Full-Stack Technology & Growth Engineering
We engineer scalable, secure, and mathematically precise digital solutions designed to streamline complex business operations and drive commercial revenue.
Custom Web Applications
We architect high-concurrency web platforms, interactive computational calculators, client portals, and administrative dashboards tailored to specific business requirements. Built using modern PHP 8.x, responsive JavaScript, and optimized database layers.
Key Deliverables:
- Sub-25ms response time optimization with OPcache and flat-file caching
- RESTful JSON API endpoints for mobile and third-party integrations
- Role-based access control (RBAC) with granular permission trees
- Automated scheduled cron jobs for data synchronization and reporting
Mobile App Development
Intuitive mobile applications for Android and iOS that combine clean interface design with enterprise performance. We develop both native and Progressive Web Apps (PWAs) that allow instant app installation directly from the web browser.
Key Deliverables:
- Progressive Web Apps (PWA) with zero App Store commission fees
- Offline caching with Service Workers and IndexedDB persistence
- Push notifications for immediate user engagement and transactional updates
- Secure biometric authentication and OAuth login flows
Enterprise & Housing Society ERP
Tailored management software engineered to automate complex multi-stakeholder operational workflows. Our specialized Housing Society ERP complies strictly with Maharashtra Co-operative Societies (MCS) Act bylaws and housing society governance.
Key Deliverables:
- Automated monthly maintenance invoice generation with QR code payments
- Statutory 21% simple interest computation on overdue member balances
- Digital payment reconciliation, receipts, and audit-ready balance sheets
- Vendor management, work order approvals, and immutable audit logs
Meta & Facebook Ad Campaigns
Data-driven performance marketing campaigns on Facebook and Instagram. We combine engineering precision with high-conversion creative copywriting, server-side Conversions API (CAPI) tracking, and algorithmic lookalike scaling.
Key Deliverables:
- Server-side Meta Conversions API (CAPI) bypassing iOS ad-blockers
- Laser-focused custom audience creation and multi-touch retargeting
- High-converting video and image ad creative variations with A/B testing
- Real-time ROAS dashboards and cost-per-lead optimization
Financial & Bullion Feeds
Specialized mathematical and financial data integration. We engineer live benchmark synchronizations with institutional indices such as the India Bullion & Jewellers Association (IBJA), statutory GST calculations, and retail quotation builders.
Key Deliverables:
- Automated twice-daily AM/PM IBJA benchmark synchronization
- 24K, 22K, 18K, and 14K mathematical purity valuation algorithms
- Statutory BIS hallmarking fee compliance and unified 3% GST calculation
- Super Admin quotation engine with PDF print and WhatsApp dispatch
Cyber Security & Infrastructure
Hardening digital web infrastructure against attacks, data theft, and downtime. We deploy robust defense-in-depth protections across web servers, databases, and network gateways.
Key Deliverables:
- Anti-CSRF validation and parameterized SQL query defenses
- Automated IP brute-force rate-limiting and ModSecurity rule sets
- HTTP Strict Transport Security (HSTS) and Content Security Policy (CSP)
- Zero-downtime backups with atomic file-lock write protocols
The INDOSYS Delivery Lifecycle
From initial mathematical blueprint to production deployment and long-term scaling.
Architecture & Specs
We analyze the underlying business logic, calculate data workflows, define schema schemas, and eliminate computational bottlenecks before writing code.
Rapid Agile Build
Modular component development using modern PHP 8.x, robust database indexing, and lightweight, responsive UI designed for high conversion.
Security & Load QA
Rigorous testing under simulated concurrent load, anti-CSRF token verification, cross-browser audits, and mobile responsiveness validation.
Deploy & Scale
Seamless deployment to hardened servers, automated SSL/TLS installation, CDN setup, continuous backups, and performance marketing integration.
