Built a CLI Python tool (sanitizer.py) to sanitize sensitive data in logs and datasets before storage or analytics pipelines.
Highlights:
° Speed: Processed 82k+ lines (~10MB) in 2.2s in masking mode (~37k lines/sec).
° Security: Native Fernet encryption using Python’s cryptography library with auto key generation.
° Flexibility: Easily switch between field masking and full encryption.
Fast PII protection without slowing down processing pipelines.

Built a digital presence for Associated Engineers & Builders
I wanted this website to feel like an extension of the company itself. Organized, clear and made to last. The visual style takes ideas from blueprints engineering charts and technical papers while keeping everything simple and up to date.
I designed and developed the website around their 30+ years of work, bringing together their services, projects, history, and company story into one responsive experience.The aim was straightforward: change a construction company into a powerful modern online presence without losing its engineering roots.
Built from beginning to end. Concept, design, development and launch.
What do you think of the style😍 ?
Automated a manual Google Sheets → Slack workflow to eliminate repetitive data entry and give the team instant notifications.
Previously, new data had to be manually checked, processed, and shared across the team — slow and easy to miss. I built a Make.com scenario that:
Watches Google Sheets for new/updated rows
Processes and routes the data through a router based on conditions
Creates corresponding Trello cards for task tracking
Logs processed records back to Google Sheets
Sends real-time Slack notifications so the team is instantly updated
Result: What used to be manual checking and updating is now fully automated — saving hours weekly and removing room for human error.
Tools: Make.com, Google Sheets, Trello, Slack

Why relying on public CAs for internal infrastructure is an operational time bomb: The case for your own private Root and Sub-CA.
How many times has your engineering team been paged at 3:00 AM because an internal TLS certificate expired, taking down database connection pools, internal APIs, or background workers?
When securing internal networks, teams usually fall into one of three traps: 1. The Self-Signed Disaster: Generating ad-hoc self-signed certificates and scattering them across servers. Developers end up adding ``--insecure`` or ``insecure_skip_verify: true`` to application code, completely gutting transport security. 2. The Public ACME Workaround: Trying to use Let's Encrypt on non-routable internal hostnames (like ``.internal`` or RFC 1918 IPs). This requires leaking internal network topology to public DNS or storing sensitive DNS API credentials on every internal host. 3. The Spreadsheet Calendar: Tracking certificate expiration on calendar reminders until an un-tracked intermediate cert inevitably lapses.
Enterprise sovereign infrastructure solves this permanently with a dedicated, multi-tier Private Public Key Infrastructure (PKI):
• Offline Enterprise Root CA: An ultra-secure, isolated trust anchor that signs only subordinate issuing authorities and never touches online network traffic. • High-Availability Subordinate Issuing CAs (Sub-CAs): Domain-level issuing authorities (Dogtag PKI/FreeIPA) handling day-to-day certificate issuance. • Zero-Touch Automated Renewal: Using ``certmonger`` on Linux hosts to continuously monitor certificate lifecycles, automatically re-requesting certificates 30 days prior to expiration and reloading daemons hitlessly. • Mutual TLS (mTLS) Enforcement: Cryptographic workload identity verifying both server and client authenticity across internal database listeners, microservices, and admin interfaces.
Stop debugging expired certificates during outages. Deploy an automated private PKI foundation.
