01About me
MTS-3 (Senior Software Developer) at Aquera — focused on system integrations and automation — and the reusable engine underneath them.
Code connects people.
02Featured work
NDA-bound work as high-level case studies, my own product, and builds that push AI, full stack and system design.
Connected HR systems, Active Directory and Microsoft Entra into one reliable onboarding / offboarding flow for enterprise customers.
Improved the core engine so new connectors — ADP, Greenhouse, UKG, Dayforce, Workday — get built in days, not weeks.
Gave every AI tool a role — requirements, architecture, build, QA, reporting — coordinated as one workflow with human review at each step.
Turning screen time into skill time for kids — from an idea to a live, working platform.
Visit zungga.comSpecialist AI reviewers for security, performance and style, coordinated by an orchestrator into one consolidated review — a human approves before anything merges.
Retrieval-augmented assistant over connector docs and OpenAPI specs — answers integration how-to questions and cites the exact source section.
Reads an OpenAPI spec, generates edge-case test suites, runs them against the API and reports the gaps it found.
Shared canvas with live cursors, rooms and instant sync across users, with authentication and saved boards.
Admin platform with tenant isolation, role-based access, audit logs and usage analytics dashboards.
Queue-based sync engine with retries, idempotency, dead-letter queues and rate limiting — designed so one failing system never blocks the rest.
Daily rhythm
My daily commits, customer calls and AI work happen in private work systems, so these are illustrations of my rhythm — not live data.
03More builds
Personal and learning projects from my full-stack track. Small, honest, and still running.
Drag-and-drop flow designer that compiles into executable integration pipelines, with step-level logs and replay.
Token-bucket limiter shared across service instances — fair per-tenant quotas without a single point of failure.
Signed webhooks with exponential retries, idempotency keys and a dead-letter queue for failed deliveries.
Ingests service logs, indexes them for search, and raises threshold alerts before customers notice.
Turns meeting transcripts into structured action items and drafts tickets for human review.
Progressive web app that works without a network and syncs safely with conflict resolution when back online.
Built during college and my early learning years, written by hand without any AI assistance.
Full-stack web app for running a college placement cell.
Web app for managing employee performance reviews.
REST API serving a product catalogue, built with Node.js.
Movie discovery site in vanilla JavaScript.
Browser maze solver for an automated-guided-vehicle concept — explores 40,344 solving approaches.
A focused timer web app.
My first build: a page that speaks its content aloud, made with visually impaired visitors in mind.
04Impact
Numbers I'm proud of — earned with teams and customers, not alone.

09How I work
Clarify the problem and the people behind it.
Plan the approach before writing a line.
Create and orchestrate — reusable first.
Evaluate, test and refine.
Deploy with confidence, alongside the customer.
Share the impact — honestly.
10My work style
For 5.5+ years I've worked directly with customers — I go and talk to them, understand what they actually need, and stay with them until the product is safely in use.
I go and meet them — no long chains of hand-offs.
Capture what they ask for, and why.
Find the problem behind the request.
Plan the architecture and data flow first.
Sprint by sprint, reusable first.
Validate every path before release.
Controlled, reversible deployments.
Hand over with clear documentation.
Verified with safe limits on real data.
Close support while they settle in.
I own it, start to finish. Any issue that comes up at any stage is mine to resolve — until the customer is using their product safely and confidently.
11Let's connect
Open to new opportunities, interesting problems, or just connecting.
Pick a time that suits you — a quick intro call about a role, a project, or a problem you're solving.
Booking calendar coming soon — for now this opens an email.
