Workflow Optimizer
Removing friction from office and personal operations one script at a time.
Things I've built that solve real problems.
From government offices to monitoring grids.
Now
Vision Technologies & Robotics
Monitoring platforms, automation engineering, technical R&D.
2023
Independent Automation Work
Chrome extensions, RPA tooling, NAS-driven workflows.
2021
Government Office Digital Ops

Earlier
Self-Taught Foundations
HTML, CSS, JavaScript, Linux, networking — built outside any classroom.
From problem to quietly running system.
Government digital ops
Replacing paper-bound, multi-desk workflows with quietly running scripts.
Workflow automation
UiPath, VBA, and Apps Script tying disconnected tools into one motion.
Infrastructure monitoring
Dashboards and alerts that catch issues before users notice them.
Problem diagnosis
Reading logs, network paths, and human context to find the actual cause.
Process optimization
Compressing repeat work into seconds — and documenting it so it sticks.
Self-learning systems
Learning by shipping; every project teaches the next one's foundation.

Real systems, quietly running.
Beyond apps — monitoring stacks, virtualization hosts, container workflows, and self-hosted services I actively operate or explore.
Monitoring & Telemetry
Grafana dashboards, uptime probes, and structured alerts across distributed sites.
Virtualization
ESXi hosts and lightweight VMs for service isolation and lab experiments.
Container Workflows
Compose-based stacks for self-hosted services — observability, mail, and tooling.
Self-Hosted Mail
Mailcow stack for owned email infrastructure with proper DKIM/SPF/DMARC hygiene.
Edge & DNS
Cloudflare-fronted services with rule-based routing and zero-downtime swaps.
Web Hosting
WordPress and static sites on tuned LAMP/WAMP stacks for clients and personal labs.
Lightweight Data
SQLite-first storage for local-first tools and small operational datasets.
RPA & Scripting
UiPath workflows and scripted glue between desktop apps, files, and APIs.
VPS Management
Provisioning, hardening, and monitoring small fleets — the unglamorous, important part.
What's on the workbench right now.
Automation Systems
Building workflow automation using UiPath, scripting, and Apps Script glue.
Infrastructure Learning
Exploring Docker, virtualization, and self-hosted service architectures.
Monitoring & Visibility
Working with dashboards, uptime monitoring, and operational analytics.
Experimental Projects
Building practical tools for real-world operational and personal needs.

Local LLM for statement parsing
Benchmarked small models on commodity hardware — accuracy/latency tradeoffs documented.
From a village without electricity to running infrastructure.
A self-taught technologist solving real-world problems through automation, infrastructure, and relentless curiosity.
I grew up in a remote village in West Bengal, in a home that sometimes had electricity and a school that taught everything in Bengali. There were no computer labs, no mentors, no roadmap — just a deep curiosity about machines and the patience to keep poking at them.
Every skill I use today — automation, infrastructure, networking, RPA, hosting, monitoring, server environments — came from cybercafes, borrowed books, late nights, broken systems, and the quiet thrill of making something finally work.
In short
No formal technical degree — just real problems solved one at a time, until the skills added up.
The journey
2002
Foundations in a rural classroom
Strong academic results from a Bengali-medium school in a West Bengal village with limited electricity and zero formal tech exposure.
2004
First contact with computers
Started self-learning hardware, networking, and operating systems through cybercafes, borrowed books, and quiet experimentation.
2006
Local troubleshooting go-to
Became the troubleshooting lead at a local computer training institute — fixing what others gave up on.
2007
School computer education project
Built and maintained LAN infrastructure for a school computer education programme.
2008
Gram Panchayat digital ops
Joined early MGNREGA digitization work — first real exposure to running mission-critical systems for actual people.
2009+
Modifying, automating, building
Started bending systems to fit real workflows — small tools, scripts, and patches that quietly removed manual work.
Mid years
Web, hosting, infrastructure
Explored WordPress, hosting, DNS, Cloudflare, and VPS servers — moved from desktop tinkering to running services.
UiPath era
Real-world RPA at scale
Built production RPA: large-scale data entry, portal automation, scraping, API integrations, kiosks, and beneficiary systems.
Now
Infrastructure & monitoring
Focused on monitoring platforms, self-hosting, automation engineering, and scalable technical solutions.
Working philosophy
Practical over theoretical
Solutions judged by whether they hold up in real environments — not how clever they look on paper.
Self-taught mindset
Learning through experimentation, documentation, failures, and unfiltered curiosity.
Automation first
Reducing repetitive work with intelligent workflows, RPA, and small scripts that compound.
Continuous evolution
Always one step into the next thing — servers, virtualization, monitoring, Docker, infrastructure.
“I may not have a formal technical degree, but every skill I have was earned through curiosity, experimentation, and solving real-world problems.”
