Cian Raychaudhuri

Solo developed a hosting platform / design and marketing agency with nextjs frontend and scalable fastapi backend with PostgreSQL database, stripe integration, Redis, celery workers, and customer forms api + pytest and playwright tests. All running in containers on a k3’s cluster. Built a website template using nextjs allowing a basic company website to be made with various drop in components for different sections, from start to deployed polished website within 4 hours including Google Analytics integration & forms with email notifications.

Automated lead gen, using google maps data and whatsapp business api integration.

Full Stack Software Engineer (Robotics & Automation); Embedded Systems Engineer at Vertical Future (2024-01 – 2025-08)

• Designed and implemented the full Farm Automation Software stack for a commercial vertical farm from zero to MVP in one year, enabling autonomous (human in the loop) operation, real-time data collection, and cloud-based SaaS monitoring.
• Worked across all subsystems including: Automated Seeder, Automated Harvester, Conveyor Systems, Nutrient Systems, HVAC adapting PoC scripts to fully functional, networked systems capable of being driven by a central controller via RPC & MQTT.
• Modeled and simulated farm systems including light scheduling, nutrient delivery, and robot collision avoidance to optimise performance, safety, reliability and allow automated & interactive virtual testing.
• Developed control software for a third-party collaborative robot arm to perform transplanting (moving plants from a high density tray to N lower density trays), delivering a fully functional proof-of-concept demo within one week.
• Containerised all subsystem applications with Docker, streamlining deployment and environment consistency.
• Built and maintained CI/CD pipelines (GitHub Actions) across multiple repositories
• Developed internal tools to improve developer productivity, including:
• A deployment sync tool to mirror local directories to on-site farm machines.
• A database snapshot/replay utility for test reproducibility and pre-release testing on production data.
• Test menu utilities for rapid system validation on all machines and systems.
• Designed and implemented a reliable communication protocol between farm hardware and the cloud to prevent lost or duplicate messages over Websockets.
• Integrated industrial protocols (Modbus) on SBCs for reliable hardware communication.
• Designed and managed relational databases with SQLAlchemy and Alembic, including schema migrations.
• Led API design between backend services and the frontend; contributed to UI/UX improvements.
• Maintained infrastructure, including VPN servers and DNS for development and production systems.
• Mentored junior engineers and served on the company steering committee following multiple restructuring rounds.
• Collaborated closely with frontend and mechanical engineers to improve coordination and system integration.

Embedded Software Developer at Jenoptik Smart Mobility Solutions (2023-03 – 2024-01)

• Designed and developed GraphQL and REST APIs for ANPR camera systems, for configuration, monitoring, and diagnostics through a modern GUI.
• Collaborated on API schema design and implementation using Python (FastAPI), building a modular and adaptable architecture compatible with both current and future camera products.
• Supported frontend integration by simulating platform-layer behavior, ensuring seamless API–UI communication and smooth testing workflows.
• Worked cross-functionally with C++ application engineers to integrate existing camera applications via pybindings, manage configuration files, and interface with Linux system components.
• Led migration from SVN to Git, preserving complete repository history for two major codebases and establishing improved version control practices.
• Accelerated development cycles by creating a build optimisation script that reduced API build and deploy time by 80%, significantly improving debugging and testing efficiency.
• Automated test env deployment workflows by developing a Docker-based export script, allowing stakeholders to launch test environments with a single command for each new frontend release.
• Authored technical documentation and refined internal tools to improve team workflows, maintainability, and overall development quality.

Embedded Software Engineer at Monitor Audio Group (2021-09 – 2023-03)

• Developed embedded firmware for an ESP32-based product, contributing to low-level driver implementation and graphics application logic.
• Improved and maintained firmware for two existing products, demonstrating a strong commitment to bug resolution and product enhancement.
• Co-developed Android and iOS Bluetooth companion apps for a family of Wi-Fi/BLE-enabled HiFi devices, enabling seamless device pairing and control.
• Built a scalable backend using AWS Amplify, supporting user authentication and multi-device synchronisation of HiFi systems.
• Engineered an Android Bluetooth and database abstraction layer using Kotlin coroutines, simplifying code and improving performance.
• Refactored the iOS Bluetooth stack following the MVVM architecture, collaborating with a teammate to streamline app structure and maintainability.
• Created a Python-based firmware and desktop app emulator for Linux, accelerating local development and testing cycles.
• Redesigned and maintained the internal Wiki, improving developer onboarding with clear documentation and hosting it on a Linux EC2 instance.
• Supported manual QA testing by writing test cases and implementing fixes for issues found, ensuring firmware and app releases met functional and quality requirements.
• Designed and implemented a customer service dashboard in React, providing real-time metrics and device lookup capabilities via device serial number.
