Production‑First Architecture
Clean, testable, documented code built for scale from day one. Monitoring, logging, and error tracking are never afterthoughts.
Available for freelance · Remote & On-site
FullStack Developer —
Python FastAPI • IoT • ERP • SaaS
Reliable, production‑ready backend engineering — from device‑to‑cloud to the frontend. I build systems that scale, automate workflows, and secure networks.
Why work with me
Four principles that define every engagement
Full‑Stack, Full‑Pipeline
From embedded Linux firmware to React dashboards — I own the entire delivery pipeline so you don’t need a team of specialists.
End‑to‑End Ownership
Requirements gathering → architecture → implementation → deployment → monitoring. One point of contact, zero miscommunication.
100% Independent
No agency overhead, no account managers, no middlemen. Direct communication with the person writing your code.
What I Do
Eight core service areas covering the full technology stack
Backend Engineering
RESTful and GraphQL APIs with FastAPI or Django. Async workers, microservices, message queues, and database design (PostgreSQL, Redis).
IoT & Device‑to‑Cloud
MQTT broker architecture, sensor data pipelines, edge computing with Raspberry Pi / ESP32, and secure device provisioning at scale.
ERP Systems
Custom modules for Odoo and ERPNext, workflow automation, inventory management, financial integrations, and legacy system migration.
SaaS Architecture
Multi‑tenant design, authentication & authorization (OAuth2, JWT), usage metering, rate limiting, and subscription billing integration.
React Frontends
TypeScript, Next.js, Tailwind CSS, component libraries, real‑time dashboards, and admin panels that talk to your backend seamlessly.
Payment Systems
Stripe and Lemon Squeezy integration, subscription management, invoicing, webhook handling, and PCI‑compliant architecture.
VPN & Secure Networking
WireGuard and ZeroTier deployment, site‑to‑site tunnels, access control, firewall hardening, and secure remote access infrastructure.
Embedded Linux
Yocto/Buildroot customization, firmware development, GPIO and peripheral integration, real‑time data acquisition on ARM/RISC‑V boards.

Why Work With Me
What sets my approach apart
Clarity & Communication
No jargon overload, no vague timelines. You get plain‑English explanations, transparent progress updates, and a clear understanding of what’s being built at every stage.
Production‑Ready Mindset
Monitoring, structured logging, error tracking, automated testing, and CI/CD pipelines are baked into every project from the start — not bolted on after launch.
Reliability & Longevity
I don’t disappear after delivery. Long‑term maintenance, security patches, performance optimisation, and 99.9% uptime SLAs are part of the service.
Selected Projects
Real solutions delivered for real businesses
IoT
IoT Fleet Monitoring Platform
Real‑time MQTT data pipeline ingesting telemetry from 10,000+ assets. Built with FastAPI, Redis streams, and a React dashboard.
ERP
ERP Automation Suite
Custom Odoo modules automating procurement, invoicing, and inventory reconciliation. Reduced manual data entry by 80% for a mid‑market manufacturer.
SaaS
SaaS Subscription Backend
Multi‑tenant FastAPI backend with Stripe billing, 5,000+ paying users. Features include usage metering, tiered plans, and automated dunning.
Networking
Secure Mesh Network
WireGuard‑based VPN deployment spanning 50+ remote sites with ZeroTier overlay, automated key management, and central monitoring.
What Clients Say
Feedback from people I’ve worked with
“ALG Intelligence delivered our IoT backend in half the estimated time. The architecture is clean, well‑documented, and has handled 10x the initial device load without a hitch.”
“We needed a complete ERP automation suite and didn’t know where to start. The team at ALG listened, designed, and delivered a solution that saved us 80% of manual processing time.”
“Getting our payment infrastructure Stripe‑compliant was a nightmare until we brought in ALG. They refactored the entire billing module in two weeks. Rock‑solid work.”
