Aathithyan Venkatesh — Python Developer

Background

Who I Am

🏭 7 Years — German Corporate Research

Spent seven years at Altrata-BoardEx extracting and structuring data from 1,200+ German corporate annual reports — financial statements, AGM transcripts, board compositions across DACH markets. Deep expertise in structured data extraction at scale.

🐍 Python Developer

Taught myself Python entirely on my own initiative alongside my day job — building automation scripts, then Django and Flask web apps, then full production platforms with Docker, FastAPI, PostgreSQL, Celery, Redis and AWS deployment.

⚙️ Mechanical Engineer

B.E. in Mechanical Engineering with hands-on experience in CATIA V5, SolidWorks, AutoCAD, ANSYS Fluent CFD and GD&T. Practical background in composite materials testing and computational fluid dynamics.

🇩🇪 German B1 — Goethe-Institut

Certified German B1 from the Goethe-Institut. Seven years reading complex German financial and legal documents professionally. Rare combination of language skills and technical depth — ideal for DACH-facing roles.

Why I built JobPulse UK: When I moved to the UK and started applying for jobs, I hit a wall — pure silence. Instead of applying blindly, I built a platform to understand the market. JobPulse now automatically fetches 500+ UK job postings daily, analyses them with Claude AI, and tells me exactly what skills are missing from my CV. It's the project that taught me Docker, FastAPI, Celery, Redis, PostgreSQL, GitHub Actions and AWS — all in production.

🏭 Industrial Automation

🔧 BrewLine — Brewery SCADA/PLC System

Full-stack industrial automation system built from scratch. Wrote ladder logic in Siemens TIA Portal V17 for a Siemens S7-1200 PLC — pump start/stop with seal-in circuit, high temperature interlock, and automatic valve control. Simulated using S7-PLCSIM V17, tested live with Watch Table. Built the Ignition 8.3.7 Perspective HMI with live tag bindings, alarm status table (High Temperature alarm fires at 90°C), time series chart, and industrial symbol components (valves, pump, motor). Connected PLC to SCADA via S7 driver on port 102 with PUT/GET enabled.

⚙️ Autodesk CAM Post Processor Customization

Modeled a part in Fusion 360, generated Face/Pocket/Drill CAM toolpaths, and customized Autodesk's Fanuc post processor (.cps) — tracing the entry-function architecture (onOpen, onCyclePoint, canned-cycle dispatch in writeDrillCycle) to add custom program documentation and cycle diagnostics. Includes a small Python G-code parser/validator exploring modal-state tracking and safety checks.
