Work History

Software Development Engineer II (SDE 2)

Drongo AI Pvt. Ltd.
04.2025 - Current
  • Architected a hardware-bound licensing system that issues a single encrypted key per console, validates completely offline , and flags clock-tamper attempts —letting rural hospitals run indefinitely until the licensed expiry date with no Internet reliance.
  • Built an NSIS-based installer + auto-updater that compares local build metadata with the cloud and downloads only the delta packages needed; typical update size fell by ~70% , cutting field bandwidth and upgrade time to < 5 minutes.
  • Gated updates behind license checks and hash verification , blocking unauthorized upgrades or corrupted payloads while giving support a one-command key-renewal process; no piracy or license breaches have been reported since launch.
  • Automated activation / renewal workflow —a brief one-time connection to a secure API issues or refreshes keys, so 95% of renewals now finish remotely in under 2 minutes , eliminating costly site visits.
  • Delivered the full stack (security design, installer scripts, backend endpoints, docs) single-handedly in four months, adding ~25k LOC and creating the template Drongo AI now uses for all future offline products.

Software Development Engineer I (SDE 1)

Drongo AI Pvt. Ltd.
08.2024 - 03.2025
  • Modernized a legacy codebase into a modular, future-ready backend: untangled monolithic classes into SOLID-based service layers and DTOs, cutting average feature-add lead-time from ~5 days to < 2 days and making the codebase cloud-migration ready.
  • Built an NSIS-based, one-click installer and auto-updater for the ProRadCS console: detects prerequisites, lays down services, and—when connectivity is available—pulls and applies the latest approved build, shrinking field-deployment time from 30+ minutes of manual steps to under 10 minutes and keeping 1000+ units current with near-zero engineer intervention.
  • Rolled out ProRadCS to 1000 + consoles across hospitals and health centres; robust install-log tracing and the new one-click updater have cut backend-related support tickets to near zero and slashed on-site troubleshooting calls for field engineers.
  • Authored deployment & troubleshooting guides adopted by field engineers, standardizing roll-outs and freeing the core team from routine support questions.
  • Implemented full OAuth 2.0 / PKCE flow (Angular + Express), integrating Entra ID with JWT-based sessions and MFA enforcement—replacing the client's in-house credential store.
  • Delivered a demo-ready SSO solution in 4 weeks, enabling the client's IT team to cut new-user onboarding effort by an estimated 80% and securing sign-off for production rollout.

Junior Developer

Drongo AI Pvt. Ltd.
08.2023 - 07.2024
  • Refactored and performance-tuned the manufacturing-digitization backend, replacing ad-hoc queries with index-backed SQL and batched query patterns for pagination, and added stage-level validation to block unrealistic production counts; cut average API latency by ~60 % and delivered reliable real-time metrics to the plant dashboard.
  • Upgraded ProDigi electronic-medical-record platform (patient-management system): introduced a markup-driven template engine that streams AI and radiologist reports to on-demand PDFs (no files stored), embedded a facility-level feature-flag framework to toggle new modules safely, and rewrote the heaviest SQL joins, cutting record-view latency from multi-second spikes to sub-500 ms while enabling controlled, zero-downtime roll-outs.
  • Designed and rolled out the Cloud-Sync service for ProDigi (electronic-medical-record platform), turning a single-site EMR into an offline-first, cloud-aware system. The service receives encrypted, incremental changes to the cloud and media to AWS S3 using pre-signed URLs, auto-reconciles on reconnect, praised by management for its “unique solution” and scalable architecture.
  • Integrated Cloud-Sync across ProDigi (patient-management Electronic Medical Records) as an offline-first, batch pipeline: when connectivity returns, the service encrypts and uploads patient records, X-ray DICOM/images, AI findings, and RT-PCR reports to the cloud. This innovation unlocked seamless cloud backup, while a reverse-sync path retrieves radiologist reports or completely reseeds a wiped database, delivering remote-referral capability, disaster-recovery resilience, and a traceable audit trail without altering existing on-prem workflows.
  • Designed a multi-tenant backend for Molbio's diagnostic-device fleet (Node.js / Express + MongoDB + NATS), enabling hundreds of customer labs to register, configure, and monitor thousands of medical diagnostic devices from a single web console.
  • Implemented secure provisioning & heartbeat telemetry: token-based device onboarding, real-time health pings, and tamper-proof audit logs—cutting manual setup time from hours to minutes and giving Molbio early-warning alerts that reduce lab downtime.

Intern

Drongo AI Pvt. Ltd.
02.2023 - 07.2024
  • Learned Django + Angular in 3 weeks and shipped production code by week 4, demonstrating rapid full-stack ramp-up and the ability to contribute immediately.
  • Built the core backend for a manufacturing-line digitization platform, including architecting the database schema and REST APIs. Introduced Python decorators to enforce process-state validations, slashing boilerplate in the core business logic and boosting code reusability —forming the production-ready backend that later powered plant-wide rollout.
  • Led on-site discovery with client process & SAP teams, then implemented a toggle-able SAP push/pull connector that synchronizes production data without code changes.

  • Programming Languages: Python (primary), JavaScript / TypeScript, SQL, Bash, PowerShell
  • Frameworks & Libraries: Django, Django REST Framework, Flask, Nodejs / Express, Angular, uWSGI, Nginx
  • Databases & Storage: Microsoft SQL Server, MongoDB, MySQL, AWS S3
  • Cloud & DevOps: AWS (ECS, S3), Docker & multi-container orchestration, GitHub Actions CI/CD, NSIS Windows package installer, NATS message bus
  • Security & Auth: RSA-2048 AES-256 hardware-bound licensing, integrity-hash checks, Azure Entra ID (OAuth 20 / PKCE, MFA, RBAC), JWT session handling, Tamper detection
  • System Architecture: Offline-first / cloud-sync patterns, Event-driven micro-services, Feature-flag roll-outs, SOLID refactors
  • Machine Learning / Computer Vision: YOLO v8, MobileNet, ResNet, OpenCV preprocessing, Dataset labeling & metrics tuning
  • Collaboration & Tools: Git, SSH, Linux/Windows admin, VS Code, Technical documentation & field-engineer guides, Mentoring juniors
