Systems Built From Scratch —
From Micro-SaaS to Enterprise ERP
I engineer real, battle-tested software systems without bloated dependencies. Follow my public build journey engineering custom ERP architectures from the ground up and launching high-utility micro-SaaS tools powered by Python, Django, MySQL, and AI-accelerated workflows.
Invoza — Free Online Invoice Generator
Create professional, GST-compliant invoices in under 60 seconds with zero friction. Engineered with 8 MS Word-style templates, intra-state CGST + SGST tax split calculations, automatic number-to-words currency formatting, and instant PDF download.
from apps.invoza.models import Invoice
from reportlab.platypus import SimpleDocTemplate
# Production-tested calculation pipeline
def generate_gst_invoice(payload):
taxable = payload.subtotal - payload.discount
cgst, sgst = split_tax(taxable, rate=0.18)
pdf = compile_reportlab_stream(payload)
return HttpResponse(pdf, content_type="application/pdf")

Engineering Philosophy
Software breaks when developers treat infrastructure like a toy. We build resilient, high-throughput systems on rock-solid fundamentals.
Python, Django & MySQL
The battle-tested backbone of high-scale web platforms. We leverage Django 6.1 LTS with MySQL for strict ACID compliance, declarative database migrations, and clean modular app boundaries.
AI-Accelerated, Human-Architected
We use AI to 10x development velocity, draft comprehensive test suites, and write high-converting copy. But data models, security perimeters, and relational transactions are rigorously human-architected.
Pragmatic Modular Monolith
Microservices introduce operational chaos before product-market fit. We build clean modular monoliths that can easily scale horizontally, with dedicated domain apps and zero network latency.
