My professional
journey.
8+ years of engineering ownership: architecting distributed systems, eliminating database bottlenecks, and shipping resilient SaaS backends in production.
Senior Software Developer
Senior Software Developer on StoHRM, the company's core flagship HRMS (Human Resource Management System) platform serving 50k+ daily active employees across enterprise client organizations. Working in structured Jira sprint cycles with end-to-end responsibility for assigned tickets—from requirement analysis and development through QA/UAT coordination and production delivery across core workforce modules.
- Core HRMS Modules Development: Engineered major business logic enhancements across StoHRM's core modules—collaborating across teams on Attendance, Leave, Attendance Regularization, and Compensatory Off (Comp-off) to support complex approval hierarchies and policy variations.
- Inbound & Outbound Client Integrations: Implemented inbound attendance APIs to reliably ingest and synchronize client punch records, and architected outbound leave synchronization APIs from scratch to transmit real-time leave status updates to external client systems.
- 70+ RESTful APIs Across Modules: Developed and enhanced 70+ RESTful endpoints across multiple core modules, including dedicated backend endpoints supporting the StoHRM Mobile Application for seamless check-in, leave requests, and profile actions.
- Sprint Delivery & QA/UAT Coordination: Managed assigned sprint tickets end-to-end in Jira from development to release. Coordinated directly with QA and User Acceptance Testing (UAT) teams, clarifying business logic, resolving edge cases, and ensuring smooth production deployments.
Senior Web Developer & Associate
Architected and scaled the Links CRM core workflow engine for international visa filings and GetFriday operational pipelines, processing high-value customer transactions and consular document verification flows.
- Workflow Architecture: Architected Links CRM workflow engine managing 10,000+ international visa filings and consular document stages with audit trails and automated SLA notifications.
- Queue Workers & Pipelines: Engineered automated background task dispatching and queue workers for the GetFriday CRM, improving task assignment latency by 45%.
- Payment Gateways & Webhooks: Integrated Razorpay payment gateways with asynchronous webhook verification, idempotent transaction handling, and automated receipt dispatch.
- Caching & Performance: Introduced Redis caching layers for high-frequency application lookups, cutting database read load by ~35% during peak seasonal application cycles.
PHP Web Developer
Engineered Fast DMS, a custom quote-to-production manufacturing CRM for precision CNC machined parts, bridging multi-channel e-commerce orders with shop floor tracking.
- Custom Quoting Engine: Architected Fast DMS from scratch, translating complex multi-variable CNC part pricing and material specs into automated quote generation pipelines.
- E-Commerce Integrations: Integrated Shopify and BigCommerce REST APIs with automated bidirectional webhooks, syncing inventory and order lifecycle events in real time.
- Cloud Telephony & Containerization: Implemented Ziwo cloud telephony integration via REST APIs, and managed containerized local dev environments using Docker for reproducible team testing.
- Recognition: Received Appreciation Letter for delivering core manufacturing milestones 3 weeks ahead of schedule with zero critical post-launch bugs.
PHP Developer & MIS Specialist
Engineered and maintained InfoTech's core Management Information System (MIS) & Work Manager—the internal operational platform powering employee attendance, leave workflows, and automated payslip generation, alongside end-to-end task distribution for engineering projects across GIS, Underfloor Heating, LiDAR, and Photogrammetry.
- End-to-End MIS Platform: Architected the central operational MIS managing daily employee attendance regularizations, leave approvals, salary calculations, and automated monthly payslips.
- Project Categorization & File Dispatcher: Built the project management engine for GIS, LiDAR, photogrammetry, and underfloor heating contracts; automatically randomized and assigned incoming client task files across project team members.
- Active Time Tracking & QA Queue: Engineered real-time task timers recording work duration per file; once completed, files automatically transitioned into the QA queue for rigorous quality verification.
- Direct Client Server Synchronization: Developed the automated delivery pipeline that transferred QA-approved deliverable files directly to the client's internal servers for instant retrieval.
- PyQGIS Automation: Authored lightweight Python automation scripts using PyQGIS to automate repetitive desktop geoprocessing, geometry checks, and file exports inside QGIS.
- Recognition: Awarded Employee of the Month (March 2020) for outstanding system uptime and proactive workflow enhancements.

Skills & Depth of Knowledge
An honest, practical breakdown of my technical proficiencies—differentiating between what I architect daily in production, systems I ship independently, and specialized tools I learned for workflow automation.
Core Production Expertise
8+ Years Daily Architectural Ownership • Enterprise SaaS & High-Throughput Backends
PHP 8.x & CodeIgniter
Built enterprise SaaS architectures, custom MVC engines, and procedural-to-OOP refactors. Deep experience with high-load memory management and clean OOP design without starter-kit bloat.
MySQL & Query Optimization
Execution plan analysis (EXPLAIN), composite B-Tree indexing, multi-table join restructuring (cutting query latency from ~1.8s to <320ms), and concurrency lock management.
RESTful APIs & Webhooks
Designed 500+ secure REST endpoints with JWT authorization, payload schema validation, rate-limiting, and resilient third-party pipelines (Shopify, BigCommerce, Razorpay, Ziwo telephony).
Workflow State Machines
Multi-tier approval state machines eliminating race conditions for attendance regularizations, leave engines, consular visa lifecycles (10,000+ files), and manufacturing quote-to-order CRM.
Strong Practical Proficiency
Built, Shipped & Maintained in Real-World Systems • Independent & Enterprise Tooling
Go (Golang)
Built headless background daemons (ClipNest, ~14MB RAM), database CLI tools (SQL Doctor), goroutines, channels, and Go embed.
PostgreSQL & SQLite
Relational modeling in PostgreSQL (InfoTech MIS); embedded SQLite WAL mode and automated cache-pruning rules.
Redis Caching
Integrated in-memory key-value caching layers at TTK Services, cutting peak DB read load by ~35% during seasonal cycles.
Docker
Writing multi-stage Dockerfiles, managing containerized PHP/Go/DB runtimes, and building clean local compose workflows.
SVN & Git
Enterprise trunk/branch Subversion (SVN) repositories at TTK Services; standard Git/GitHub branching and release tags.
Applied Task-Specific Scripting & Automation
Targeted Tooling • Learned Specifically to Automate Real Workflows (Transparent • No Buzzwords)
Python (PyQGIS Automation)
Truthful Context: Learned targeted Python specifically to automate geoprocessing tasks in QGIS at InfoTech. Wrote concise pyqgis scripts to manipulate map layers, automate batch geometry checks, and export shapefile attributes—saving hours of manual drafting.
GIS & Spatial Pipelines
Practical working knowledge of geospatial file formats, coordinate reference systems (CRS), and the production workflow stages behind GIS, LiDAR, photogrammetry, and underfloor heating drafting projects.
Frontend Essentials
Functional, clean UI engineering using HTML5, CSS3, JavaScript, jQuery, and AJAX. Building responsive dashboards, real-time timer widgets, and interactive data tables with zero framework bloat.
