Technology Stack & Systems Architecture
A comprehensive technical overview of the tools, frameworks, database standards, and security protocols powering our data solutions.
Engineering Reliable, High-Throughput Digital Ecosystems
Every system I design prioritizes data integrity, low maintenance overhead, strict compliance with data protection laws (DPDP Act), and intuitive user experiences for non-technical field staff and executive stakeholders alike.
1. Data Analytics & Reporting
Enterprise Decision Support Systems & Donor ReportingTransforming disparate relational databases, raw field survey spreadsheets, and live transaction records into unified, actionable executive intelligence with automated refresh schedules.
Custom SQL query tables, complex multi-table joins, automated data synchronization pipelines, KPI widgets, and custom donor report exports for the Gates Foundation SCALE project.
DAX calculations, star-schema dimensional modeling, interactive multi-page dashboards, hierarchical drill-downs, and institutional performance monitoring.
Rapid stakeholder visualizations connecting Google Sheets, BigQuery, and relational MySQL endpoints for accessible public and internal monitoring.
2. Backend & Databases
PHP 8.2+ • MySQL / MariaDB • RESTful APIsSpecialized in custom, lightweight PHP architectures that completely avoid the security bloat, slow rendering times, and maintenance vulnerability of monolithic third-party platforms.
Strict type declarations, modern match expressions, PDO parameter binding, zero-dependency stream socket SMTP engines, and modular CMS backends.
3NF database normalization, composite indexing strategies, InnoDB foreign key constraints, ACID transactional guarantees, and automated backup dumps.
Clean JSON endpoints, HTTP status semantics, stateless token authentication, rate limiting, and webhook ingestion for external payment or notification services.
3. Low-Code & Automation
Google AppSheet • WhatsApp Cloud API • Google WorkspaceBridging field operatives and centralized databases through intuitive mobile interfaces capable of functioning reliably under intermittent rural connectivity.
Offline-first data caching, GPS geofencing, biometric/photo capture, automated PDF reports, and barcode/QR verification workflows.
Setup and configuration of Meta WhatsApp Cloud API gateways, webhook listeners, automated message template management, and broadcast pipelines.
Tenancy management, security policies, Google Forms & Apps Script automation, spreadsheet database normalization, and institutional email routing.
4. Security & Compliance
OWASP Top 10 • DPDP Act 2023 • Cryptographic DefenseArchitected from the ground up with defense-in-depth principles to protect institutional data, prevent unauthorized administrative intrusion, and strictly comply with India's Digital Personal Data Protection Act.
Bcrypt salted password hashing, 64-character SHA-256 OTP tokens, session fixation defense with session_regenerate_id(), and strict anti-CSRF tokens.
Explicit consent logging, Data Principal rights fulfillment, designated Grievance Redressal Officer, automated data purge schedules, and zero third-party tracking.
100% prepared SQL statements, XSS context sanitization, artificial sleep timing defense on failed authentication, and max attempt caps.
