Python & Microservices
Python 3.10+, FastAPI, Pydantic type validation, asynchronous HTTP clients (`httpx`), CORS architecture, and modular REST route handlers.
Application Security (VAPT)
OWASP API Security Top 10 (2023), TLS/SSL handshake analysis, HSTS/CSP security header enforcement, SSRF loopback filtering, and DNS security (CAA/SPF/DMARC).
Algorithmic Systems
Surya Siddhanta & Bengali Academy ephemeris calculations, Julian day astronomical positions, planetary orbital mechanics, and leap year compensation.
Architectural Philosophy behind AllToolss
Built on three foundational principles: Zero Tracking, High-Precision Computing, and Universal Accessibility.
1. Zero External Surveillance: Every calculation (whether chronological age, planetary positions, or Bengali panjika) executes locally with deterministic algorithms. The VAPT security scanner conducts purely non-destructive passive inspections with zero exploitation payloads.
2. Modular Polyglot Architecture: Next.js 14 delivers an ultra-fast client-side reactive experience with responsive UI and dynamic themes, while Python FastAPI handles intensive security analysis, cryptography, and backend microservices.
3. Search Visibility & Structured Microdata: Built-in Schema.org JSON-LD microdata, dynamic sitemaps, and bilingual keywords guarantee high crawlability for search engines while providing a seamless user experience.
