Subid Das
Cloud Native Engineer & Systems Architect bridging Kubernetes infrastructure, enterprise AI pipelines, and high-performance software.
Currently based in India, operating globally. Software Engineer at Connect In Cloud, overseeing production infrastructure at 99.999% uptime and contributing actively to CNCF and Kubernetes ecosystem projects.
Engineering Background & Focus
My journey began with hands-on systems programming and full-stack software development, evolving into a deep specialization in distributed cloud-native systems, automated infrastructure, and enterprise AI orchestration.
At Connect In Cloud, I take direct operational ownership of 5+ production cloud environments with zero tolerance for downtime, managing automated container clusters, database replications, and SSL/TLS edge routing. Concurrently, I’ve delivered production software for major clients, including ridenoww.com (a multi-tenant transport platform on mobile and web) and deedpollservices.co.uk (a high-conversion legal services platform handling automated document generation and Stripe settlements).
During my tenure with Indian Oil Corporation Limited (IOCL), India's flagship energy enterprise, I engineered an AI-assisted document audit and validation engine. By combining LangChain schema extractions, Pinecone vector indexing, and RabbitMQ message queues, the system autonomously processes 5,000+ contracts every month with strict compliance policies, reducing manual legal and operational review overhead by 90%.
With M.it services & systems GmbH (Germany), I focused on low-level systems engineering and cross-platform native capabilities. I refactored their Rust and Tauri desktop overlay architecture, migrated core APIs to official Windows bindings, and developed zero-latency native media streaming pipelines for iOS and Android using CameraX and AVFoundation.
Core Disciplines & Technical Depth
Cloud-Native & Kubernetes Infrastructure
Architecting multi-cluster production environments with 99.999% uptime guarantees. Expertise in container orchestration, ingress routing (Traefik, Nginx), GitOps workflows, automated zero-downtime rollouts, and persistent storage management across Linux distributions and cloud VPS providers.
Enterprise AI & Document Intelligence
Building deterministic AI validation engines and schema-driven RAG pipelines. At IOCL, designed systems parsing 5,000+ contracts monthly using LangChain, Pinecone vector stores, and RabbitMQ message brokers, eliminating 90% of manual enterprise audit time.
Low-Level Systems & Native Performance
Systems software development in Rust and Go. Engineered native cross-platform media capture for Android (CameraX, MediaProjection) and iOS (AVFoundation, ReplayKit) within Tauri runtimes, Windows API migrations, and deadlock-free concurrent IPC subsystems.
Resilient Full-Stack Architecture
Delivering end-to-end consumer and enterprise products. From production legal platforms with Stripe payment reconciliation (Deed Poll Services) to UK ride-hailing networks (ridenoww.com), combining Next.js 16, SurrealDB, BullMQ queues, and React Native mobile clients.
CNCF & Kubernetes Contributions
Add TSDB Admin page to Mantine UI
Added a new 'TSDB Admin' page providing a web interface for `delete_series` and `clean_tombstones` admin API endpoints.
Migrate test suite to Ginkgo v2 + Gomega
Migrated the entire test suite from legacy patterns to Ginkgo v2 and Gomega, introducing BDD-style assertions.
Fix ReadWriteMany PVC workload grouping
Introduced an `isNonGrouping` flag to prevent ReadWriteMany PVCs from incorrectly merging unrelated workload groups.
Client-side nanosecond timestamp capture
Implemented client-side timestamp capture with nanosecond precision for pod latency measurements.
Architectural Principles
Reliability Over Hype
A system that isn't dependable in production doesn't matter. I design distributed infrastructure with redundancy, automated health checks, bounded queues, and graceful degradation strategies before optimizing for speed.
Observability As A Core Contract
If telemetry isn't real-time and actionable, troubleshooting is guesswork. Metrics, structured logging, and distributed tracing are integral to software delivery from day one, not bolted on after an outage.
Deterministic & Idempotent Automation
Manual intervention in deployment or failover is an operational vulnerability. Infrastructure should be codifiable, reproducible in any environment, and provably idempotent across configuration states.
Upstream Open Source Stewardship
The foundations of modern infrastructure rely on open source. Contributing fixes, test suites, and UI tooling directly to CNCF upstream repositories ensures ecosystem longevity and deep protocol understanding.
Work History Highlights
Systems Software Engineer
atM.it services & systems GmbH (Germany)- Audited and refactored a Rust + Tauri codebase, eliminating dead code, enforcing idiomatic patterns, and restructuring module visibility, while migrating all Windows-specific bindings from windows_api to the official windows crate with zero functional regressions.
- Enabled cross-platform mobile builds (iOS & Android) by configuring Tauri targets, resolving conditional compilation issues, and establishing platform gateways under tauri/src/platform to ensure platform-specific code is never shipped to other targets.
- Built a Rust-based mock frontend exercising all #[tauri::command] functions with simulated input/output flows, supporting 20+ concurrent invocations with no deadlocks, race conditions, or resource leaks.
- Implemented native mobile media capture (screen share, camera, microphone) for Android using MediaProjection, CameraX, and platform audio APIs, and for iOS using ReplayKit and AVFoundation, with just-in-time permissions, lifecycle-aware capture, and structured error propagation from native → Rust → frontend.
Software Development Engineer
atIndian Oil Corporation Limited (IOCL)- Built a configuration-driven internal document intelligence platform enabling enterprise employees to upload unstructured PDFs, extract structured data, and validate information, reducing manual audit effort by 90%.
- Implemented LLM-driven, schema-based extraction and RAG pipelines using LangChain and Pinecone, allowing extraction fields, schemas, and normalization rules to be modified declaratively without changing core extraction logic.
- Designed an LLM-assisted, rule-based validation engine supporting existential, cross-entity, semantic, and policy validations, with all rules extensible without modifying validation orchestration code.
- Orchestrated asynchronous extraction and validation workflows using RabbitMQ, improving processing throughput by 3× while producing auditable validation reports.
