Backend & APIs
Robust, scalable backends and APIs in Go, designed with clean architecture and built to last.
Jose Manuel Martínez Camacho
Software Developer
👨💻 Hey! I'm a software developer. I like taking a problem, turning it over, and solving it in the most efficient, precise way I can — full-stack, though I spend most of my time on the backend, where the hard parts usually live.
Currently working at BioSabor
I'm currently a software developer at BioSabor. On the freelance side I'm open to new collaborations, custom development, or any digital solution you have in mind.
What I do
Services
End-to-end development, from the database to the interface.
Real-time systems
Live dashboards and event-driven systems with SSE and WebSockets, from industrial terminals to ops panels.
Web & mobile apps
End-to-end products with React, React Native and Svelte — fast, accessible and built around real needs.
Automation & integrations
Process automation and message-queue pipelines with RabbitMQ to connect systems and remove manual work.
PROJECTS
Featured work
- Real-Time / Hospitality
Autonomous Bar Ordering System
Complete self-ordering platform for bars and restaurants. Customers order straight from their table while bar and kitchen receive and manage tickets in real time. Built around Server-Sent Events (SSE) so every screen — floor, bar and kitchen — stays in sync instantly, wrapped in a native mobile experience.
- Automation
Transport CMR Automation
Automation platform for transport CMR consignment notes that replaces manual paperwork with a reliable digital pipeline. Built on a message-queue architecture with RabbitMQ to decouple ingestion from processing, absorb load spikes, and guarantee every document is handled in order and without loss.
- SaaS / E-learning
Physiotherapy E-learning SaaS
Subscription-based e-learning platform for a physiotherapy clinic. A Go backend drives recurring Stripe billing, low-latency video streaming with signed URLs on Bunny.net, and a real-time WebSocket channel that lets students consult specialists directly. Built together with a development partner.
- Web Panel / Gaming
FiveM (ESX) Control Panel
High-performance web control panel to manage a GTA V (FiveM) roleplay server on the ESX framework — built in 2021, before standardized admin tools existed. A Go backend talks to the live game server through a custom Lua bridge, with a React admin suite and a public read-only player portal. Built together with a development partner.
- Industrial
Flowpack Production Terminal
Real-time industrial terminal that connects directly to the flowpack machine to monitor processed packages and production yields per shift. Operators log stops on screen as they occur, capturing cause and duration, with all events visible live on the dashboard.
- Web Platform
AgroVision
Agricultural management platform with satellite view for real-time monitoring of climate conditions and irrigation across multiple plots. Supports plot assignment, sensor integration, and a full agronomist dashboard to make data-driven decisions from anywhere.
- Embedded
Farm Productivity Control
Embedded system running on a Raspberry Pi connected to industrial scales. Tracks confection operations and worker yields in real time, generates per-operator performance reports, and helps production managers identify bottlenecks and optimise efficiency.
- E-commerce
Custom E-commerce Platform
Fully custom online store built with MedusaJS as the commerce engine. Includes product management, order processing, custom checkout flow, and a tailored storefront — no off-the-shelf templates, every interaction designed around the client's specific needs.

Purpose-built ERP for the meat industry with complete stock traceability using FIFO and FEFO methodologies. Manages lot control, expiration tracking, and movement history — ensuring full regulatory compliance from reception to dispatch.
- SaaS
Training & Nutrition SaaS
Dual-mode SaaS platform: B2C for individuals to log workouts and track nutrition, and B2B for personal trainers to manage clients, assign training plans, and monitor progress. Built from scratch with a focus on performance and clean architecture.
- Data & Search
Field Technician Search System — MAPAMA
Search tool for field technicians that connects to MAPAMA data sources and provides vector and semantic search capabilities. Enables fast, intelligent queries over agricultural and environmental datasets, surfacing relevant results even with imprecise or natural-language queries.
- Operations
Warehouse Quality Control
Quality management solution for horticultural warehouses that optimises pallet inspection order based on client complaint history and commercial priorities. Ensures high-risk or high-value clients are reviewed first, reducing claims and improving service levels.
- Operations
Maintenance Management System
Full-stack maintenance management platform with work order (WO) lifecycle tracking, per-technician time monitoring, and multi-user collaboration on open WOs. Features a real-time operations dashboard and AI-powered voice WO creation that automatically classifies the incident, location, and affected asset from a spoken description.
- Operations
Lean Methodology Production Dashboard
Real-time dashboard to monitor weekly production line yields under the Lean methodology. Manages an action plan with expiration dates, document attachments, and live updates — allowing team leaders to add new actions or documentation directly from the dashboard without interrupting operations.
