.

[Solution]

Created a full-stack automation platform connecting machine learning classification models to a frictionless web UI, allowing analysts to upload tabular documents, select target columns, and batch-classify thousands of records instantly.

Offline-First Field Survey Mobile App

Resilient handheld survey data collection with automatic bidirectional synchronization

[Problem]

Field surveyors conducted research in underground mall sections, remote regions, and low-connectivity venues where web-based forms crashed or lost unsubmitted survey responses.

[Solution]

Engineered an offline-first Android mobile application that stores all survey questionnaires, response validations, and respondent media locally on the handheld device, automatically syncing to the centralized database once connectivity resumes.

Workflow Sequence:
1.Survey Configuration & Caching
2.Zero-Latency Offline Execution
3.Local SQLite Persistence

Cross-Border Scraping Dispatch & Notification Hub

Centralized scraping task management with Microsoft Teams webhook orchestration

[Problem]

Scraping tasks requested by overseas teams were fragmented across emails and chat messages, leading to missed URLs, unclear requirements, and untracked deliverable delivery statuses.

[Solution]

Designed and deployed a centralized request queue system with structured input schemas, automated Microsoft Teams webhook notifications, task status lifecycle management, and secure result repository.

Workflow Sequence:
1.Structured Request Ingestion
2.Instant Webhook Broadcast
3.Task Claim & Execution
