Software engineer with nine years in production backend systems. Currently at Motorola Solutions — RBAC engines, HA PostgreSQL, deployment tooling, cross-service integrations across the WAVE PTX platform. Outside of work, deep into harness engineering — building the infrastructure layer that wires agents to tools, memory, and the real world. Built a 24/7 autonomous agent with its own cognitive architecture, structured knowledge system, and reasoning loops. Practitioner of context engineering: designing what goes into an agent’s context window and why. Looking for roles at the intersection of agent systems and production-grade engineering.

Work Experience

Senior Software Engineer — Motorola Solutions

Aug 2021 – Present · Bengaluru, India · Engineer → Senior (Aug 2023)

WAVE PTX is Motorola’s subscription-based push-to-talk platform connecting teams across devices, networks, and locations. Worked across multiple codebases and teams — from the main provisioning portal to backend microservices to serverless device cloud infrastructure.

2026 — Microservices & Platform DB Teams

Authorization Service (Java, Spring Boot, PostgreSQL): Owned the RBAC engine controlling access for all users across the Kodiak platform — six roles, thirty-five resource types, permissions encoded as hex bitmasks. Wrote the full API integration test suite (449 test methods, 666+ with parameterized expansion, 100% endpoint coverage). Added JSR-303 validation across all request models. Refactored the monolith — split request/approval flow into its own service boundary, extracted the expiration scheduler, pulled validation logic out of controllers. Removed a deprecated role and trimmed permissions based on actual usage analysis. Built the integration between AuthZ and CAT — twelve endpoints for external request management with pagination and cross-service token validation.
pgEdge / Asset Manager PostgreSQL (Python, PostgreSQL, Patroni, pgBackRest): Helped design and validate the HA PostgreSQL backend for a new asset management service — 60TB of call recordings, two-year retention, replicated across two data centers. Built a Python wrapper around pgBackRest for automated backup/restore with monitoring (CPU, memory, disk I/O, WAL accumulation, page cache). Architecture: Active/Standby per site via Patroni, inter-site replication via pgEdge, PgBouncer for pooling, Consul for discovery. Ran the PoC end to end.
Universal Deployer (Bash): Built a deployment tool for the team’s shared test servers that became the team’s daily driver. Twenty commands (deploy, rollback, status, logs, diff, lock/unlock, snapshot, audit, fix). Multi-user safe with deployment locking, per-user timestamped backups, health checks with auto-rollback, golden image management for config drift detection.
OnePortal Security Hardening (ASP.NET Core, C#, Angular): Token sanitization and security refactoring. HTTP-only cookie enforcement, login validation hardening, JWE token cleanup across the portal’s reverse proxy, authentication surface audit.
Agentic Engineering Workshop: Ran a multi-session internal workshop on context engineering and agentic development — requested by senior management. Created slide decks, speaker scripts, and live demos. Also designed fifteen no-code agent blueprints for Google Workspace Studio.
CAT — Requests & Approvals (Java, Spring Boot): Built twelve API endpoints for external request lifecycle with pagination, expiration scheduling, and authorization integration.

2025 — OnePortal & Device Cloud Services

Kaiser Program — WiFi Enterprise Certificate Management (ASP.NET Core, C#, Angular, SQL Server, AWS S3, TypeScript, Lambda, IoT Core): Biggest feature of the year. Cross-repo effort spanning the portal and serverless device cloud. Designed DB schema from scratch (four tables, migrations, triggers, batch expiration). Full certificate lifecycle APIs — upload to S3, replace with device remapping, expiration extraction, SFDC linking. On the device cloud side, built a new Lambda handler with IoT topic rules for certificate distribution. Shipped across four environments over two months.
License Renewal & Expiry Webhooks (ASP.NET Core, C#): Subscription lifecycle event system — renewal notifications, expiry webhooks, partial renewal handling, grace period logic, self-service renewal integration, multi-region (EMEA) support.
Mototrbo R7 DualMode Device Support (Angular, ASP.NET Core, C#): Supported launch of a new dual-mode device (radio + cellular). DB migrations, registration flow changes, firmware upgrades, EMEA config. CSS integration with EVA token generation for Kodiak auth.
Reseller Portal & Bulk Operations: CSV import for mass subscriber updates, bulk deactivation, bulk corporate name updates, license allocation.
KALKI Pilot (ASP.NET Core, C#): Early access pilot — TLK140 device profile, MVNO activation/deactivation flows, reseller license allocation.
Production Incident Investigation (.NET, SQL Server, AWS CloudTrail): Independently reinvestigated a portal outage. Found the actual cause (database connectivity disruption poisoning the connection pool) after the original RCA had been accepted for months.

2023–2024 — OnePortal Full-Stack

Full-stack ownership of Motorola’s multi-tenant provisioning portal — Angular frontend + ASP.NET Core backend with 90+ database entities.

Device cloning: Full multi-zone feature — Kodiak subscriber API, group API, portal UI, notifications, RBAC, cross-zone association. Patent candidate.
Carrier transition: Managed Telna to WirelessLogic migration. New API integration, webhook updates, subscriber lifecycle changes. Received Moment Award.
Gateway management: Full UI and API for Wave PTX gateway listing, editing, and task execution.
Notification center: Redesigned with header-bar notifications, multi-app integration across OnePortal, CAT, and UGW.
EVA token & CSS integration: Enterprise Voice Auth token generation for Kodiak PTT, DCS topic integration for Cloud Services Suite.
Webhook integrations: OnePortal to DCS for real-time device state updates. License webhooks for SMP and reseller entities.
User preferences system: Cross-app preference storage with Hangfire scheduling. Used by three portals.
SMP integration: Multi-quarter work — license updates, user accounts, subscription management, reseller support.
Okta & Keycloak auth: Server-side Okta token generation, OAuth flow implementation.
.NET and Angular upgrades: Led major framework migrations across both stacks.
Load testing: 5,000 subscriber load test for bottleneck identification in Entity Framework queries.
IPR analysis: Identified seven patent candidates from the OnePortal and DCS codebases.

2021–2022 — OnePortal Ramp-Up

Migrated six MVNO carrier APIs (BeQuick, Telna, IIJ, CiscoJasper, WirelessLogic, HotMobile) from .NET Framework to .NET Core. First test coverage the carrier layer ever had.
Built the full device listing UI, device parameter configuration (WiFi, Bluetooth, APN, location, stun/unstun), and device actions — all integrated with AWS IoT device shadows.
Okta integration, Entity Framework concurrency fixes, Unit of Work pattern implementation.
By end of 2022: handling production deployments, code reviews, SIT/UAT support, and training new team members.
