FIG. 01 — THE ENGINEER IN QUESTION

§ 01

Overview

I build backend and AI systems that remain dependable under real production constraints—from high-concurrency workflows to retrieval pipelines and recommendation services.

My work spans Java and Python services, API and database design, asynchronous processing, cloud deployment, and observability. I hold an M.S. in Computer Science from Syracuse University and bring more than three years of professional software engineering experience.

§ 02

Experience

Professional experience across backend platforms, applied machine learning, distributed workflows, and production reliability.

    Sep 2025 — Present

    Software Developer

    Honeywell

    • Migrated features from a legacy enterprise workflow platform to an ASP.NET Core, React, TypeScript, and SQL Server architecture.
    • Built approximately 15 REST endpoints covering workflow records, status transitions, assignments, search, filtering, and audit operations.
    • Enforced valid workflow state changes through explicit status-transition and validation rules, reducing invalid-state defects reaching QA.
    • Split monolithic functionality into workflow, user, notification, and reporting service modules using Entity Framework Core and LINQ over SQL Server.
    • Moved notifications, scheduled tasks, and reporting to background processing so they no longer blocked synchronous API requests.
    • Tuned a read-heavy workflow task-list and audit-search query with indexes and filters for status, assignee, and date range, cutting response time from 3.8 seconds to 1.4 seconds.
    • Raised automated coverage to approximately 60% with unit, integration, and API tests for valid flows, invalid transitions, missing fields, and error responses.

    Machine Learning Engineer

    IConsult

    • Built a personalized clothing recommendation system using collaborative filtering and behavioral signals, achieving 78% Precision@10 with cold-start strategies for new users.
    • Developed real-time recommendation APIs and persistent interaction models for a swipe-based marketplace experience, improving click-through rate by 24%.

    Software Engineer

    Mindtree

    • Built and maintained a metrics-monitoring platform that collected and visualized health data across approximately seven distributed services.
    • Developed REST APIs exposing system metrics, application health, alert configurations, and historical monitoring data.
    • Designed monitoring, alerting, configuration, and reporting service boundaries using microservice and Domain-Driven Design principles.
    • Built React and TypeScript dashboards for real-time and historical metrics including availability, response times, error rates, and resource utilization.
    • Wrote SQL Server data-access layers with Dapper and Entity Framework Core, tuning high-volume metric queries by service, environment, severity, and timestamp for aggregation and reporting.
    • Implemented configurable threshold-based alerting that notified teams when application or infrastructure health degraded.
    • Followed a Git-based SDLC with feature branches, pull requests, peer reviews, and continuous-integration checks.

Projects

Engineering records with room for decisions, evidence, verified outcomes, and source links.

P-01

PaperVeil

Native macOS utility

A local macOS 13+ menu-bar utility that places a subtle, click-through paper texture across every connected display, with presets, intensity control, application exclusions, schedules, shortcuts, and URL automation.

ENGINEERING NOTE

Built the overlay to remain non-interactive and excluded from standard macOS capture paths without requiring Screen Recording or Accessibility permissions. The release workflow covers multi-display behavior, Spaces, full-screen applications, sleep/wake, signing, and notarization readiness.

P-02

MacTouch

Apple Silicon interaction experiment

A native macOS project that turns physical taps on an Apple Silicon MacBook chassis into configurable actions by reading the machine's internal accelerometer.

ENGINEERING NOTE

Reads AppleSPUHIDDevice reports through IOKit, decodes the accelerometer stream, groups taps into single, double, and triple gestures, and exposes calibration, thresholds, cooldowns, counters, and action mapping through a menu-bar interface.

Credit Card Optimizer

Cardwise / financial decision system

A privacy-friendly application that turns a user's existing credit-card wallet and spending profile into category winners, backup cards, cap guidance, merchant recommendations, and an estimated annual value.

ENGINEERING NOTE

Built a deterministic reward engine over an issuer-sourced, schema-validated catalog. It normalizes annual spending, applies reward rates and caps, chooses fallbacks, separates raw points from estimated cash value, and keeps wallet data in the browser without bank credentials.

Geo-Climatic Prediction Pipeline

Space Applications Centre, ISRO

A machine-learning pipeline for predicting geo-climatic conditions across the Indian subcontinent from satellite, radar, LiDAR, and radiometric data.

ENGINEERING NOTE

Collected INSAT-3D satellite and DPR radar data, then normalized and flattened the heterogeneous source formats into a reusable database for model training and analysis.
